Toddlers whose diets include orange juice and plenty of oranges and bananas are significantly less likely to get leukemia before age 14, according to a report in the American Journal of Epidemiology. Doctors at the University of California, Berkeley, surveyed moms of more than 300 children with leukemia and a comparable number of parents with kids who were cancer-free about their children’s diets before age 2. Birth weights and breastfeeding duration were similar among all the children. But those who ate oranges or bananas or drank orange juice four to six times a week were half as likely to develop leukemia, the most prevalent type of cancer among children. Further research is needed to determine whether vitamin C—perhaps when combined with other vitamins in fruits—is what’s protecting the body from cancer-causing substances.
