We say "tomato" … and so does your heart. In what could be considered juicy news, a Tufts University study found that people who ate a tomato-rich diet had a significantly lower risk of coronary heart disease. The health boost comes from lycopene, an antioxidant that gives tomatoes their color and (pizza lovers, rejoice!) becomes even more concentrated in sauce. In the 11-year study, those who ate the most lycopene — watermelon is another rich source — had a 25% lower risk.
