White button mushrooms appear to boost immune function It appears that a little fungus may be good for what ails you. That's the conclusion of a new study that found that eating white button mushrooms may boost the immune system and protect against infection. If the research, done on animals, translates to people, it could raise the health-benefit profile of the fungus, which also contains high concentrations of the super-antioxidant ergothioneine, which protects cells from damaging free radicals. "This is the first published study showing the effect of white button mushrooms on immune function," Dayong Wu, a scientist in the Immunology Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts and lead author of the study, published in the June issue of the Journal of Nutrition, told NutraIngredients.com. The research also suggests that the mushroom may boost both innate and acquired immune system health. The innate immune system, the one you're born with, is the body's first line of defense. The acquired immune system revs up if a pathogen makes its way past the innate system and customizes the immune response to target the invader.

Vitamin D3 and 25-hydroxyvitamin D3 in raw and cooked pork cuts. Ina Clausen, Jette Jakobsen, Torben Leth and Lars Ovesen. Journal of Food Composition and Analysis Volume 16, Issue 5, October 2003, Pages 575-585 doi:10.1016/S0889-1575(03)00064-4 Meat 25OHD3 contributes significantly to vitamin D activity. Food databases should include concentrations of both vitamin D and 25OHD.

Concentrations of vitamin D3 and 25-hydroxyvitamin D3 in raw and cooked New Zealand beef and lamb. Roger Purchas, Maggie Zoua, Philip Pearcea and Felicity Jackson- Journal of Food Composition and Analysis Volume 20, Issue 2, March 2007, Pages 90-98 For lamb, the highest levels of vitamin D3 were in the shoulder chop both before and after cooking, while levels were lowest in the rack muscle. Similar cut differences were shown for 25OHD3 concentrations. For beef there were no significant differences between the cuts for vitamin D3, but concentrations of 25OHD3 were lower in the striploin before and after cooking, Vitamin D3 levels tended to be higher in beef cuts than in lamb cuts, but the opposite held for 25OHD3. Concentrations of vitamin D3 were similar to those in other reports, but the 25OHD3 levels were at the high end of reported ranges. With 25OHD3 being more potent than vitamin D3, it is concluded that meat can make a useful contribution of this vitamin to the human diet.

Benefits of Vitamin D Supplementation Joel M. Kauffman, Ph.D. Journal of American Physicians and Surgeons Volume 14 Number 2 - Summer 2009 Clinical trials show that vitamin D supplementation at higher levels than previously recommended is beneficial for many conditions. It decreases the frequency of falls and fractures, helps prevent cardiovascular disease, and reduces symptoms of colds or influenza. Benefits are also seen in diabetes mellitus, multiple sclerosis, Crohn disease, pain, depression, and possibly autism. Sunlight does not cause an overdose of vitamin D production, and toxicity from supplementation is rare. Dose recommendations are increasing, but appear to be lagging the favorable trial results. A number of common drugs deplete vitamin D levels, and others may limit its biosynthesis from sunlight. People with adequate levels from sun exposure will not benefit from supplementation. While dietary intake is helpful, supplementation is better able to raise serum 25-hydroxyvitamin D , the major circulating metabolite, to the level now thought adequate, 30-50 ng/mL. Where there is inadequate daily sun exposure, oral doses of 1,000-2,000 IU/d are now considered routine, with much higher doses (up to 50,000 IU) for rapid repletion now considered safe.

"Good research is good for medicine. The only thing more important than good research is ethical research. The February 16th issue of the New England Journal of Medicine (NEJM) had a research paper on vitamin D and colon cancer. Was it good research? Was it ethical research? At stake are the lives of 36,000 older American women who agreed to participate in the Women's Health Initiative. "

Introduction: nutritional and functional roles of eggs in the diet. Applegate E. J Am Coll Nutr. 2000 Oct;19(5 Suppl):495S-498S. Review. PMID: 11022998 For years, eggs have been held up as a powerhouse of nutrition. This reputation has been due to eggs' exceptional nutrition profile as a nutrient-dense food containing high quality protein and a substantial amount of many essential vitamins and minerals. Unfortunately their position on the nutrition pedestal fell with the discovery that they are also a source of dietary cholesterol. The most recent scientific research not only returns eggs to their golden past, but elevates their position as a functional food and ultimately provides more reasons than ever to consume eggs. In February 2000, scientists convened at a conference in Amelia Island, Florida, to discuss the latest research about the role of eggs in disease prevention and the promotion of health. This supplement of the Journal of the American College of Nutrition (JACN) presents compelling scientific evidence about eggs' functional food attributes, reaffirms that eggs have a minimal effect on blood cholesterol levels and presents new research on the contribution of eggs to the American diet. For health professionals, this issue provides a new scientifically based viewpoint on eggs and their role in health and nutrition, a viewpoint that should be imparted to all consumers in an effort to ensure optimal health and well-being.

Separate effects of reduced carbohydrate intake and weight loss on atherogenic dyslipidemia -- Krauss et al. 83 (5): 1025 -- American Journal of Clinical Nutrition Changes in peak LDL diameter (Table 2) and mass concentrations of LDL subfractions (Table 3) induced by each of the diets were reflected by changes in the proportions of subjects exhibiting LDL subclass pattern B (Figure 2). There were linear reductions in the prevalence of pattern B as a function of reduced carbohydrate intake after both the stable-weight and weight-loss periods. However, the slopes of these relations differed (P = 0.04) such that the magnitude of the reduction in expression of pattern B induced by weight loss increased in association with the percentage of carbohydrate intake. Conclusions: Moderate carbohydrate restriction and weight loss provide equivalent but nonadditive approaches to improving atherogenic dyslipidemia. Moreover, beneficial lipid changes resulting from a reduced carbohydrate intake were not significant after weight loss. Separate effects of reduced carbohydrate intake and weight loss on atherogenic dyslipidemia. Krauss RM, Blanche PJ, Rawlings RS, Fernstrom HS, Williams PT. Am J Clin Nutr. 2006 May;83(5):1025-31; quiz 1205. Erratum in: Am J Clin Nutr. 2006 Sep;84(3):668. PMID: 16685042

"Eating tomatoes in your daily salad or regularly enjoying a healthy red sauce on your spaghetti could help reduce your risk of stroke, according to research published this week in the journal Neurology. Tomatoes contain a powerful antioxidant that is good for brain health, the researchers say, and cooked tomatoes seem to offer more protection than raw. "
