SYNOPSES OF ARTICLES THIS MONTH
1. High protein/dairy, exercise, and low calories to lose fat weight - Weight loss can have substantial health benefits for overweight or obese persons; however, the ratio of fat:lean tissue loss may be more important. We aimed to determine how daily exercise (resistance and/or aerobic) and a hypoenergetic diet varying in protein and calcium content from dairy foods would affect the composition of weight lost in otherwise healthy, premenopausal, overweight, and obese women...Therefore, diet- and exercise-induced weight loss with higher protein and increased dairy product intakes promotes more favorable body composition changes in women characterized by greater total and visceral fat loss and lean mass gain.
2. Absolutely avoid trans-fats - Consumption of industrial trans fatty acids (iTFA) increases LDL cholesterol, decreases HDL cholesterol, and is strongly associated with a higher risk of cardiovascular disease (CVD).
3. A low glycemic index (LGI) diet reduces appetite - Postprandial glycemia, insulinemia, and subjective appetite ratings after a test meal were better after 10-wk ad libitum intake of a LGI compared to a HGI diet.
4. High polyunsat'd fat (PUFA)/low sat'd fat intake lowers blood pressure - Our study showed that FA composition in erythrocyte membranes is associated with the risk of hypertension in middle-aged and older women.
5. High glycemic load (sugary foods) diet increases risk of bacterial vaginosis - BV is the most frequent cause of vaginal complaints among reproductive-aged women and is characterized by an imbalance in the vaginal flora, with the replacement of Lactobacillus species by anaerobic bacteria and a corresponding increase in vaginal pH (>4.5). Nutrient rich high glycemic load foods increase risk of having this condition.
6. Global shift to Western diet increasing chronic disease
8. Advanced glycation endproducts (AGEs), prevented by antioxidants (vit. C and E), are associated with cardiovascular disease, diabetes, chronic kidney disease, and increased mortality. Serum AGE concentration is strongly increased by body fat.
9a. Poor children in US have weaker bones - These results are evidence that health disparities persist among 8- to 11-y-old, food-insecure boys. Successful interventions to improve diet and bone health and reduce food insecurity among children are a continuing need in the United States. 9b. Canadian Inuit also are food insecure - Nutrition transition and food insecurity are associated with a multifaceted shift in nutrient status and intakes with implications for increased risk of diet-sensitive chronic diseases.
10. Get enough (not too much) Selenium - Selenium (Se), in the form of selenoproteins, imparts many health benefits with antiinflammatory properties. A multivitamin/mineral or Brazil nut gives plenty.

Thoreau's three truths: "that this earth is a garden of delights; that the world crowds round the individual, leaving him no vista, and shuts out the beauty of the earth; and that the wholesome wants of man are few."
