AJCN July, 2011 -DETAILS

AJCN FEATURE his month: 1. A calorie is not a calorie – gut microbiota represents an environmental regulator of fat storage by increasing absorption of monosaccharides from the gut and by promoting the deposition of lipid in adipocytes…bacteria from obese animals were able to extract more calories from the diet for their host. (Yogurt and other fermented foods provide good gut bacteria.)

2. Calcium SUPPLEMENTS increase the risk of kidney stones in postmenopausal women. Dietary calcium sources like cheese do not.

3. Obesity causes cardiovascular disease. Only 1/4 of Korean men are not overweight, whereas most women are not. Men have much higher prevalence of obesity-related cardiovascular risk factors, such as hypertension, diabetes mellitus, and dyslipidemia.

4. Obesity causes cardiovascular disease. Central fat mass stiffens arteries. In contrast, peripheral fat and lean masses may counteract such adverse effects.

5. A low-fat diet did not have adverse glycemic effects except in diabetics.

6. Fruits and vegetables reduce weight gain, meat and fried food increases weight gain.

7. High serum vitamin D is associated with weight loss – Low concentrations of circulating vitamin D are common with obesity and may represent a potential mechanism explaining the elevated risk of certain cancers and cardiovascular outcomes observed in individuals who are overweight or obese. Conclusion: A greater degree of weight loss, achieved through either a reduced-calorie diet or increased exercise, is associated with increased circulating 25(OH)D concentrations.

8. Obese mothers are likely to cause obese children. In a study of 200,000 pregnancies, the weight of children of normal weight mothers is controlled by genetics and environment. The weight of children of obese mothers is effected by intrauterine mechanisms, causing their kids to be more obese.

9. Another reason to stop smoking – Our findings suggest that direct intrauterine exposure to smoke until late pregnancy leads to different height and weight growth adaptations and increased risks of overweight and obesity in preschool children.

10. Factors other than protein intake explain why older people have lower muscle protein synthesis – So get exercise!

11. Serum Vitamin D levels are inversely related to weight gain and heart disease risk – Higher serum 25(OH)D concentrations may be inversely associated with adiposity, triglycerides, triglyceride:HDL-cholesterol ratio, and metabolic syndrome but are not associated with LDL and HDL cholesterol, insulin, glucose, HOMA-IR, or HOMA-β in postmenopausal women.

12. Coffee does not increase heart disease risk – Consumption of filtered caffeinated coffee was not associated with cardiovascular disease (CVD) or all-cause mortality in women with CVD.

13. Based on vitamin D level, children in lower third need supplements – In children, given the negative outcomes associated with poor vitamin D status and metabolic syndrome (MetSyn), consideration of vitamin D supplementation in reversing cardiometabolic risk factors appears to be warranted.

14. Yogurt, not milk or cheese, preserves carotid artery – Elevated common carotid artery intima-media thickness (CCA-IMT) has been shown to be predictive of stroke, coronary deaths, and coronary events, including myocardial infarction. Conclusion: Increased consumption of yogurt, but not of other dairy products, is associated with a lower CCA-IMT, independent of other risk factors.

15. Fruits and veggies, esp. cruciferous veggies, reduce rcardiovascular disease and increase lifespan – In 134,000 women, authors identified 3442 deaths among women during a mean follow-up of 10.2 y and 1951 deaths among men during a mean follow-up of 4.6 y. Overall, fruit and vegetable intake was inversely associated with risk of total mortality in both women and men, and a dose-response pattern was particularly evident for cruciferous vegetable intake.

16. The home is a privileged environment that nurtures healthy eating and in which healthier food choices trigger and are triggered by more positive emotions.

17. B vitamins and fish oil improve recovery of mental function after a stroke

The best thing for being sad is to learn something. That is the only thing that never fails That is the only thing which the mind can never exhaust, never be tortured by, never fear…never dream of regretting. – Merlyn, to King Arthur
