Garbage in, garbage out. That's how the saying goes, anyway. And while it is quite easy to find examples of how our bodies reach peak performance when properly hydrated and fed, the dietary benefits for the mind are sometimes less obvious.

However, that is certainly not to say that what we eat has no impact on our brain function. In fact, a growing body of evidence suggests just the opposite; proper diet is crucial for maintaining a healthy mind.

MedicineNet.com offers these brain-healthy nutritional suggestions:

• Omega-3 fatty acids - They are found in fatty fish such as mackerel, herring, sardines, anchovies, whitefish, tuna and sablefish.
• B vitamin - Take one daily.
• Multivitamin - Also take one daily, but never exceed recommended dose. Taking more vitamins doesn't make it healthier - doing so could be dangerous.
• Vegetables - Eat as many as you can, of all different colors, shapes and varieties.
• Antioxidants - Found in vitamins C, E and beta carotene, you should get plenty of these substances. They occur naturally in many fruits and vegetables.
