The Best Brain Foods

1. Fish

Fish has been considered a brain food for a long time, and recent research backs the claim. Many types of fish contain lots of omega-3 fatty acids and fish oils. Plain tuna from the can may be the easiest and cheapest way to include fish in your diet. Otherwise, wild-caught salmon are a great source.

Be aware, though, that many fish - both wild caught and farmed - now contain mercury, which is a brain toxin. So unless you are eating trout caught from high mountain streams with pure water, you should probably limit your fish intake to no more than three times weekly. That amount has been shown to be good for the brain.

Fish, by the way, is one of the brain foods that has both immediate and long-term benefits. It has been shown that brain waves actually speed up after a meal that includes fish. The fish oils also help keep arteries clean, preventing a major cause of brain problems: reduced blood flow to the brain.

2. Vegetables

Vegetables are a great source of beneficial vitamins, fiber and antioxidants. Vitamins nourish the brain cells. Antioxidants prevent or slow oxidative damage to our body, including the brain. When cells use oxygen, they produce "free radicals," harmful by-products which cause damage. As "free radical scavengers," antioxidants prevent and repair the damage done. Finally, fiber reduces the build-up of toxins in the body (and brain) by keeping the body cleaned out.
