Very good for you. UCLA researchers have discovered that fish oil may be the secret to preventing Alzheimer’s disease, a disease that affects over five million people in the United States alone. Scientists demonstrated that the omega-3 fatty acid DHA, found in fish oil, increases the production of LR11, a protein that is found at reduced levels in Alzheimer’s patients. UCLA researchers tested the effects of DHA by adding it directly to human and animal neurons grown in the laboratory.
Fatty acids such as DHA are considered essential fatty acids, because the body cannot make them from other sources and must obtain them through diet. Years of research have shown that DHA is the most abundant essential fatty acid in the brain
