An article in the January issue of Mayo Clinic Women's HealthSource offers some clues. Here are a few of the experts' picks for favorite foods and why they recommend them:

· Broccoli: The experts say broccoli contains a phytochemical that may prevent growth of cancer tumors and lutein, a powerful vision-protecting antioxidant. They recommend including broccoli in your menu two to three times a week.

· Vegetables: Because they're high in nutrients and low in calories, vegetables can be a great choice if you're looking for volume. Consider this: One cup of vegetables is about 50 calories, while a cup of M&Ms is about 850 calories. The experts recommend eating vegetables every day.

· Apples: How can an apple a day keep the doctor away? Here's how, say the experts: Since they're a good source of phenol antioxidants, they can keep the "bad" LDL cholesterol from getting oxidized, and oxidized LDL is bad for your arteries.

· Soy nuts: They are a good source for protein and isoflavones, which may protect the heart and bones and reduce the risk of cancer.

· Fish: Salmon and tuna, in particular, are high in omega-3 fatty acids. They taste great and can be prepared many ways. Eat a 3-ounce portion once a week.

· Nuts: They are high in monounsaturated fat and are a great snack. Pistachios, in particular, are recommended for snacking and toasted almonds for salads.
