May boost brain health

As you become older, your brain function tends to deteriorate. While the mild mental decline is common, major neurological conditions such as Alzheimer's disease also exist.

Many studies have found that those who consume more fish had a reduced risk of mental decline. People who consume fish on a weekly basis have more gray matter, the brain's major functional tissue, in the areas of the brain that control emotion and memory, according to studies. Seafood, in particular, is high in DHA, an omega-3 fatty acid. The brain can benefit from omega-3 fatty acids by eating one or two servings of fish such as salmon, bluefin tuna, sardines, or herring.
