If you want to be at your mental best, you'll want to pay attention to what and when you eat. Some experts now recommend the following:

  • FISH. Eating fish on a regular basis -- perhaps as little as once a week -- may reduce the risk of developing Alzheimer's disease. Fish can also promote better short-term memory.
  • BERRIES. Strawberries and blueberries, rich in antioxidants, are thought to protect the brain from aging-related cell damage.
  • WATER. Like all of the organs, the brain works best when the body is well-hydrated.
