Fatty acid tied to depression and inflammation


Posted by AregM

The imbalance of fatty acids in the typical American diet could be associated with the sharp increase in heart disease and depression seen over the past century, a new study suggests. Specifically, the more omega-6 fatty acids people had in their blood compared with omega-3 fatty acid levels, the more likely they were to suffer from symptoms of depression and have higher blood levels of inflammation-promoting compounds, report Dr. Janice K. Kiecolt-Glaser and her colleagues from Ohio State University College of Medicine in Columbus. These compounds, which include tumor necrosis factor alpha and interleukin-6, are "all-purpose 'nasties' for aging," and have been tied to heart disease, type 2 diabetes, arthritis and other ailments, Kiecolt-Glaser told Reuters Health. Omega-3 fatty acids are found in foods such as fish, flax seed oil and walnuts, while omega-6 fatty acids are found in refined vegetable oils used to make everything from margarine to baked goods and snack foods. The amount of omega-6 fatty acids in the Western diet increased sharply once refined vegetable oils became part of the average diet in the early 20th century. ....Continued on http://news.yahoo.com/s/nm/20070417/hl_nm/fatty_acid_dc_1;_ylt=Atdx_ht5KwGEvnUyZUEX05i4wREB
