Add more fruits and vegetables to your diet, especially tomatoes and members of the broccoli family. Drink more tea; cut back on meat and dairy.

Red alert: Eating lots of veggies, especially tomato-based foods, can lower a man's prostate risk.

Eat more of these:

• Tomato-based products. Soups, pasta sauces, and tomato-based juices increase your body’s stores of lycopene, a carotenoid found mainly in tomatoes. This phytochemical helps limit damage to cells like those in the prostate, and at least three studies have found that tomato intake and lycopene levels are linked to a reduced incidence of prostate cancer. You can also find lycopene in watermelon.

• Beverages containing polyphenols. Green tea and pomegranate juice are rich in antioxidant-containing polyphenols, which help prevent cell oxidation (chemical damage), and stop the spread of cancerous cells.

• Cruciferous vegetables. Broccoli, brussels sprouts, cauliflower, and bok choy all contain compounds that have been shown to protect cells from DNA damage. Several studies have shown that a high intake of these types of veggies is associated with a decreased risk of prostate cancer.
