Doctors agree that vitamin D promotes bone health, but a belief that it can also prevent cancer, cardiovascular disease and other causes of death has been a major health controversy. Consistent with advice issued last fall by the Institute of Medicine, a new study finds that vitamin D did not confer benefits against mortality in postmenopausal women after controlling for key health factors such as abdominal obesity. http://medicalxpress.com/news/2011-11-vitamin-d-mortality-benefit-older.html Health Tue, 01 Nov 2011 10:13:54 EST news239361203 New research, led by psychologists at the University of Bristol, has found that children who are familiar with a snack food will expect it to be more filling. This finding, published (online ahead of print) in the American Journal of Clinical Nutrition, is important because it reveals one way in which children over-consume snack foods and increase their risk of becoming overweight. http://medicalxpress.com/news/2011-10-familiarity-fullness-children-snack-foods.html Health Mon, 03 Oct 2011 09:52:28 EST news236854334 Developing healthy habits like drinking milk as a teen could have a long-term effect on a woman's risk for type 2 diabetes, according to new research in this month's issue of the American Journal of Clinical Nutrition (1). Researchers found that milk-drinking teens, were also likely to be milk-drinking adults – a lifelong habit that was associated with a 43 percent lower risk for type 2 diabetes compared to non-milk drinkers. Diabetes affects more than 25.8 million people, or nearly 1 out of 10 Americans. http://medicalxpress.com/news/2011-09-milk-drinking-teens-reap-health-benefits.html Addiction Wed, 14 Sep 2011 09:22:55 EST news235210959 Results of a large study among older women suggest that those who ate more of the "sunshine vitamin" were less likely to experience depression symptoms than women who consumed less of the vitamin, according to findings published this week by Elizabeth Bertone-Johnson at the University of Massachusetts Amherst School of Public Health and Health Sciences, with colleagues from several other U.S. academic centers. http://medicalxpress.com/news/2011-08-vitamin-d-foods-depression-older.html Health Fri, 26 Aug 2011 07:08:57 EST news233561226 Physical activity requires strong, healthy muscles. Fortunately, when people exercise on a regular basis, their muscles experience a continuous cycle of muscle breakdown (during exercise) and compensatory remodeling and growth (especially with weightlifting). Athletes have long experimented with methods to augment these physiologic responses to enhance muscle growth. One such ergogenic aid that has gained recent popularity is the use of high-quality, high-protein beverages during and after exercise, with dairy-based drinks enriched with whey proteins often taking front stage. Many studies have documented a beneficial effect of their consumption. Of particular interest is the effect of the essential amino acid leucine contained in these products. Two papers, published in the September 2011 issue of The American Journal of Clinical Nutrition, report the results of 2 independent studies conducted to understand better how amino acids influence protein synthesis in recreational athletes. http://medicalxpress.com/news/2011-08-muscle-building-effect-protein-beverages-athletes.html Other Thu, 18 Aug 2011 13:38:21 EST news232893488 Can a cozy dining table and nice music prompt people to reach for the greens and go light on dessert? http://medicalxpress.com/news/2011-07-home-healthy-meal.html Health Wed, 27 Jul 2011 15:30:01 EST news230999148 Variety is considered the "spice of life," but does today's unprecedented level of dietary variety help explain skyrocketing rates of obesity?

Recent studies have questioned the need to reduce the intake of saturated fatty acids in the diet and to increase that of polyunsaturated fatty acids. In an article in the British Journal of Nutrition based on a desk study, researchers of Wageningen University, part of Wageningen UR, clarify what is the best intake. A low intake of saturated and trans fatty acids, a minimum intake of 10 grams per day for women and 15 grams per day for men of the polyunsaturated fatty acid linoleic acid and a minimum intake of 250 mg per day of certain fish fatty acids give the best guarantee of a low risk of a heart attack. http://medicalxpress.com/news/2011-06-intake-fatty-acids-heart.html Health Thu, 30 Jun 2011 09:32:27 EST news228645094 Overweight or obese women with less-than-optimal levels of vitamin D who lose more than 15 percent of their body weight experience significant increases in circulating levels of this fat-soluble nutrient, according to a new study by researchers at Fred Hutchinson Cancer Research Center. http://medicalxpress.com/news/2011-05-percent-body-weight-significantly-boosts.html Overweight and Obesity Wed, 25 May 2011 16:11:41 EST news225558446 Investigators from the Slone Epidemiology Center at Boston University have reported that African American women who consumed a diet high in vegetables and fruit gained less weight over a 14-year period than those who consumed a diet high in red meat and fried foods. This is the first prospective study to show that a healthier diet is associated with less weight gain in African American women, a population with a high prevalence of obesity. The study results, published in the American Journal of Clinical Nutrition, were based on data from the Black Women's Health Study (BWHS), a large follow-up study of 59,000 African American women from across the U.S. conducted since 1995. http://medicalxpress.com/news/2011-05-diet-high-vegetables-fruit-weight.html Health Fri, 20 May 2011 11:20:20 EST news225109201 Folic acid does not reduce the risk of getting cardiovascular diseases, reports a three-year study of more than eight hundred people by Wageningen University.
