Study shows that men who ate more pizza had less prostate cancer. The protective factor in pizza may be a pigment in tomatoes called lycopene, which blocks the free radicals, strengthens the immune system, and may help regulate cancer genes.
Cofounder of Helios Health Center in Boulder, Colorado, prescribes a teaspoon a day of tomato paste for his patients with prostate cancer. Lycopene has more potent antioxidant properties than beta-carotene, and it has anti-cancer properties too.
