Eating fish has been tied with lower rates of heart disease, stroke, depression, and Alzheimer's disease. But how it you eat may be the real key to reaping its benefits.

Recent research from University of Pittsburgh School of Medicine concluded that study volunteers who regularly ate fish had larger brain volumes in regions associated with memory and cognition, but only if the fish baked or broiled, not fried.

Baking and broiling are also better for your waistline.

For example, a dozen fried shrimp can pack 280 calories, versus a mere 85 calories for 12 shrimp that have been steamed or broiled.

To make up the difference you d have to spend about 25 minutes on the elliptical.
