The ADA recommends five or more servings of fruits and vegetables a day as part of a healthy diet. These plant foods can do many things to boost good health, including:
* Reduce the risk of some cancers
* Beat the signs of aging
* Improve memory
* Promote heart health
* Enhance the immune system
One way to incorporate fruits and veggies into your diet is to have them as snacks. "If you can do one thing [to improve your health], concentrate on getting fruits and veggies," says Johnson. "They are low in calories and high in nutrients."
She says baby carrots and cut-up produce make tasty, convenient munchies. Other healthful snacks include low-fat yogurt and nuts (in moderation).
The best time to snack is when you are hungry between meals, says Johnson. But beware: Cravings could easily be mistaken for hunger cues, especially for people who are dieting.
