Fruits and veggies are promoted to lower the risk of certain types of cancers. No one will tell us which ones and what nutrients or natural substances are associated with certain types of cancer. Thank You Lydia
The exact relationship between fruits and vegetables and cancer risk is not entirely clear, and is likely related to several factors. The scientific literature suggests that the benefit may be a result of foods and substances in foods working together as opposed to specific substances having a single effect. The scientific literature has pretty consistently shown that dietary patterns that include fruits and vegetables are associated with lower risk of some cancers as well as other chronic diseases such as cardiovascular disease and diabetes. These dietary patterns also tend to be lower in fat and animal fat, and higher in fiber. So, the effect may be a combination of factors. Some recent studies also associated diversity, or variety of intake of fruits and vegetables with lower risk for oral cancers, indicating that no one substance is the magic bullet. A recent report on Diet and Cancer was published by the American Institute of Cancer Research, which you can view at www.aicr.org. You can see what nutrients are in fruits and vegetables in our Fruit and Veggie Database. You can also view our Phytochemical Information Center at http://www.pbhfoundation.org/pulse/research/pic/ to see what other substances are in fruits and vegetables. Your best bet is to eat recommended amounts and include a variety of colorful fruits and vegetables every day. See “How Many Cups Do You Need?”.
