Fish is a rich source of omega 3 fatty acids, which have been found to enhance the brain power. These healthy fats are linked to lower dementia and stroke risks and may help slow mental decline especially as we age. For optimal intake, the American Heart Association recommends eating at least two servings of fish weekly. Fatty fish like salmon, mackerel, herring, lake trout, sardines and albacore tuna are especially high in omega-3 fatty acids.
Extra benefit: Omega 3 fatty acids are also good for the heart and help lower the risk of cardiovascular disease.
