Omega - 3 Fatty Acids And Menopause
Maintaining a proper balance of dietary fats may decrease the levels
of bone loss associated with post-menopausal osteoporosis, according to a recent study by scientists at Purdue University and the Indiana University School of Medicine. Estrogen deficiency, which is common in post-menopausal women, is a main contributor to bone loss. Research has found that diets with a low ratio of omega-6 fatty acids to omega-3 fatty acids can minimize this. Omega-6 fatty acids are typically found in foods such as grains and beef, while omega-3 fatty acids are found in foods such as walnuts and salmon. Several research studies have shown that omega-3 fatty acids help promote bone formation according to Bruce Watkins, professor and director of Purdue's Center for Enhancing Foods to Protect Health. That research also indicates that higher intakes of omega-6 fatty acids lead to an increased production of compounds associated with bone loss." The Journal of Nutritional Biochemistry discusses a current study that assesses bone mineral content and bone mineral density in female rats. These measurements are used as indicators of bone mass and bone strength, respectively. Half the rats in the study had their ovaries removed, which leads to a rapid drop in estrogen levels. This mimics menopause and is the standard model for studying compounds that alleviate osteoporosis, explains Mark Seifert, a professor of anatomy and cell biology at the Indiana University School of Medicine and the study's co-author. He also believes that studies like this will help researchers assess drugs or nutraceuticals that may reduce the bone loss that is induced by menopause. In the study, groups of these rats were fed diets containing different ratios of omega-6 to omega-3 polyunsaturated fatty acids. Although both types of fats are essential for human health, diets with a high ratio of omega-6 fatty acids to omega-3 fatty acids are often associated with cancer, cardiovascular disease, and inflammatory and autoimmune diseases. However, diets with a low ratio of omega-6 to omega-3 fatty acids are thought to promote cardiovascular health, improve http://www.dontplayplay.com/html/Bot...002/46883.html |
