A new study suggests that eating a diet that's rich in omega-3 fatty acids such as fish, soy, or nuts, may help starve off Alzheimer's. The study consisted of 1,219 people over the age of 60 who were free of dementia. Participants recorded their daily eating habits for a little over a year. Researchers paid more attention to the participants' intake of 10 different nutrients including, including saturated fatty acids, omega-3 and omega-6 polyunsaturated fatty acids, monounsaturated fatty acid, vitamin E, vitamin C, beta-carotene, vitamin B12, folate and vitamin D. Researchers also tested for levels of beta amyloid, a protein that helps identify if a person has Alzheimer's, in blood samples.They found that the more omega-3s a person consumed, the lower their blood levels of beta amyloid. Most of the omega-3s consumed by study participants came from fish, chicken, margarine, nuts and salad dressing. The study looked at nutrients that came only from food, not supplements.
