Study: Eating fish might cut dementia risk

August 14, 2009 Researchers surveyed 15,000 older adults living in China, India or one of five Latin American countries. What they found is the odds of having dementia generally declined as fish consumption increased.

The research published in the American Journal of Clinical Nutrition mirrors similar results from previous studies. If fish does protect the aging brain, researchers believe that the benefits probably come from the omega-3 fatty acids found most abundantly in oily fish like salmon, mackerel and albacore tuna.
