Strawberries can lower the risk of cancers of the gastrointestinal tract, says LSU AgCenter nutritionist Dr. Beth Reames.
"Strawberries are a nutritious, healthy treat, because they are rich in vitamin C," the LSU AgCenter nutritionist says, adding, "Such foods can lower cancer risk."

Scientists at the Institute of Food Research (IFR) in the UK have begun work to identify the compounds in strawberries responsible for inhibiting the growth of cancer cells. They are hoping to develop new varieties in which the anticarcinogenic compounds are enhanced.
