AFTER CANCER: ANTIOXIDANTS. DIET
What about the Role of Fruits and Vegetables in Protecting against Future Cancer?
Epidemiologic studies have shown that people whose culture is characterized by a diet rich in fruits and vegetables have a lower risk for certain types of cancer than those whose diet is lacking in these foods. In addition, when people who normally eat few fruits and vegetables add fruits and vegetables to their diet, they appear to lower their risk of developing certain cancers. The relationship between eating fruits and vegetables and reducing risk is not an association; these foods actually do cause changes in the Ь that protect against cancer.
We do not know whether the benefit is due to the antioxidants in the fruits and vegetables or to some other substances, not present in synthetic supplemental antioxidant pills.
In the United States the National Institute of Health (NIH. conducting many studies in humans to look at the role dietary and
supplemental antioxidants play in protecting against future cancers. However, no well-controlled human studies have yet given a definitive answer to the question about the benefit of supplemental antioxidants.
What Should I Do about Antioxidants in My Diet until the Results of Current Studies Are Available?
The National Health and Medical Research Council recommends that adults eat at least 300g of fruit and 375g of vegetables a day. (This equates to approximately 2 pieces of fruit and 5 half-cup serves of vegetables a day.)
