...model. "However, our data fit in with the general picture that lycopene and vitamin E may have chemopreventative effects on prostate cancer. Therefore we would certainly recommend that all men regularly eat lycopene and vitamin E-rich foods: for example, all kinds of processed tomato products, papayas, pink...UT Southwestern biochemist honored with NIH Director's Pioneer Award
