As well as being good for the heart, tomatoes decrease risk of arterial aging, heart disease, stroke, memory loss, impotence, and wrinkling of the skin, Dr. Roizen says. And tomato-based products contain lycopene, which has been shown to fight cancer.
But to really reap the benefits, you can't just put a few slices of an heirloom tomato in your salad. The best way to get the positive effects is by eating 10 tablespoons of tomato sauce a week. "It takes 165 raw tomatoes to equal 10 tablespoons of tomato sauce," Dr. Roizen says. "So it's much easier to have tomato sauce."
Dr. Roizen adds that it doesn't matter what kind of tomato sauce you have, "as long as it's cooked, and you eat it with a little olive oil and a little healthy fat because it's much better absorbed with it."
