Purple Tomatoes May Help Prevent Cancer. (Web MD)

A new breed of tomatoes that are specially engineered to have extra antioxidants may help prevent cancer, according to a new study.

Scientists in Europe transferred certain genes of snapdragons to tomatoes, creating a tomato with a dark purple color and loads of antioxidants. Researchers tested the tomatoes on cancer-prone mice; they found that a diet supplemented by purple tomato powder increased the life span of the mice compared to mice eating a standard diet or a diet supplemented with red tomato powder.
