Infobesitas - 22ste jaargang nummer 2, zomer 2009
Download Deel I: Een goede behandeling begint bij de juiste diagnose- Gastrointestinal hormones and regulation of food intake
Several peptides synthesised in the gastrointestinal tract which affect food intake have been identified including ghrelin, cholecystokinin (CCK), glucagon-like peptide-1 (7-36) amide (GLP-1), oxyntomodulin, peptide YY (PYY) and pancreatic polypeptide (PP). - Leptin signaling in the hypothalamus: emphasis on energy homeostasis and leptin resistance
Leptin, the long-sought factor of adipocytes origin, has emerged as one of the major signals that relay the status of fat stores to the hypothalamus and plays a significant role in energy homeostasis. It is now established that central leptin resistance contributes to the development of diet-induced obesity and ageing associated obesity - Appetite regulation and energy balance
Thirty minutes after the start of eating, satiety signals arise from the intestinal tract and, in between meals, from the adipose tissue and liver. Satiety signals are sedative and arrest the processing of food in the intestine, hence leading to termination of eating - Elevated leptin: consequence or cause of obesity?
Once leptin resistance takes hold, each subsequent exposure to high-density food faces diminished counter-regulatory responses, leading to exacerbated weight gain - The hypothalamus, hormones, and hunger: alterations in human obesity and illness
While obese subjects have appropriate reductions in orexigenic ghrelin, other gut-hormone disturbances may contribute to obesity such as reduced anorexigenic PYY and PP - Gut hormones as peripheral anti obesity targets
Obese subjects have lower basal fasting PYY levels and have a smaller post prandial rise. - Basal and postprandial plasma levels of PYY, ghrelin, cholecystokinin, gastrin and insulin in women with moderate and morbid obesity and metabolic synd
In MOB-MS women the fasting PYY(3-36) levels were lower compared to lean controls and OB-MS, whilst postprandially in both OB-MS and MOB-MS, it was much lower than in lean women - Impaired cholecystokinin secretion and disturbed appetite regulation in women with polycystic ovary syndrome
We conclude that women with PCOS have reduced postprandial CCK secretion and deranged appetite regulation associated with increased levels of testosterone. Impaired CCK secretion may play a role in the greater frequency of binge eating and overweight in women with PCOS. - Carbohydrate cravings: a disorder of food intake and mood
Current findings on the relationship between excessive appetite for carbohydrate-rich foods and mood disorders may explain repetitive weight gain or the inability to lose weight among some obese individuals. Obese individuals who crave carbohydrates, exhibit positive changes in mood after carbohydrate intake Brain serotonin may be involved in these disorders of affect and appetite; thus therapies that mimic the effect of carbohydrate intake on the synthesis and release of this neurotransmitter may be useful in treating obesity arising from these causes - Carbohydrate craving. Relationship between carbohydrate intake and disorders of mood
The brain neurotransmitter, serotonin, seems to be involved in the abnormal regulation of mood and food intake that underlies diet failures or weight gain in individuals who suffer from carbohydrate craving obesity (CCO), premenstrual syndrome (PMS) and seasonal affective disorder (SAD). - The involvement of brain serotonin in excessive carbohydrate snacking by obese carbohydrate cravers
The subgroup of obese individuals who consume carbohydrate-rich snack foods at specific times of day or evening has been identified. Such individuals do not routinely snack on protein-rich foods, and their consumption of calories and nutrients at meals is not excessive. Evidence is presented that carbohydrate snacking seems to be related to a "need" to increase the level of brain serotonin - Brain serotonin, carbohydrate-craving, obesity and depression
Carbohydrate consumption--acting via insulin secretion and the "plasma tryptophan ratio"--increases serotonin release; protein intake lacks this effect. Hence many patients learn to overeat carbohydrates (particularly snack foods, like potato chips or pastries, which are rich in carbohydrates and fats) to make themselves feel better. This tendency to use certain foods as though they were drugs is a frequent cause of weight gain, and can also be seen in patients who become fat when exposed to stress, or in women with premenstrual syndrome, or in patients with "winter depression," or in people who are attempting to give up smoking. Nicotine, like dietary carbohydrates, increases brain serotonin secretion; nicotine withdrawal has the opposite effect - Changes in mood after carbohydrate consumption among obese individuals
Moreover, noncarbohydrate cravers experienced an increase in depression, while carbohydrate cravers reported feeling less depressed. Findings suggest that snacking habits of obese individuals may be related to subsequent mood states - Low resting metabolic rate as a risk factor for weight gain: role of the sympathetic nervous system
RMR is believed to be genetically determined. Individuals with a low RMR for a given body size are at higher risk of significant weight gain, relative to those with a high RMR - Adaptation to low energy intakes: the responses and limits to low intakes in infants, children and adults
Reduction in energy intake below the acceptable level of requirement for an individual results in a series of physiological and behavioural responses, which are considered as an adaptation to the low energy intake. This ability of the human body to adapt to a lowering of the energy intake is without doubt beneficial to the survival of the individual - Fasting--wrong in obesity?
Fasting has been advocated as an effective way to reduce body weight. However, few data support any long-term effect of this therapy. On the contrary, evidence is accumulating that the repeated weight loss and concomitant weight gain, typical of fasting in many individuals, will lead to a subsequently higher body weight. Each weight cycle seems to increase the risk of a higher waist/hip ratio, greater metabolic efficiency and a food preference towards fat. All these trends result in further problems associated with weight loss and a vicious circle is established - Effects of dieting and exercise on resting metabolic rate and implications for weight management
Resting metabolic rate accounts for 60–75% of total energy expenditure in sedentary people.2 Therefore, it is a major determinant of energy balance and changes in weight. Factors which decrease resting metabolic rate would be associated with difficulty maintaining weight or weight loss, or frank weight gain. On the contrary, anything that increases resting metabolic rate would facilitate weight loss and maintenance of weight loss. Caloric restriction is known to produce a short-term reduction in resting metabolic rate - Selection of appropriate exercise regimens for weight reduction during VLCD and maintenance
We conclude that exercise with VLCD is beneficial particularly isotonic resistance training, in improving muscular efficiency and RMR/lean - Hyperinsulinism. Causes and mechanisms
A high plasma insulin concentration in the presence of a normal or high plasma glucose level appears to be a common feature of glucose intolerance, obesity, and hypertension - Hyperinsulinism syndromes caused by insulin resistance
Resistance to insulin consists in a decrease in insulin's biologic action and is manifested mainly by hyperinsulinism - Dietary carbohydrate's effects on lipogenesis and the relationship of lipogenesis to blood insulin and glucose concentrations
The process by which dietary carbohydrate is transformed into fat in the human body is termed de novo lipogenesis - Postprandial de novo lipogenesis and metabolic changes induced by a high-carbohydrate, low-fat meal in lean and overweight men
De novo lipogenesis was significantly higher before and after meal intake in the overweight men and was positively associated with fasting serum glucose and insulin concentrations - The prevalence of the metabolic syndrome in the Netherlands: increased risk of cardiovascular diseases and diabetes mellitus type 2 in one quarter of persons under 60
Approximately 1 million Dutch adults below 60 years of age had the metabolic syndrome in the 1990's. Based on the total prevalence of the metabolic syndrome and hypercholesterolaemia, one quarter of the Dutch population younger then 60 runs an increased risk of cardiovascular disease and type 2 diabetes mellitus - The metabolic syndrome in women
The metabolic syndrome is estimated to be present in 47 million US residents with a similar age-adjusted prevalence in men (24%) and women (23%). - Obesity and the metabolic syndrome
The metabolic syndrome associated with abdominal obesity, which includes insulin resistance, dyslipidemia, and elevated CRP levels, identifies subjects who have an increase in cardiovascular morbidity and mortality. Twenty to 25% of the adult population in the United States have the metabolic syndrome, and in some older groups this prevalence approaches 50%. - Visceral and subcutaneous adiposity: are both potential therapeutic targets for tackling the metabolic syndrome?
The metabolic syndrome represents a constellation of co-morbidities that include central adiposity, insulin resistance, dyslipidemia and hypertension, which results from an elevated prevalence of obesity. - Hypothyroidism: common complaints, perplexing diagnosis
The disease affects every major organ system and metabolic process. The diagnosis of primary hypothyroidism can be perplexing to the clinician because of its insidious onset and wide array of nonspecific manifestations. Complaints of fatigue, muscle weakness, lethargy, and weight gain are often at first attributed to emotional or other health problems. Additionally, patients may not seek medical care because they are unaware that they are ill - Hypothyroidism and women's health
Hypothyroidism affects 4% to 10% of women, increasing with age. Symptoms, which are often nonspecific and subtle, can include: lethargy, mild weight gain, edema, cold intolerance, constipation, mental impairment, dry skin, depression, irregular menses, hoarseness, myalgias, hyperlipidemia, and bradycardia. - Hypothyroidism in the elderly: pathophysiology, diagnosis and treatment
Some degree of hypothyroidism is common in the elderly. It affects 5-20% of women and 3-8% of men. - Clinical aspects of recurrent postpartum thyroiditis
Postpartum thyroiditis (PPT), characterized by transient hyperthyroidism and transient hypothyroidism, occurs in 5-9% of women. There was a 70% chance of developing recurrent PPT after a first attack, and a 25% risk even in women who were only anti-TPO positive without thyroid dysfunction during the first postpartum period. The recurrence of postpartum depression was not related to thyroid function. Patients noted to have thyroid dysfunction or just to be euthyroid but anti-TPO positive after pregnancy should be assessed carefully after a subsequent pregnancy

Download Deel II: Niet ieder pondje komt door het mondje - van juiste diagnose naar passende behandeling- Alemany M. Prog Food Nutr Sci. 1989;13(1):45-66. The etiologic basis for the classification of obesity
The physiologic and metabolic pathways responsible of the appearance of obesity are revisited, as well as the current theories on body weight regulatory mechanisms. From this information, a classification of obesities is proposed: 1) Hypothalamic, 2) Bulimic, 3) Digestive, 4) Hyperinsulinemic, 5) Hypothermogenic, 6) Hypothyroid, and 7) Set point. - Alemany M. Prog Food Nutr Sci. 1989;13(1):45-66. The etiologic basis for the classification of obesity
These conditions should not be treated therapeutically in the same way, as the causes of development of the illness are not equal. The need to determine the individualized causes of obesity prior to any treatment is stressed - Erlanson-Albertsson C. Acta Paediatr Suppl. 2005 Jun;94(448):40-1. Appetite regulation and energy balance
Thirty minutes after the start of eating, satiety signals arise from the intestinal tract and, in between meals, from the adipose tissue and liver. Satiety signals are sedative and arrest the processing of food in the intestine, hence leading to termination of eating. - Andrade AM, Greene GW, Melanson KJ. J Am Diet Assoc. 2008 Jul;108(7):1186-91 Eating slowly led to decreases in energy intake within meals in healthy women
Ad libitum energy intake was lower when the meal was eaten slowly, and satiety was higher at meal completion. Although more study is needed, these data suggest that eating slowly may help to maximize satiation and reduce energy intake within meals - Speechly DP, Rogers GG, Buffenstein R. Int J Obes Relat Metab Disord. 1999 Nov;23(11):1151-9. Acute appetite reduction associated with an increased frequency of eating in obese males
Obese males fed an isoenergetic pre-load sub-divided into a multi-meal plan consumed 27% less at a subsequent ad libitum test meal than did the same men when given the pre-load as a single meal. Prolonged but attenuated increases in serum insulin concentration on the multi-meal programme may facilitate this acute reduction in appetite - Speechly DP, Buffenstein R. Appetite. 1999 Dec;33(3):285-97. Greater appetite control associated with an increased frequency of eating in lean males
These data suggest that when the nutrient load was spread into equal amounts and consumed evenly through the day in lean healthy males, there was an enhanced control of appetite. This greater control of satiety when consuming smaller multiple meals may possibly be linked to an attenuation in insulin response although clearly both other physical (gastric stretch) and physiological (release of gastric hormones) factors may also be affected by the periodicity of eating - Mota J, Fidalgo F, Silva R, Ribeiro JC, Santos R, Carvalho J, Santos MP. Ann Hum Biol. 2008 Jan-Feb;35(1):1-10 Relationships between physical activity, obesity and meal frequency in adolescents
The data indicate that increased meal frequency may have a beneficial effect on a reduced BMI. Physical activity and breakfast skipping may be candidate targets for prevention programmes aimed at reducing overweight/obesity among adolescents - Louis-Sylvestre J, Lluch A, Neant F, Blundell JE. Forum Nutr. 2003;56:126-8 Highlighting the positive impact of increasing feeding frequency on metabolism and weight management
Research on feeding frequency started more than 20 years ago and some studies have shown evidence of nutritional benefits, especially on metabolism and body weight management. The experts agreed that, as long as we do not consume more energy than we use up and we only eat when we are hungry, it may be useful to split our total energy intake into as many meals as our social pattern allows - Toschke AM, Küchenhoff H, Koletzko B, von Kries R. Obes Res. 2005 Nov;13(11):1932-8 Meal frequency and childhood obesity
The prevalence of obesity decreased by number of daily meals: three or fewer meals, 4.2% [95% confidence interval (CI), 2.8 to 6.1]; four meals, 2.8% (95% CI, 2.1 to 3.7); and 5 or more meals, 1.7% (95% CI, 1.2 to 2.4). These effects could not be explained by confounding due to a wide range of constitutional, sociodemographic, and lifestyle factors. - Toschke AM, Küchenhoff H, Koletzko B, von Kries R. Obes Res. 2005 Nov;13(11):1932-8 Meal frequency and childhood obesity
A protective effect of an increased daily meal frequency on obesity in children was observed and appeared to be independent of other risk factors for childhood obesity. A modulation of the response of hormones such as insulin might be instrumental - Westerterp-Plantenga MS, Lejeune MP, Nijs I, van Ooijen M, Kovacs EM. Int J Obes Relat Metab Disord. 2004 Jan;28(1):57-64. High protein intake sustains weight maintenance after body weight loss in humans
A 20% higher protein intake, that is, 18% of energy vs 15% of energy during weight maintenance after weight loss, resulted in a 50% lower body weight regain, only consisting of fat-free mass, and related to increased satiety and decreased energy efficiency - Halton TL, Hu FB. J Am Coll Nutr. 2004 Oct;23(5):373-85 The effects of high protein diets on thermogenesis, satiety and weight loss: a critical review
There is convincing evidence that a higher protein intake increases thermogenesis and satiety compared to diets of lower protein content. The weight of evidence also suggests that high protein meals lead to a reduced subsequent energy intake. - Westerterp-Plantenga MS. Curr Opin Clin Nutr Metab Care. 2003 Nov;6(6):635-8 The significance of protein in food intake and body weight regulation
Protein is more satiating than carbohydrate and fat in the short term, over 24 h and in the long term. Thermogenesis plays a role in this satiety effect, but the role of satiety hormones still needs to be elucidated. On the short-term 'fast' proteins are more satiating than 'slow' proteins, and animal protein induces a higher thermogenesis than vegetable protein - Rigaud D, Ryttig KR, Leeds AR, Bard D, Apfelbaum M. Int J Obes. 1987;11 Suppl 1:73-8 Effects of a moderate dietary fibre supplement on hunger rating, energy input and faecal energy output in young, healthy volunteers. A randomized, double-blind, cross-over trial
This study demonstrated that moderate dietary fibre supplementation in normal man increases faecal energy excretion with simultaneously decreased hunger feeling. These beneficial effects may have therapeutic value in the management of obesity - Rigaud D, Ryttig KR, Angel LA, Apfelbaum M. Int J Obes. 1990 Sep;14(9):763-9. Overweight treated with energy restriction and a dietary fibre supplement: a 6-month randomized, double-blind, placebo-controlled trial
After treatment the weight reduction in the fibre-treated group, 5.5 +/- 0.7 kg, was significantly higher than that of the placebo group, 3.0 +/- 0.5 kg (P = 0.005). Hunger feelings using visual analogue scales (VAS) were significantly reduced from 139.8 +/- 8.2 cm to 118.3 +/- 7.0 cm in the fibre-treated group, whereas a significant increase from 129.5 +/- 6.9 cm to 146.9 +/- 8.8 cm (P less than 0.02) was seen in the placebo group - Rigaud D, Paycha F, Meulemans A, Merrouche M, Mignon M. Eur J Clin Nutr. 1998 Apr;52(4):239-45 Effect of psyllium on gastric emptying, hunger feeling and food intake in normal volunteers: a double blind study
Psyllium reduces hunger feelings and energy intake in normal volunteers at reasonable dose and without requiring mixing with the meal. It does not act by slowing down the gastric emptying of hydrosoluble nutrients, but by increase in the time allowed for intestinal absorption, as suggested by the flattening of the postprandial serum glucose, insulin and triglycerides curves - Bergmann JF, Chassany O, Petit A, Triki R, Caulin C, Segrestaa JM. Gut. 1992 Aug;33(8):1042-3 Correlation between echographic gastric emptying and appetite: influence of psyllium
The correlation between echographic gastric emptying and sensations of hunger and satiety was excellent (p < 0.001) after the intake of either psyllium or placebo. Psyllium significantly delayed gastric emptying from the third hour after a meal. It increased the sensation of satiety and decreased hunger at the sixth hour after the meal - Keithley J, Swanson B. Altern Ther Health Med. 2005 Nov-Dec;11(6):30-4 Glucomannan and obesity: a critical review
At doses of 2-4 g per day, GM was well-tolerated and resulted in significant weight loss in overweight and obese individuals. There is some evidence that GM exerts its beneficial effects by promoting satiety and fecal energy loss. Additionally, GM has been shown to improve lipid and lipoprotein parameters and glycemic status - Walsh DE, Yaghoubian V, Behforooz A Int J Obes. 1984;8(4):289-93 Effect of glucomannan on obese patients: a clinical study
Results showed a significant mean weight loss (5.5 lbs) using glucomannan over an eight-week period. Serum cholesterol and low-density lipoprotein cholesterol were significantly reduced (21.7 and 15.0 mg/dl respectively) in the glucomannan treated group. No adverse reactions to glucomannan were reported - Vita PM, Restelli A, Caspani P, Klinger R. Minerva Med. 1992 Mar;83(3):135-9. Chronic use of glucomannan in the dietary treatment of severe obesity
The comparative analysis of the results obtained in both groups showed that the diet + glucomannan group had a more significant weight loss in relation to the fatty mass alone, an overall improvement in lipid status and carbohydrate tolerance, and a greater adherence to the diet in the absence of any relevant side effects. Due to the marked ability to satiate patients and the positive metabolic effects, glucomannan diet supplements have been found to be particularly efficacious and well tolerated even in the long-term treatment of severe obesity - Wurtman JJ. Clin Neuropharmacol. 1988;11 Suppl 1:S139-45 Carbohydrate cravings: a disorder of food intake and mood
Current findings on the relationship between excessive appetite for carbohydrate-rich foods and mood disorders may explain repetitive weight gain or the inability to lose weight among some obese individuals. Obese individuals who crave carbohydrates, exhibit positive changes in mood after carbohydrate intake; Brain serotonin may be involved in these disorders of affect and appetite; thus therapies that mimic the effect of carbohydrate intake on the synthesis and release of this neurotransmitter may be useful in treating obesity arising from these causes - Wurtman JJ.J Am Diet Assoc. 1984 Sep;84(9):1004-7. The involvement of brain serotonin in excessive carbohydrate snacking by obese carbohydrate cravers
A specific hunger for carbohydrate-rich foods has been observed in animals and human beings and appears to be regulated by the brain neurotransmitter serotonin. Consumption of a carbohydrate-rich meal increases the synthesis and release of brain serotonin. Evidence is presented that carbohydrate snacking seems to be related to a "need" to increase the level of brain serotonin - Josephine Connolly, Theresa Romano and Marisa Patruno Family Practice Vol. 16, No. 2, 196-201 Effects of dieting and exercise on resting metabolic rate and implications for weight management
Resting metabolic rate accounts for 60–75% of total energy expenditure in sedentary people. Therefore, it is a major determinant of energy balance and changes in weight. Factors which decrease resting metabolic rate would be associated with difficulty maintaining weight or weight loss, or frank weight gain. On the contrary, anything that increases resting metabolic rate would facilitate weight loss and maintenance of weight loss. Caloric restriction is known to produce a short-term reduction in resting metabolic rate - Byrne HK, Wilmore JH. Int J Sport Nutr Exerc Metab. 2001 Mar;11(1):15-31. The effects of a 20-week exercise training program on resting metabolic rate in previously sedentary, moderately obese women
Resistance training (RT) can potentiate an increase in RMR through an increase in fat-free mass. - Lemons AD, Kreitzman SN, Coxon A, Howard A. Int J Obes. 1989;13 Suppl 2:119-23 Selection of appropriate exercise regimens for weight reduction during VLCD and maintenance
We conclude that exercise with VLCD is beneficial particularly isotonic resistance training, in improving muscular efficiency and RMR/lean. - Del Prato S. Presse Med. 1992 Sep 9;21(28):1312-7. Hyperinsulinism. Causes and mechanisms
A high plasma insulin concentration in the presence of a normal or high plasma glucose level appears to be a common feature of glucose intolerance, obesity, and hypertension - Achten J, Jeukendrup AE. Nutrition. 2004 Jul-Aug;20(7-8):716-27 Optimizing fat oxidation through exercise and diet
Ingestion of carbohydrate in the hours before or on commencement of exercise reduces the rate of fat oxidation significantly compared with fasted conditions, whereas fasting longer than 6 h optimizes fat oxidation. Fat oxidation rates have been shown to decrease after ingestion of high-fat diets, partly as a result of decreased glycogen stores and partly because of adaptations at the muscle level - Martin WH 3rd. Exerc Sport Sci Rev. 1996;24:203-31 Effects of acute and chronic exercise on fat metabolism.
Fatty acids are an important source of energy for skeletal muscle contraction, particularly during exercise of mild-moderate intensity, prolonged duration, and in the fasting state - Lejeune MP, Westerterp KR, Adam TC, Luscombe-Marsh ND, Westerterp-Plantenga MS. Am J Clin Nutr. 2006 Jan;83(1):89-94 Am J Clin Nutr. 2006 Jan;83(1):89-94 Ghrelin and glucagon-like peptide 1 concentrations, 24-h satiety, and energy and substrate metabolism during a high-protein diet and measured in a respiration chamber
An HP diet, compared with an AP diet, fed at energy balance for 4 d increased 24-h satiety, thermogenesis, sleeping metabolic rate, protein balance, and fat oxidation. Satiety was related to protein intake, and incidentally to ghrelin and GLP-1 concentrations, only during the HP diet - No authors listed Diabetes Educ. 2004;Suppl:2-14. A scientific review: the role of chromium in insulin resistance
Chromium is an essential mineral that appears to have a beneficial role in the regulation of insulin action and its effects on carbohydrate, protein and lipid metabolism. Chromium is an important factor for enhancing insulin activity. Chromium picolinate, specifically, has been shown to reduce insulin resistance. Supplements containing 200-1,000 mcg chromium as chromium picolinate a day have been found to improve blood glucose control. Chromium picolinate is the most efficacious form of chromium supplementation. Numerous animal studies and human clinical trials have demonstrated that chromium picolinate supplements are safe - Hummel M, Standl E, Schnell O. Horm Metab Res. 2007 Oct;39(10):743-51 Chromium in metabolic and cardiovascular disease
Chromium is an essential mineral that appears to have a beneficial role in the regulation of insulin action, metabolic syndrome, and cardiovascular disease. There is growing evidence that chromium may facilitate insulin signaling and chromium supplementation therefore may improve systemic insulin sensitivity. Since chromium supplementation is a safe treatment, further research is necessary to resolve the confounding data. The existing data suggest to concentrate future studies on certain forms as chromium picolinate and doses as at least 200 mcg per day - Takaya J, Magnes Res. 2004 Jun;17(2):126-36 Intracellular magnesium and insulin resistance
Magnesium is required for both proper glucose utilization and insulin signaling. Metabolic alterations in cellular magnesium, which may play the role of a second messenger for insulin action, contribute to insulin resistance. - Belin RJ, He K. Magnes Res. 2007 Jun;20(2):107-29 Magnesium physiology and pathogenic mechanisms that contribute to the development of the metabolic syndrome
Recently, there has been burgeoning experimental, clinical, and epidemiological data that provides strong evidence that dietary magnesium intake and supplementation are inversely associated with the risk for MetS and its components. - Fox CS, Pencina MJ, D'Agostino RB, Murabito JM, Seely EW, Pearce EN, Vasan RS. Arch Intern Med. 2008 Mar 24;168(6):587-92 Relations of thyroid function to body weight: cross-sectional and longitudinal observations in a community-based sample
Thyroid function (as assessed by serum TSH concentration) within the reference range is associated with body weight in both sexes. Our findings raise the possibility that modest increases in serum TSH concentrations within the reference range may be associated with weight gain - CBG-Med, 13 december 2007 - Hyperiplant als eerste geneesmiddel op basis van St.Janskruid geregistreerd

Overweight and obese adults had higher odds of low levels for a number of nutrients compared with normal-weight adults. Odds of being low in multiple micronutrients was most common among overweight and obese premenopausal women - Docherty JP, Sack DA, Roffman M, Finch M, Komorowski JR. J Psychiatr Pract. 2005 Sep;11(5):302-14 double-blind, placebo-controlled, exploratory trial of chromium picolinate in atypical depression: effect on carbohydrate craving
The results of this study suggest that the main effect of chromium was on carbohydrate craving and appetite regulation in depressed patients and that 600 mug of elemental chromium may be beneficial for patients with atypical depression who also have severe carbohydrate craving - Diabetes Educ. 2004;Suppl:2-14 A scientific review: the role of chromium in insulin resistance
Chromium is an essential mineral that appears to have a beneficial role in the regulation of insulin action and its effects on carbohydrate, protein and lipid metabolism. Chromium picolinate, specifically, has been shown to reduce insulin resistance and to help reduce the risk of cardiovascular disease and type 2 diabetes - Kleefstra N, Bilo HJ, Bakker SJ, Houweling ST. Ned Tijdschr Geneeskd. 2004 Jan 31;148(5):217-20. Chromium and insulin resistance
Since as early as the 50s of the last century, it has been known that chromium is essential for normal glucose metabolism. Too little chromium in the diet may lead to insulin resistance. In a double-blind randomised placebo-controlled trial in a Chinese population with type-2 diabetes mellitus, supplementation with 1000 micrograms of chromium led to a fall in the glycosylated haemoglobin level (HbA1c) by 2%. Toxic effects of chromium are seldom seen - Marlett JA, McBurney MI, Slavin JL; American Dietetic Association. J Am Diet Assoc. 2002 Jul;102(7):993-1000 Position of the American Dietetic Association: health implications of dietary fiber
Dietary fiber consists of the structural and storage polysaccharides and lignin in plants that are not digested in the human stomach and small intestine. A wealth of information supports the American Dietetic Association position that the public should consume adequate amounts of dietary fiber from a variety of plant foods. Recommended intakes, 20-35 g/day for healthy adults and age plus 5 g/day for children, are not being met, because intakes of good sources of dietary fiber, fruits, vegetables, whole and high-fiber grain products, and legumes are low - Bartalena L, Bogazzi F, Brogioni S, Burelli A, Scarcello G, Martino E. Horm Res. 1996;45(3-5):142-7 Measurement of serum free thyroid hormone concentrations: an essential tool for the diagnosis of thyroid dysfunction
When hypothyroidism is suspected, the most reliable test appears to be FT4 (together with TSH), because FT3 may still be normal in patients with subclinical or mild thyroid failure - Wémeau JL, Lefebvre J, Linquette M. Nouv Presse Med. 1979 Feb 3;8(6):415-9. ["Low triiodothyronine (T3) syndrome": "thyroxine (T4) euthyroidism" evidence
As first described in serious systemic illnesses isolated decreased T3 plasma concentration was related to impaired peripheral conversion of T4, to T3 with preferential production of reverse T3 (rT3). A "low T3 syndrome" was seen in 47 out of 109 patients with extra-thyroidal diseases. Metabolic state, TSH and TSH responses to TRH were normal despite of low T3 concentration. Euthyroidism seems mainly due to T4 itself in these patients - Roti E, Minelli R, Salvi M. Int J Obes Relat Metab Disord. 2000 Jun;24 Suppl 2:S113-5. Thyroid hormone metabolism in obesity
Serum thyroid hormone concentrations and their metabolic fate are within the normal range limits in obese subjects. Also serum TSH concentrations and its response to TRH are normal, suggesting that tissue availability of thyroid hormones is normally preserved in these subjects. In contrast, during caloric restriction serum T3 concentrations decrease as a consequence of its reduced production rate from peripheral deiodination of T4. - Rössner S. Nord Med. 1990;105(6-7):190-1. Fasting--wrong in obesity?
Fasting has been advocated as an effective way to reduce body weight. However, few data support any long-term effect of this therapy. On the contrary, evidence is accumulating that the repeated weight loss and concomitant weight gain, typical of fasting in many individuals, will lead to a subsequently higher body weight. Each weight cycle seems to increase the risk of a higher waist/hip ratio, greater metabolic efficiency and a food preference towards fat. All these trends result in further problems associated with weight loss and a vicious circle is established

Potential beneficial outcomes associated with protein ingestion include the following: 1) increased satiety--protein generally increases satiety to a greater extent than carbohydrate or fat and may facilitate a reduction in energy consumption under ad libitum dietary conditions; 2) increased thermogenesis--higher-protein diets are associated with increased thermogenesis, which also influences satiety and augments energy expenditure (in the longer term, increased thermogenesis contributes to the relatively low-energy efficiency of protein); and 3) maintenance or accretion of fat-free mass--in some individuals, a moderately higher protein diet may provide a stimulatory effect on muscle protein anabolism, favoring the retention of lean muscle mass while improving metabolic profile. - Halton TL, Hu FB. J Am Coll Nutr. 2004 Oct;23(5):373-85 The effects of high protein diets on thermogenesis, satiety and weight loss: a critical review

In humans, insulin sensitivity is relatively impaired by diets that are low in oleic acid (OA), a cis monounsaturated fatty acid (MUFA), or rich in trans MUFA or palmitic acid (PA), a saturated fatty acid (FA). - Fedor D, Kelley DS. Curr Opin Clin Nutr Metab Care. 2009 Mar;12(2):138-46 Prevention of insulin resistance by n-3 polyunsaturated fatty acids
n-3 PUFA supplementation has clinical significance in the prevention and reversal of insulin resistance. However, increased intake of n-3 PUFA should be part of an overall healthy lifestyle that includes weight control, exercise, and reduction in the intake of refined sugars, n-6, saturated, and trans fatty acids. - Delarue J, LeFoll C, Corporeau C, Lucas D. Reprod Nutr Dev. 2004 May-Jun;44(3):289-99 N-3 long chain polyunsaturated fatty acids: a nutritional tool to prevent insulin resistance associated to type 2 diabetes and obesity?
In rodents in vivo, n-3 LC-PUFA have a protective effect against high fat diet induced insulin resistance. These effects are encouraging in the perspective of prevention of insulin resistance but further clinical and basic studies must be designed to confirm and complete our knowledge in this field. - Ramel A, Martinéz A, Kiely M, Morais G, Bandarra NM, Thorsdottir I.

After consumption of nine macronutrient-matched portions of fiber-enriched bread (white bread enriched with 31.2 g insoluble fiber/day) or control (white bread) over a time period of 72 h, whole-body insulin sensitivity was assessed by euglycemic-hyperinsulinemic clamp. Increased insoluble dietary fiber intake for 3 days significantly improved whole-body insulin sensitivity. These data suggest a potential mechanism linking cereal fiber intake and reduced risk of type 2 diabetes. - Aleixandre A, Miguel M. Crit Rev Food Sci Nutr. 2008 Nov;48(10):905-12 Dietary fiber in the prevention and treatment of metabolic syndrome: a review
Inclusion of fiber in the diet has been linked to the prevention of a range of illnesses and conditions. This review contains several ideas about the possible benefits of dietary fiber intake in patients with metabolic syndrome. The principal beneficial effects of a fiber-rich diet in these patients are: prevention of obesity, improved glucose levels, and control of the profile of blood lipids. - Davy BM, Melby CL. J Am Diet Assoc. 2003 Jan;103(1):86-96 The effect of fiber-rich carbohydrates on features of Syndrome X
There has been much debate among nutritionists and scientists regarding the optimal dietary approach for the treatment of the Insulin Resistance Syndrome, also called Syndrome X. This review indicates that an HCLF dietary pattern such as that used in the DASH trial, with a level of dietary fiber consistent with the recommendations of the American Dietetic Association (eg, 20-35g/day), containing from 3 to 10 g soluble fiber/day, may be beneficial for treating those with Syndrome X. - Galisteo M, Duarte J, Zarzuelo A. J Nutr Biochem. 2008 Feb;19(2):71-84. Epub 2007 Jul 6 Effects of dietary fibers on disturbances clustered in the metabolic syndrome
Because of its growing prevalence in Western countries, the metabolic syndrome, a common metabolic disorder that clusters a constellation of abnormalities, including central obesity, hypertension, dyslipidemia and insulin resistance. Among dietary modifications, dietary fiber intake could play an interesting role in the management of metabolic syndrome through different mechanisms related to its dietary sources, specific chemical structure and physical properties, or fermentability in the gut. - Giugliano D, Esposito K. Curr Opin Lipidol. 2008 Feb;19(1):63-8 Mediterranean diet and metabolic diseases
Mounting evidence suggests that Mediterranean diets could serve as an anti-inflammatory dietary pattern, which could help fighting diseases that are related to chronic inflammation, including visceral obesity, type 2 diabetes and the metabolic syndrome. - Giugliano D, Ceriello A, Esposito K.

J Am Coll Nutr. 2001 Apr;20(2 Suppl):97-105 High-energy diets, fatty acids and endothelial cell function: implications for atherosclerosis
Our studies suggest that omega-6 fatty acids, and especially linoleic acid, cause endothelial cell dysfunction most markedly as well as can potentiate TNF-mediated endothelial cell injury. We propose that high-energy diets, and especially diets rich in linoleic acid, are atherogenic by contributing to an imbalance in cellular oxidative stress/antioxidant status of the endothelium, which can lead to activation of oxidative stress-responsive transcription factors, inflammatory cytokine production and the expression of adhesion molecules. - Voedingscentrum Vetwijzer

Anthropological and epidemiological studies and studies at the molecular level indicate that human beings evolved on a diet with a ratio of omega-6 to omega-3 essential fatty acids (EFA) of approximately 1 whereas in Western diets the ratio is 15/1 to 16.7/1. A high omega-6/omega-3 ratio, as is found in today's Western diets, promotes the pathogenesis of many diseases, including cardiovascular disease, cancer, osteoporosis, and inflammatory and autoimmune diseases, whereas increased levels of omega-3 polyunsaturated fatty acids (PUFA) (a lower omega-6/omega-3 ratio), exert suppressive effects. - Simopoulos AP. Exp Biol Med (Maywood). 2008 Jun;233(6):674-88 The importance of the omega-6/omega-3 fatty acid ratio in cardiovascular disease and other chronic diseases
Several sources of information suggest that human beings evolved on a diet with a ratio of omega-6 to omega-3 essential fatty acids (EFA) of approximately 1 whereas in Western diets the ratio is 15/1-16.7/1. A lower ratio of omega-6/omega-3 fatty acids is more desirable in reducing the risk of many of the chronic diseases of high prevalence in Western societies, as well as in the developing countries. - Weiss LA, Barrett-Connor E, von Mühlen D. Am J Clin Nutr. 2005 Apr;81(4):934-8 Ratio of n-6 to n-3 fatty acids and bone mineral density in older adults: the Rancho Bernardo Study
A higher ratio of n-6 to n-3 fatty acids is associated with lower BMD at the hip in both sexes. These findings suggest that the relative amounts of dietary polyunsaturated fatty acids may play a vital role in preserving skeletal integrity in older age. - Calder PC. Mol Nutr Food Res. 2008 Aug;52(8):885-97 Polyunsaturated fatty acids, inflammatory processes and inflammatory bowel diseases
With regard to inflammatory processes, the main fatty acids of interest are the n-6 PUFA arachidonic acid (AA), which is the precursor of inflammatory eicosanoids like prostaglandin E(2) and leukotriene B(4), and the n-3 PUFAs eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA and DHA are found in oily fish and fish oils. EPA and DHA inhibit AA metabolism to inflammatory eicosanoids. - Simopoulos AP. J Am Coll Nutr. 2002 Dec;21(6):495-505 Omega-3 fatty acids in inflammation and autoimmune diseases
Animal experiments and clinical intervention studies indicate that omega-3 fatty acids have anti-inflammatory properties and, therefore, might be useful in the management of inflammatory and autoimmune diseases. Coronary heart disease, major depression, aging and cancer are characterized by an increased level of interleukin 1 (IL-1), a proinflammatory cytokine. Similarly, arthritis, Crohn's disease, ulcerative colitis and lupus erythematosis are autoimmune diseases characterized by a high level of IL-1 and the proinflammatory leukotriene LTB(4) produced by omega-6 fatty acids. - Margioris AN. Curr Opin Clin Nutr Metab Care. 2009 Mar;12(2):129-37 Fatty acids and postprandial inflammation

Proc Nutr Soc. 2003 Feb;62(1):143-9 Epidemiological support for the protection of whole grains against diabetes
Intake of wholegrain foods may reduce diabetes risk. Three prospective studies in 160000 men and women examined the relationship of whole-grain or cereal-fibre intake with the risk of type 2 diabetes. Risk for incident type 2 diabetes was 21-27% lower for those in the highest quintile of whole-grain intake, and 30-36% lower in the highest quintile of cereal-fibre intake, each compared with the lowest quintile - McKeown NM. Nutr Rev. 2004 Jul;62(7 Pt 1):286-91 Whole grain intake and insulin sensitivity: evidence from observational studies
Observational studies have found that diets rich in whole-grain foods are associated with improved insulin sensitivity. The improved insulin sensitivity may be mediated in part by magnesium and dietary fiber, two nutrients found in whole-grain foods. By incorporating whole-grain foods into the diet, therefore, insulin sensitivity might be improved - Liese AD, Roach AK, Sparks KC, Marquart L, D'Agostino RB Jr, Mayer-Davis EJ.

The consumption of HFCS increased > 1000% between 1970 and 1990, far exceeding the changes in intake of any other food or food group. Thus, the increase in consumption of HFCS has a temporal relation to the epidemic of obesity, and the overconsumption of HFCS in calorically sweetened beverages may play a role in the epidemic of obesity. - Stanhope KL, Havel PJ.

J Clin Endocrinol Metab. 2004 Jun;89(6):2963-72 Dietary fructose reduces circulating insulin and leptin, attenuates postprandial suppression of ghrelin, and increases triglycerides in women
Consumption of HFr meals produced a rapid and prolonged elevation of plasma triglycerides compared with the HGl day (P < 0.005). Because insulin and leptin, and possibly ghrelin, function as key signals to the central nervous system in the long-term regulation of energy balance, decreases of circulating insulin and leptin and increased ghrelin concentrations, as demonstrated in this study, could lead to increased caloric intake and ultimately contribute to weight gain and obesity during chronic consumption of diets high in fructose. - Ouyang X, Cirillo P, Sautin Y, McCall S, Bruchette JL, Diehl AM, Johnson RJ, Abdelmalek MF.

In the last decades there has been a great controversy about the consumption of margarine due to the levels of trans fatty acids they contain. - Salmerón J, Hu FB, Manson JE, Stampfer MJ, Colditz GA, Rimm EB, Willett WC. Am J Clin Nutr. 2001 Jun;73(6):1019-26 Dietary fat intake and risk of type 2 diabetes in women
These data suggest that total fat and saturated and monounsaturated fatty acid intakes are not associated with risk of type 2 diabetes in women, but that trans fatty acids increase and polyunsaturated fatty acids reduce risk. - Mozaffarian D. Atheroscler Suppl. 2006 May;7(2):29-32. Trans fatty acids - effects on systemic inflammation and endothelial function
Consumption of trans fatty acids (TFA) predicts higher risk of coronary heart disease, sudden death, and possibly diabetes mellitus. These associations are greater than would be predicted by effects of TFA on serum lipoproteins alone. - Mozaffarian D, Willett WC.

A high serum level of trans-monounsaturated fatty acids, presumably reflecting a high intake of industrially processed foods, is probably one factor contributing to increased risk of invasive breast cancer in women. - Micha R, Mozaffarian D. Nat Rev Endocrinol. 2009 Jun;5(6):335-44. Trans fatty acids: effects on metabolic syndrome, heart disease and diabetes
The major dietary sources of trans fatty acids (TFAs) in most countries are partially hydrogenated vegetable oils. TFA consumption is a modifiable dietary risk factor for metabolic syndrome, diabetes mellitus, and coronary heart disease. TFA consumption causes metabolic dysfunction: it adversely affects circulating lipid levels, triggers systemic inflammation, induces endothelial dysfunction, and, according to some studies, increases visceral adiposity, body weight, and insulin resistance. - Dorfman SE, Laurent D, Gounarides JS, Li X, Mullarkey TL, Rocheford EC, Sari-Sarraf F, Hirsch EA, Hughes TE, Commerford SR. Obesity (Silver Spring). 2009 Jun;17(6):1200-7. Metabolic implications of dietary trans-fatty acids
These findings imply that trans-fatty acids may alter nutrient handling in liver, adipose tissue, and skeletal muscle and that the mechanism by which trans-fatty acids induce insulin resistance differs from diets enriched with saturated fats. - Osso FS, Moreira AS, Teixeira MT, Pereira RO, Tavares do Carmo MG, Moura AS. Nutrition. 2008 Jul-Aug;24(7-8):727-32. Trans fatty acids in maternal milk lead to cardiac insulin resistance in adult offspring
Our data suggest that the consumption of hydrogenated fat, rich in TFAs, by the mothers during the lactation period caused cardiac insulin resistance in the adult progeny, thus reinforcing the hypothesis that early adaptations may cause deleterious consequences later in life. - Albuquerque KT, Sardinha FL, Telles MM, Watanabe RL, Nascimento CM, Tavares do Carmo MG, Ribeiro EB. Nutrition. 2006 Jul-Aug;22(7-8):820-9 Intake of trans fatty acid-rich hydrogenated fat during
pregnancy and lactation inhibits the hypophagic effect of central insulin in the adult offspring The data suggest that the early (intrauterine/perinatal) exposure to hydrogenated fat rich in trans fatty acids programmed the hypothalamic feeding control mechanisms. As young adults, only trans-control animals showed loss of insulin-induced hypophagia, indicating that the mismatch between early and later nutritional environments was relevant. However, the trans group also showed signs of altered appetite signaling mechanisms, suggesting that the early adaptations may have deleterious consequences later in life. - Gezondheid Raad Enkele belangrijke ontwikkelingen in de voedselconsumptie

J Am Diet Assoc. 2002 Jul;102(7):993-1000 Position of the American Dietetic Association: health implications of dietary fiber
Dietary fiber consists of the structural and storage polysaccharides and lignin in plants that are not digested in the human stomach and small intestine. A wealth of information supports the American Dietetic Association position that the public should consume adequate amounts of dietary fiber from a variety of plant foods. Recommended intakes, 20-35 g/day for healthy adults and age plus 5 g/day for children, are not being met, because intakes of good sources of dietary fiber, fruits, vegetables, whole and high-fiber grain products, and legumes are low. - Gezondheidsraad, 2006; publicatie nr 2006/03. ISBN 90-5549-589-1 Richtlijn voor de vezelconsumptie
Voedingsvezels zijn delen van planten die door de mens niet worden verteerd. Ze hebben een gunstige invloed op de gezondheid. Voor twee effecten bestaat overtuigend wetenschappelijk bewijs: voldoende inname leidt tot een betere darmwerking en beschermt tegen hartziekten. Op basis van deze kennis formuleert de Gezondheidsraad nu een nieuwe richtlijn voor de vezelconsumptie. Voor volwassenen luidt die: 3,4 gram voedingsvezel per megajoule (14 gram per 1000 kilocalorieën), wat neerkomt op 30 tot 40 gram per dag. Deze richtlijn betreft vezels die van nature voorkomen in voedingsmiddelen. Op dit moment komt negentig procent van de Nederlandse bevolking niet aan de hoeveelheid voedingsvezel die in de richtlijn is verwoord. - Voedingscentrum Smeersel met weinig vet zijn de beste keuze
Het Voorlichtingsbureau Margarine, Vetten en Oliën (MVO) is een campagne gestart om het besmeren van brood te promoten. Onder het motto ‘Een boterham is gezond, maar een boterham met margarine is gezonder’ wordt aangegeven dat het besmeren van brood een belangrijke bijdrage levert aan een gezond eetpatroon. Het Voedingscentrum is het daarmee eens, maar geeft daarbij de voorkeur aan smeersels met zo min mogelijk vet.

Gut. 1992 Aug;33(8):1042-3 Correlation between echographic gastric emptying and appetite: influence of psyllium
The correlation between echographic gastric emptying and sensations of hunger and satiety was excellent (p < 0.001) after the intake of either psyllium or placebo. Psyllium significantly delayed gastric emptying from the third hour after a meal. It increased the sensation of satiety and decreased hunger at the sixth hour after the meal. - Voedingscentrum 16 februari 2009 Afvallen

risk, but n-6 PUFAs may compete with n-3 PUFA metabolism and attenuate benefits. n-3 PUFAs from both seafood and plant sources may reduce CHD risk, with little apparent influence from background n-6 PUFA intake. Plant-based n-3 PUFAs may particularly reduce CHD risk when seafood-based n-3 PUFA intake is low, which has implications for populations with low consumption or availability of fatty fish

Download Deel IV: De Nota Overgwicht schiet tekort - “Meer van het zelfde beleid” onverstandig- VWS Nota overgewicht 23 maart 2009
De oorzaak van overgewicht op individueel niveau lijkt simpel, want het is een gevolg van een positieve energiebalans: te veel eten en/of te weinig bewegen. Hieruit voortgeredeneerd is ook de oplossing ‘eenvoudig’. Als mensen minder eten én meer bewegen, stopt vanzelf de toename van hun gewicht. Slechts in een klein deel (5 procent) van de gevallen zijn overgewicht en obesitas een bijverschijnsel van ziekte Steeds meer levensmiddelenfabrikanten maken gebruik van logo’s op de verpakking, zoals het ‘Ik Kies Bewust-logo’ of het ‘Gezonde Keuze Klavertje’. Dergelijke logo’s helpen consumenten om de gezondere keuze binnen één productgroep te maken. Uniformiteit en wetenschappelijke onderbouwing van de gehanteerde criteria zijn belangrijk. De afgifte van het logo dient op dat punt transparant te zijn - Bos MB, de Vries JH, Wolffenbuttel BH, Verhagen H, Hillege JL, Feskens EJ. Ned Tijdschr Geneeskd. 2007 Oct 27;151(43):2382-8. The prevalence of the metabolic syndrome in the Netherlands: increased risk of cardiovascular diseases and diabetes mellitus type 2 in one quarter of persons under 60
Approximately 1 million Dutch adults below 60 years of age had the metabolic syndrome in the 1990's. Based on the total prevalence of the metabolic syndrome and hypercholesterolaemia, one quarter of the Dutch population younger then 60 runs an increased risk of cardiovascular disease and type 2 diabetes mellitus. - Bentley-Lewis R, Koruda K, Seely EW.

The metabolic syndrome associated with abdominal obesity, which includes insulin resistance, dyslipidemia, and elevated CRP levels, identifies subjects who have an increase in cardiovascular morbidity and mortality. Twenty to 25% of the adult population in the United States have the metabolic syndrome, and in some older groups this prevalence approaches 50%. - RIVM Bijna 2,5 miljoen ouderen in 2009
Op 1 januari 2009 telde Nederland bijna 2,5 miljoen ouderen (personen van 65 jaar en ouder). Daarmee was 15% van de bevolking 65-plusser. Van alle 65-plussers was 26% 80 jaar en ouder. Van alle 65-plussers was ruim 1,0 miljoen man (43%) en 1,4 miljoen vrouw (57%). Hoe hoger de leeftijd, hoe groter het aandeel vrouwen in de bevolking.

The metabolic syndrome (also known as dysmetabolic syndrome, MetS, Reaven syndrome, syndrome X, and insulin-resistance syndrome) is a well-recognized and all-too-frequently encountered fact of modern life, with staggering economic consequences. - Cornier MA, Dabelea D, Hernandez TL, Lindstrom RC, Steig AJ, Stob NR, Van Pelt RE, Wang H, Eckel RH. Endocr Rev. 2008 Dec;29(7):777-822. The metabolic syndrome
The "metabolic syndrome" (MetS) is a clustering of components that reflect overnutrition, sedentary lifestyles, and resultant excess adiposity. The MetS includes the clustering of abdominal obesity, insulin resistance, dyslipidemia, and elevated blood pressure and is associated with other comorbidities including the prothrombotic state, proinflammatory state, nonalcoholic fatty liver disease, and reproductive disorders. - Shanik MH, Xu Y, Skrha J, Dankner R, Zick Y, Roth J. Diabetes Care. 2008 Feb;31 Suppl 2:S262-8 Insulin resistance and hyperinsulinemia: is hyperinsulinemia the cart or the horse?
The condition exists when insulin levels are higher than expected relative to the level of glucose. Thus, insulin resistance is by definition tethered to hyperinsulinemia. - Del Prato S. Presse Med. 1992 Sep 9;21(28):1312-7. Hyperinsulinism. Causes and mechanisms
A high plasma insulin concentration in the presence of a normal or high plasma glucose level appears to be a common feature of glucose intolerance, obesity, and hypertension. - Vogeser M, König D, Frey I, Predel HG, Parhofer KG, Berg A.

HOMA-IR index (homeostasis model of insulin resistance) was calculated as [fasting serum glucose*fasting serum insulin/22.5], with lower values indicating a higher degree of insulin sensitivity. Individual changes in the carbohydrate metabolism achieved by a lifestyle intervention program were displayed by fasting serum insulin concentrations and the HOMA-IR but not by fasting glucose measurement alone. - Geloneze B, Tambascia MA. Arq Bras Endocrinol Metabol. 2006 Apr;50(2):208-15. Epub 2006 May 23 Laboratorial evaluation and diagnosis of insulin resistance
HOMA is a mathematical model that predicts IS simply by measuring insulinemia and fasting blood glucose and shows good correlation with hyperinsulinemic-euglycemic clamp method, considered a gold standard in the measurement of IS. - 33 Zimmet PZ. Diabetes Care. 1993 Dec;16 Suppl 3:56-70 Hyperinsulinemia--how innocent a bystander?
Epidemiological data support a key role for hyperinsulinemia in these disorders but it is far from conclusive except for the fact that hyperinsulinemia and insulin resistance may be present many years before the onset of impaired glucose tolerance and NIDDM, and clearly play a role in their etiology. - Sharma MD, Garber AJ. Curr Diab Rep. 2009 Oct;9(5):335-41 What is the best treatment for prediabetes?
Worldwide, along with the increasing prevalence of obesity, the number of people with prediabetes is increasing. The treatment approach is twofold: glycemic control and control of cardiovascular risk factors, mainly hypertension and hyperlipidemia. Intensive lifestyle modification is the mainstay of treatment in low-risk patients. - Fonseca VA. Clin Cornerstone. 2008;9(2):51-9; discussion 60-1. Identification and treatment of prediabetes to prevent progression to type 2 diabetes
Overt type 2 diabetes is usually preceded by a condition known as prediabetes, which is characterized by impaired fasting glucose (IFG) and impaired glucose tolerance (IGT). Both IFG and IGT exhibit elevated glucose levels that are not sufficient to be classified as diabetes but that represent the development of insulin resistance. Achieving glycemic control in patients with prediabetes through lifestyle and pharmacologic interventions can effectively prevent or delay the development of diabetes and its associated complications. - Martini LA, Wood RJ. Nutr Rev. 2006 Nov;64(11):479-86 Vitamin D status and the metabolic syndrome
The identification of vitamin D receptor expression in different tissues suggests a widespread role for vitamin D action beyond its classical function in bone and mineral metabolism. Recently, the importance of vitamin D status as a risk factor in the development of metabolic syndrome has been the focus of several studies. - Chiu KC, Chu A, Go VL, Saad MF. Am J Clin Nutr. 2004 May;79(5):820-5 Hypovitaminosis D is associated with insulin resistance and beta cell dysfunction

J Am Coll Nutr. 2001 Apr;20(2 Suppl):97-105 High-energy diets, fatty acids and endothelial cell function: implications for atherosclerosis
Our studies suggest that omega-6 fatty acids, and especially linoleic acid, cause endothelial cell dysfunction most markedly as well as can potentiate TNF-mediated endothelial cell injury. We propose that high-energy diets, and especially diets rich in linoleic acid, are atherogenic by contributing to an imbalance in cellular oxidative stress/antioxidant status of the endothelium, which can lead to activation of oxidative stress-responsive transcription factors, inflammatory cytokine production and the expression of adhesion molecules - Fedor D, Kelley DS. Curr Opin Clin Nutr Metab Care. 2009 Mar;12(2):138-46 Prevention of insulin resistance by n-3 polyunsaturated fatty acids
n-3 PUFA supplementation has clinical significance in the prevention and reversal of insulin resistance.

human beings evolved on a diet with a ratio of omega-6 to omega-3 essential fatty acids (EFA) of approximately 1 whereas in Western diets the ratio is 15/1 to 16.7/1. A high omega-6/omega-3 ratio, as is found in today's Western diets, promotes the pathogenesis of many diseases, including cardiovascular disease, cancer, osteoporosis, and inflammatory and autoimmune diseases, whereas increased levels of omega-3 polyunsaturated fatty acids (PUFA) (a lower omega-6/omega-3 ratio), exert suppressive effects. - Simopoulos AP.

The data suggest that the early (intrauterine/perinatal) exposure to hydrogenated fat rich in trans fatty acids programmed the hypothalamic feeding control mechanisms. As young adults, only trans-control animals showed loss of insulin-induced hypophagia, indicating that the mismatch between early and later nutritional environments was relevant. However, the trans group also showed signs of altered appetite signaling mechanisms, suggesting that the early adaptations may have deleterious consequences later in life. - Gezondheidsraad Richtlijnen goede voeding 2006

J Am Coll Nutr. 2002 Aug;21(4):298-306 Intake of refined carbohydrates and whole grain foods in relation to risk of type 2 diabetes mellitus and coronary heart disease
These data are consistent with results from recent metabolic experiments, suggesting favorable lipid profiles and glycemic control associated with higher intake of whole grains, but not with refined grains. It seems prudent, therefore, to distinguish whole-grain rather than refined-grain cereal products for the prevention of chronic diseases. - Murtaugh MA, Jacobs DR Jr, Jacob B, Steffen LM, Marquart L. Proc Nutr Soc. 2003 Feb;62(1):143-9 Epidemiological support for the protection of whole grains against diabetes
Intake of wholegrain foods may reduce diabetes risk. Three prospective studies in 160000 men and women examined the relationship of whole-grain or cereal-fibre intake with the risk of type 2 diabetes. Risk for incident type 2 diabetes was 21-27% lower for those in the highest quintile of whole-grain intake, and 30-36% lower in the highest quintile of cereal-fibre intake, each compared with the lowest quintile. - sensitivity: evidence from observational studies
Observational studies have found that diets rich in whole-grain foods are associated with improved insulin sensitivity. The improved insulin sensitivity may be mediated in part by magnesium and dietary fiber, two nutrients found in whole-grain foods. By incorporating whole-grain foods into the diet, therefore, insulin sensitivity might be improved - Liese AD, Roach AK, Sparks KC, Marquart L, D'Agostino RB Jr, Mayer-Davis EJ. Am J Clin Nutr. 2003 Nov;78(5):965-71 Whole-grain intake and insulin sensitivity: the Insulin Resistance Atherosclerosis Study

Voedingsvezels zijn delen van planten die door de mens niet worden verteerd. Ze hebben een gunstige invloed op de gezondheid. Voor twee effecten bestaat overtuigend wetenschappelijk bewijs: voldoende inname leidt tot een betere darmwerking en beschermt tegen hartziekten. Op basis van deze kennis formuleert de Gezondheidsraad nu een nieuwe richtlijn voor de vezelconsumptie. Voor volwassenen luidt die: 3,4 gram voedingsvezel per megajoule (14 gram per 1000 kilocalorieën), wat neerkomt op 30 tot 40 gram per dag. Deze richtlijn betreft vezels die van nature voorkomen in voedingsmiddelen. Op dit moment komt negentig procent van de Nederlandse bevolking niet aan de hoeveelheid voedingsvezel die in de richtlijn is verwoord. - 2004 Rijksinstituut voor Volksgezondheid en Milieu, Bilthoven Ons eten gemeten Gezonde voeding en veilig voedsel in Nederland

Gestational diabetes occurs in 5 to 9 percent of pregnancies in the United States and is growing in prevalence. - Kaaja R, Rönnemaa T. Rev Diabet Stud. 2008 Winter;5(4):194-202. Gestational diabetes: pathogenesis and consequences to mother and offspring
Data from Western countries suggest that the prevalence of GDM is increasing, being almost 10% of pregnancies and probably reflecting the global obesity epidemic. The majority of women with GDM seem to have beta-cell dysfunction that appears on a background of chronic insulin resistance already present before pregnancy. Because the oral glucose tolerance test (OGTT) is restricted to high risk individuals, 40% of GDM cases are left undiagnosed. After delivery, women with GDM and their offspring have an increased risk for developing the metabolic syndrome and type 2 diabetes. Thus, pregnancy may act as a "stress test", revealing a woman's predisposition to T2D and providing opportunities for focused prevention of important chronic diseases. - Jovanovic-Peterson L, Peterson CM. J Am Coll Nutr. 1996 Feb;15(1):14-20 Vitamin and mineral deficiencies which may predispose to glucose intolerance of pregnancy
Gestational diabetes is associated with excessive nutrient losses due to glycosuria. Specific nutrient deficiencies of chromium, magnesium, potassium and pyridoxine may potentiate the tendency towards hyperglycemia in gestational diabetic women because each of these four deficiencies causes impairment of pancreatic insulin production - Kleefstra N, Bilo HJ, Bakker SJ, Houweling ST., Ned Tijdschr Geneeskd. 2004 Jan 31;148(5):217-20., Chromium and insulin resistance
Since as early as the 50s of the last century, it has been known that chromium is essential for normal glucose metabolism. Too little chromium in the diet may lead to insulin resistance - Chaudhary DP, Sharma R, Bansal DD. Biol Trace Elem Res. 2009 Jul 24. Implications of Magnesium Deficiency in Type 2 Diabetes: A Review
Chronic magnesium deficiency has been associated with the development of insulin resistance. The present review discusses the implications of magnesium deficiency in type 2 diabetes. - Anderson RA. Clin Physiol Biochem. 1986;4(1):31-41. Chromium metabolism and its role in disease processes in man
Insufficient dietary Cr has been linked to maturity-onset diabetes and cardiovascular diseases. The dietary Cr intake of most individuals is considerably less than the suggested safe and adequate intake. Consumption of refined foods, including simple sugars, exacerbates the problem of insufficient dietary Cr since these foods are not only low in dietary Cr but also enhance additional Cr losses. Chromium losses are also increased due to pregnancy, strenuous exercise, infection, physical trauma and other forms of stress - Kumpulainen JT. Biol Trace Elem Res. 1992 Jan-Mar;32:9-18 Chromium content of foods and diets.
In many developing countries, such as Brazil, the Sudan, and Iran, the dietary intake is high, from 50-100 micrograms/d, whereas in certain developed countries, such as Finland, Sweden, Switzerland, and the US, the intake is 50 micrograms/d or lower and, consequently, at or below the estimated safe and adequate daily dietary intake range of 50-200 micrograms/d established by the US National Academy of Sciences. The average Cr content of human milk is below 0.5 micrograms/L, thus resulting in a very low average intake of 0.3 microgram Cr/d by exclusively breast-fed infants in the US and Finland. - Van Cauwenbergh R, Hendrix P, Robberecht H, Deelstra HA. Z Lebensm Unters Forsch. 1996 Sep;203(3):203-6 Daily dietary chromium intake in Belgium, using duplicate portion sampling.
Daily dietary chromium intake in Belgium has been evaluated by sampling duplicate portions of food, heating them at an acidic pH in a microwave oven and then quantifying the chromium by atomic absorption spectrometry. The mean intake value (53 +/- 31 micrograms/day) is similar to levels found for most other countries and is situated at the lower end of the recommended range for a safe and adequate daily dietary intake. - Preuss HG, Anderson RA. Curr Opin Clin Nutr Metab Care. 1998 Nov;1(6):509-12 Chromium update: examining recent literature 1997-1998
adequate daily dietary intake, which is set at 50-200 micrograms per day. Insufficient chromium intake is associated with signs and symptoms similar to those seen in diabetes and cardiovascular diseases. - Anderson RA. Regul Toxicol Pharmacol. 1997 Aug;26(1 Pt 2):S35-41 Chromium as an essential nutrient for humans
Chromium is an essential nutrient required for sugar and fat metabolism. Normal dietary intake of Cr for humans is suboptimal. The estimated safe and adequate daily dietary intake for Cr is 50 to 200 microg. However, most diets contain less than 60% of the minimum suggested intake of 50 microg. Insufficient dietary intake of Cr leads to signs and symptoms that are similar to those observed for diabetes and cardiovascular diseases. Supplemental Cr given to people with impaired glucose tolerance or diabetes leads to improved blood glucose, insulin, and lipid variables. - Rylander R. J Cardiovasc Risk. 1996 Feb;3(1):4-10. Environmental magnesium deficiency as a cardiovascular risk factor.
Through changes in the treatment of foodstuffs and altered diets, as well as increased use of surface water with low magnesium content, magnesium deficiency is present in modern society. Magnesium deficiency causes cardiac arrhythmia and several studies suggest that a low level of magnesium in drinking water is a risk factor for myocardial infarction, particularly among men. Before general prevention programmes can be recommended, risk groups must be defined and experimental intervention programmes performed. - Abdulla M, Behbehani A, Dashti H. Biol Trace Elem Res. 1989 Jul-Sep;21:173-8 Dietary intake and bioavailability of trace elements
The results indicate that the intake of potassium, magnesium, zinc, copper, and selenium is low when compared with the present recommended dietary allowance (RDA) values. - Marier JR. Magnesium. 1986;5(1):1-8 Magnesium content of the food supply in the modern-day world
A large-scale US survey has shown that the dietary magnesium intake tends to be lower than recommended. The suboptimal intake prevalent among US adults is consistent with the pattern observed in other North American and European surveys. - Ford ES, Li C, McGuire LC, Mokdad AH, Liu S., Obesity (Silver Spring). 2007 May;15(5):1139-46., Intake of dietary magnesium and the prevalence of the metabolic syndrome among U.S. adults

Int J Gynaecol Obstet. 2009 Mar;104 Suppl 1:S25-6 Future risk of diabetes in mother and child after gestational diabetes mellitus
Gestational diabetes mellitus (GDM) is a common pregnancy complication with increased maternal and perinatal morbidity. However, significant long-term morbidity also exists for the mother and offspring. Women with previous GDM have a very high risk of developing overt diabetes, primarily type 2 diabetes, later in life. Moreover, the risk of the metabolic syndrome is increased 3-fold in these women. Their offspring have an 8-fold risk of diabetes/prediabetes at 19-27 years of age. Thus, GDM is part of a vicious circle which increases the development of diabetes in the coming generations - Clausen TD, Mathiesen ER, Hansen T, Pedersen O, Jensen DM, Lauenborg J, Damm P. Diabetes Care. 2008 Feb;31(2):340-6. High prevalence of type 2 diabetes and pre-diabetes in adult offspring of women with gestational diabetes mellitus or type 1 diabetes: the role of intrauterine hyperglycemia
A hyperglycemic intrauterine environment appears to be involved in the pathogenesis of type 2 diabetes/pre-diabetes in adult offspring of primarily Caucasian women with either diet-treated GDM or type 1 diabetes during pregnancy. - Sobngwi E, Boudou P, Mauvais-Jarvis F, Leblanc H, Velho G, Vexiau P, Porcher R, Hadjadj S, Pratley R, Tataranni PA, Calvo F, Gautier JF. Lancet. 2003 May 31;361(9372):1861-5 Effect of a diabetic environment in utero on predisposition to type 2 diabetes

Thus, fetal exposure to maternal diabetes may contribute to the worldwide diabetes epidemic. Public health interventions targeting high-risk populations should focus on long-term follow-up of subjects who have been exposed in utero to a diabetic environment and on a better glycemic control during pregnancy. - Scientific American, You have to eat everything on your plate (Movie)

The potential relevance of different components of human milk for the observed reduction in the risk for overweight and obesity is discussed. The preventive effect of breast-feeding on overweight and obesity is an important additional argument for the promotion of breast-feeding in industrialised countries. - Singhal A. Nestle Nutr Workshop Ser Pediatr Program. 2007;60:15-25Does breastfeeding protect from growth acceleration and later obesity?
Nutrition in infancy has been suggested to have a major influence or program the long-term tendency to obesity. Breastfeeding, in particular, appears to protect against the development of later obesity, a conclusion supported by data from four systematic reviews and evidence that a longer duration of breastfeeding has greater protective effects. The size of the effect (up to a 20% reduction in obesity risk) although modest has important implications for public health. - Koubaa AA, Abed NB, Cheikhrouhou H, Dahmen H, Askri M, Ouerfelli N, Hasni K. Tunis Med. 2008 Jan;86(1):38-42. Protective effect of breast feeding in childhood obesity
Promotion of the breast-feeding and information on its methods and its control are a public health priority, it protects the child and his mother from certain diseases and prevents from childhood obesity. OMS recommends an exclusive breast feeding until the 6 months age, and to continue if possible until the 2 years. - Binns C, Lee MK, Oddy W. Asia Pac J Public Health. 2003;15 Suppl:S22-6 Breastfeeding and the prevention of obesity
Obesity will be the greatest challenge for nutrition and is probably the greatest overall challenge to public health facing us in the next few decades. Being overweight or obese is a risk factor for many chronic diseases and the impact on wellbeing and mortality is well documented. Breastfeeding exclusively to six months of age is the most appropriate way to feed infants. A review of the international literature and an analysis of Australian data support the hypothesis that breastfeeding reduces the prevalence of obesity. Breastfeeding promotion should become a part of public health programmes for the prevention of obesity. - RIVM Wat zijn de mogelijke gezondheidsgevolgen van borstvoeding?
Borstvoeding is de beste voeding als het gaat om de gezondheid van de baby. Ook voor de moeder zijn er positieve gezondheidseffecten als zij borstvoeding geeft. Bij kinderen die zes maanden uitsluitend borstvoeding kregen, komt overgewicht (tussen 3 en 10 jaar) en hoge bloeddruk minder vaak voor. - RIVM Voeding van zuigelingen en peuters
In april 2006 heeft de WHO nieuwe internationaal toepasbare groeistandaarden voor zuigelingen en jonge kinderen gepubliceerd. Voor het vaststellen van deze groeistandaarden is het uitgangspunt dat borstvoeding de norm is en dat het kind dat borstvoeding krijgt de standaard is voor het meten van een gezonde groei. Bij de invoering van het elektronisch kinddossier JGZ worden deze standaarden zo snel mogelijk voor de Nederlandse situatie geïmplementeerd. Een afvlakking van de curve van een borstgevoed kind rond de leeftijd van drie à vier maanden hoeft dus op zich geen aanleiding te vormen voor specifieke maatregelen, zoals vroeger starten met vaste voeding of aanvulling met kunstvoeding - The WHO Child Growth Standards
The following documents describe the sample and methods used to construct the standards and present the final charts. - RIVM Ruim 80% begint met borstvoeden maar groot deel stopt ook weer snel
Ruim 80% van de moeders begint direct na de geboorte met het geven van borstvoeding. De kans dat een hoogopgeleide vrouw start met het geven van borstvoeding is groter dan die van een laagopgeleide vrouw. Het percentage zuigelingen dat op de leeftijd van drie maanden echter nog steeds uitsluitend borstvoeding krijgt, is veel lager (30%). In nog sterkere mate geldt dit voor het percentage zuigelingen van vijf maanden (23%). Wel lijkt het er op dat het percentage zuigelingen dat uitsluitend borstvoeding krijgt op de eerste dag, na drie maanden en na zes maanden, de laatste jaren iets is gestegen. In vergelijking met de rest van Europa geven in Nederland relatief weinig moeders borstvoeding - Daniels SR. Future Child. 2006 Spring;16(1):47-67 The consequences of childhood overweight and obesity
Daniels notes that the possibility has even been raised that the increasing prevalence and severity of childhood obesity may reverse the modern era's steady increase in life expectancy, with today's youth on average living less healthy and ultimately shorter lives than their parents-the first such reversal in lifespan in modern history. Such a possibility, he concludes, makes obesity in children an issue of utmost public health concern - Mackenbach JP. Ned Tijdschr Geneeskd. 2005 Nov 12;149(46):2550-3 On Hendrikje van Andel-Schipper and other remarkable developments in the life expectancy of the Dutch population
Based on an extrapolation of recent trends in cause-specific mortality, Netherlands Statistics predicts an increase in life expectancy of 2 to 3 years in the half-century between 2004 and 2050. Experts are deeply divided about the prospects for further increases in life expectancy. Some have argued that such estimates are too optimistic because, for example, the obesity epidemic might even reduce average life expectancy in the future - Blacklow RS. Am J Clin Nutr. 2007 Nov;86(5):1560S-2S. Actuarially speaking: an overview of life expectancy. What can we anticipate?
Predictions for the continuing lengthening of the life span of the class of 2005 and succeeding classes may be jeopardized by the alarming increase in obesity, which worsens the incidence of cardiovascular disorders and cancer, the 2 leading causes of death at this time, as well as of diabetes, musculoskeletal disorders, and other categories of disease. - Fontaine KR, Redden DT, Wang C, Westfall AO, Allison DB.

These results show that a positive correlation of 25(OH) vitamin D concentrations with insulin sensitivity and vitamin D deficiency could be a confirmative sign of insulin resistance - Zhang C, Qiu C, Hu FB, David RM, van Dam RM, Bralley A, Williams MA. PLoS One. 2008;3(11):e3753 Maternal plasma 25-hydroxyvitamin D concentrations and the risk for gestational diabetes mellitus
Findings from the present study suggest that maternal vitamin D deficiency in early pregnancy is significantly associated with an elevated risk for GDM. - Lapillonne A. Med Hypotheses. 2010 Jan;74(1):71-5 Vitamin D deficiency during pregnancy may impair maternal and fetal outcomes
It appears that vitamin D insufficiency during pregnancy is potentially associated with increased risk of preeclampsia, insulin resistance and gestational diabetes mellitus. Furthermore, experimental data also anticipate that vitamin D sufficiency is critical for fetal development, and especially for fetal brain development and immunological functions. Vitamin D deficiency during pregnancy may, therefore, not only impair maternal skeletal preservation and fetal skeletal formation but also be vital to the fetal "imprinting" that may affect chronic disease susceptibility soon after birth as well as later in life. - Holmes VA, Barnes MS, Alexander HD, McFaul P, Wallace JM. Br J Nutr. 2009 Sep;102(6):876-81 Vitamin D deficiency and insufficiency in pregnant women: a longitudinal study
Given the potential consequences of hypovitaminosis D on health outcomes, vitamin D supplementation, perhaps at higher doses than currently available, is needed to improve maternal vitamin D nutriture.
