Diet has been estimated to contribute to at least a third of all cancer-related deaths. Still, there is no definitive diet that will prevent cancer. Instead, experts propose a healthy lifestyle that includes physical activity, not smoking, and eating well, specifically: Eating a variety of whole-grain products (breads, cereals, pasta, rice), vegetables, beans, lentils and fruits. These foods contain fiber, which is believed to reduce the risk of cancers of the rectum and colon, and they're rich in anti-oxidants, minrals and other phytochemicals that play a role in cancer reduction.

• Eat foods low in total fat, saturated fat and cholesterol.

• Use sugar in moderation. Likewise, don't go heavy on salt; instead, use herbs and spices to flavor food.

• If you drink alcoholic beverages, do so in moderation and with meals.

Uterine-cancer mortality runs eight times higher among heavy women. Overweight women develop more cancers of the breast, ovaries and gallbladder. Overweight men have more cancers of the colon and rectum. That's proof enough that it pays to reduce health risks through better eating and exercise.
