(HealthDayNews) -- An apple a day may keep the doctor away, but if you're concerned about cancer, eat grapefruit and tomatoes.
Researchers at Texas A&M University says these fruits have high levels of lycopene -- a nutrient that helps fight prostate, breast and cervical cancers. Lycopene is a powerful antioxidant that prevents the formation of "free radicals." (These steal oxygen from healthy cells, and may eventually trigger cancer.)
Tomatoes are the best source of lycopene, but red grapefruit is a close second. Grapefruit also contains other antioxidants, including vitamin C.
Here's a hint: the redder the flesh in a ruby grapefruit, the more lycopene it contains.
