Better health for your teen could be as close as your breadbox. The more whole grains teenagers eat, the leaner they are and the less likely they are to develop diabetes.

Just what should kids be drinking? "I think good old H2O,'' says the director of the Nutrition Information Center in New York. But you can add pizzazz: Buy flavored water or make your own with lemon or lime.

If your teen wants vegetarian options, you may worry that dropping meat, poultry and fish will be unhealthy.

Encourage your teen to eat three balanced meals a day, with fruits or vegetables as snacks.
