According to a study published last week, daily servings of fruits and vegetables does not increase breast cancer survival rates. The current results contradict previous findings that diet made a big difference in reducing breast cancer risk.
Breast cancer survivors were assigned to 2 groups : a control group that followed the FDA nutrition guidelines and an intervention group that was instructed to consume 8 servings of fruits and vegetables, plus 16 ounces of fresh vegetable juice and permitted to eat meat but consume no more than 20% of total calories from fat.
Some cancer experts said that the study was poorly designed and executed: participants self-reported their eating habbits, most did not reach the target of fat reduction and the participants already ate more fruit and vegetables than most Americans before the study started. Some experts said the conclusions were misleading fearing it would discourage breast cancer survivors from pursuing a healthy diet.
The study "Influence of a Diet Very High in Vegetables, Fruit, and Fiber and Low in Fat on Prognosis Following Treatment for Breast Cancer" was published in JAMA. 2007;298:289-298. Read the abstract.
