DAIRY WEIGHT LOSS: http://www.nutrition.org/cgi/content/abstract/134/8/1905

Multiple regression with age, ethnicity, height, Tanner breast stage, physical activity, energy, soda, and calcium intake explained 17% of the variation in iliac skinfold thickness. Calcium intake, age, and physical activity were significantly negatively associated with iliac skinfold thickness whereas height,,,,Soda intake was significantly positively associated with weight in both models (P = 0.01, both models). Decreasing soda and increasing dairy consumption among Asians may help maintain body fat and weight during adolescence.

INTERPRETATION: Soda makes you fat, milk and exercise keep you thin.

DIABETES PREVENTION: http://www.ajcn.org/cgi/content/full/80/2/243

Studies such as the Diabetes Prevention Program have shown that intensive diet and exercise programs are not only highly effective in delaying or preventing the disease but are more cost-effective than even the cheapest drug. GL (glycemic load) is defined as the product of the carbohydrate content per serving of food and its GI (glycemic index). The findings of Schulze et al suggest that the quality of carbohydrate (ie, the GI) is important irrespective of its amount. However, the results also imply that a high GL is of little consequence in insulin-sensitive persons. Thus, a diet based on large amounts of carbohydrate from high-GI sources might be tolerated by insulin-sensitive persons but is excessively challenging to the ß cells of persons who are more insulin-resistant or predisposed to diabetes. A high carbohydrate intake from low-GI sources may well be superior in terms of increasing fat oxidation and improving overall glucose disposition (14). If this is the case, it might explain why the quality of carbohydrate (ie, GI) more often shows a significant association with disease risk (diabetes, heart disease, and cancer) than does the carbohydrate content or GL of the diet.

Weight management through lifestyle modification for the prevention and management of type 2 diabetes: rationale and strategies. A statement of the American Diabetes Association, the North American Association for the Study of Obesity, and the American Society for Clinical Nutrition

Am J Clin Nutr 2004 80: 257-263.

The American Diabetes Association, the North American Association for the Study of Obesity, and the American Society for Clinical Nutrition have joined together to issue this statement on the use of lifestyle modification in the prevention and management of type 2 diabetes.

TABLE 3 Dietary guidelines from the American Diabetes Association and the American Heart Association1

Consume a variety of fruit, vegetables, grains, low-fat or nonfat dairy products, fish, legumes, poultry, and lean meats

Limit foods high in saturated fat, trans fatty acids, and cholesterol; substitute with unsaturated fat from vegetables, fish, legumes, and nuts

Effects of cis-9,trans-11 conjugated linoleic acid supplementation on insulin sensitivity, lipid peroxidation, and proinflammatory markers in obese men1,2,3

Conclusions: A CLA preparation containing the purified c9,t11 CLA isomer increased insulin resistance and lipid peroxidation compared with placebo in obese men. Because c9,t11 CLA occurs in commercial supplements as well as in the diet, the present results should be confirmed in larger studies that also include women.

[In contrast] If anything, it seems as if a high intake of dairy products [which contain another isomer, not the one in commercial products] can protect against developing the metabolic syndrome.

Extra Virgin Olive Oil Biophenols Inhibit Cell-Mediated Oxidation of LDL by Increasing the mRNA Transcription of Glutathione-Related Enzymes; Roberta Masella et al, J. Nutr. 2004 134: 785-791

” It has been reported that oxidized LDL (oxLDL) are involvedin the pathogenesis of atherosclerosis, and that macrophagesas well as other cells of the arterial wall can oxidize LDLin vitro,… Our findings suggestthat the activation of mRNA transcription of GSH-related enzymesrepresents an important mechanism in phenolic antioxidativeaction.”

 

Trans Fatty Acids in Adipose Tissue and the Food Supply Are Associated with Myocardial Infarction; Peter M. Clifton, Jennifer B. Keogh, and Manny Noakes, J. Nutr. 2004 134: 874-879.

” Metabolic studies have clearly shown that trans fatty acids(TFAs) elevate LDL and lower HDL cholesterol…We conclude that TFAs in adipose tissue are associatedwith an increased risk of coronary artery disease and rapidlydisappear from adipose tissue when not included in margarines. “

Consumption of Foods Rich in Flavonoids Is Related to a Decreased Cardiovascular Risk in Apparently Healthy French Women; Louise I. Mennen et al ; J. Nutr. 2004 134: 923-926

” A high consumption of flavonoids may lower cardiovascular riskthrough their antioxidant capacity. This study evaluated therelation between consumption of foods rich in flavonoids andestimated cardiovascular risk…These results indicate thatin women, a high consumption of flavonoid-rich foods may preventcardiovascular disease.”
