Dr. Roizen beams when he talks about one particular food: tomatoes. "They decrease cancer and they decrease arterial aging, heart disease, stroke, memory loss, impotence, wrinkling of the skin," he says. "In fact, Dr. Oz and I think a small town should be named after aspirin: it's that important. But a whole country should be named after tomatoes!"
So should they be raw or cooked? "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."
