Concentrated cooked tomato products, such as ketchup and purée, contain remarkably effective amounts of lycopene, the antioxidant red pigment found in red fruit and vegetables. In a largescale European study, men with the highest intake of lycopene-rich foods were half as likely to suffer from a heart attack than those whose diets featured the lowest amount. Lycopene protects the heart and is good for blood pressure, suggests a recent study, and is also known to combat prostate cancer. The darker the fruit, the more lycopene it contains. Aim for a mighty 10 servings of fresh and cooked tomatoes a week, making sure they are organic: organic ketchup contains 83 percent more lycopene than nonorganic.
