More reasons to cut back on saturated fats " … too much saturated fat may be problematic, even if your cholesterol isn’t high, because of its possible effects on insulin functions, potentially raising the risk of diabetes, cancer, ovarian disorders and other health problems."

New Guidelines Issued for Beverage Classification and Consumption "On the basis of caloric and nutrient contents and related health benefits and risks, the panel ranked beverages from the lowest to the highest value. To fulfill daily water needs, drinking water was ranked as the preferred beverage, followed in decreasing value by tea and coffee, low-fat (1.5% or 1.0%) and skim (nonfat) milk and soy beverages, noncalorically sweetened beverages, beverages with some nutritional benefits (fruit and vegetable juices, whole milk, alcohol, and sports drinks), and calorically sweetened, nutrient-poor beverages. 'The Panel recommends that the consumption of beverages with no or few calories should take precedence over the consumption of beverages with more calories,' the authors write. 'Potable water could be used to fulfill almost all the fluid needs of healthy individuals. However, to allow for variety and individual preferences, healthful diets may include several other types of beverages.'

Salad eaters have higher levels of key nutrients "People who eat plenty of salads, or raw vegetables in general, typically have higher blood levels of several important nutrients, according to a large study of U.S. adults. Researchers found that even one serving of raw vegetables a day moved people closer to getting the recommended amounts of vitamins A, E, B6 and folic acid. And as salad and raw vegetable intake increased, so did blood levels of vitamins C and E, folic acid and several carotenoids -- antioxidants that give yellow, orange and red hues to many vegetables and fruits. "

Survey: Americans fuzzy on biotech foods "In the five years since Pew began plumbing American attitudes toward genetically engineered food, U.S. acreage in such crops has grown substantially. Today, 89% of soybeans, 83% of cotton and 61% of corn is genetically engineered to resist weed-killing chemicals or to help the plants make their own insecticides. Because most processed foods contain at least small amounts of soy lecithin, corn syrup or related ingredients, almost everyone in the United States has consumed some amount of gene-altered food."

Definition of Trans fat "Trans fat: An unhealthy substance, also known as trans fatty acid, made through the chemical process of hydrogenation of oils. Hydrogenation solidifies liquid oils and increases the shelf life and the flavor stability of oils and foods that contain them.… In the realm of dietary dangers, trans fats rank very high. It has been estimated that trans fats are responsible for some 30,000 early deaths a year in the United States. Worldwide the toll of premature deaths is in the millions."

Fruit and vegetable intakes and bone mineral status: a cross sectional study in 5 age and sex cohorts. (Am J Clin Nutr. 2006) "CONCLUSIONS: Higher fruit and vegetable intakes may have positive effects on bone mineral status in both younger and older age groups, especially at the spine and femoral neck. The specific mechanisms remain to be ascertained, but vitamin C, other fruit-specific antioxidants, and lifestyle may play a role."

Relationship and Interaction between Sodium and Potassium. (J Am Coll Nutr. 2006) "Compared with the Stone Age diet, the modern human diet is both excessive in NaCl and deficient in fruits and vegetables which are rich in K(+) and HCO(3)(-)-yielding organates like citrate. With the modern diet, the K(+)/Na(+) ratio and the HCO(3)(-)/Cl(-) ratio have both become reversed. Yet, the biologic machinery that evolved to process these dietary electrolytes remains largely unchanged, genetically fixed in Paleolithic time. Thus, the electrolytic mix of the modern diet is profoundly mismatched to its processing machinery. Dietary potassium modulates both the pressor and hypercalciuric effects of the modern dietary excess of NaCl. A marginally deficient dietary intake of potassium amplifies both of these effects, and both effects are dose-dependently attenuated and may be abolished either with dietary potassium or supplemental KHCO(3)."

Scientific evidence of interventions using the Mediterranean diet: a systematic review. (Nutr Rev. 2006)

The Mediterranean diet: science and practice. (Public Health Nutr. 2006) "Epidemiologic evidence has also supported beneficial effects of higher intakes of fruits and vegetables, whole grains, fish, and daily consumption of moderate amounts of alcohol. Together with regular physical activity and not smoking, our analyses suggest that over 80% of coronary heart disease, 70% of stroke, and 90% of type 2 diabetes can be avoided by healthy food choices that are consistent with the traditional Mediterranean diet.Conclusion: Both epidemiologic and metabolic studies suggest that individuals can benefit greatly by adopting elements of Mediterranean diets."
