Genesis Experts Discuss Food As A Prevention Tool

Think of them as nature's candy. Those colorful cornerstones of a nutritious diet - fruits and vegetables! Everyone knows that fruits and vegetables are full of the essential vitamins we need to maintain a healthy lifestyle. But what some of us may not know is that they also contain essential compounds that help protect and fight against cancer.

These compounds, called phytochemicals, are produced by plants and can be found in fruits, vegetables, beans, and grains. "There is some evidence that phytochemicals may help prevent the formation of potential cancer-causing substances (known as carcinogens), block the action of carcinogens on their target organs or tissue, or act on cells to suppress cancer development," explains Pat Christy, Manager of the Genesis Regional Cancer Center. Some scientists estimate that people can reduce their risk of cancer by 30 percent to 40 percent simply by eating more fruits, vegetables, and other plant sources that contain phytochemicals.

"We already know that eating at least five servings of produce a day - just that one lifestyle change - decreases cancer risk by as much as 20 percent," explains Polly Graham, Chief Clinical Dietician at Genesis Medical Center. "That's a pretty powerful incentive."

Flavonoids, a subgroup of phytochemicals, are plant chemicals found in a broad range of fruits, grains, and vegetables. The flavonoids found in soy products, garbanzo beans, chickpeas, and tea may mimic the actions of the female hormone estrogen. Flavonoids are being studied to determine whether they can prevent chronic diseases such as cancer.

The essential mineral, Selenium, is also thought to prevent the development and progression of cancer. Found in soil, selenium is converted to organic compound by plants and small living organisms. It is said to help preserve the elasticity in body tissues, slow the aging process, improve the flow of oxygen to the heart, and help prevent abnormal blood clotting. Selenium is claimed to protect the body against cancer by causing cancer cells to die before they have a chance to grow and spread. The best sources of selenium include whole grains, cereals, and Brazil nuts.

"Make healthy choices," Ms. Graham says, "the vitamins, the minerals, the fiber - the phytochemicals that are in most all fruits and vegetables. We're finding out more and more about this stuff all the time."

Genesis Regional Cancer Center is launching a community educational program to encourage a healthy diet and an active lifestyle. The Five-A-Day Program follows the American Cancer Society's guidelines of five daily servings of fruits and vegetables, which helps to reduce the risk of cancer and maintain a healthier lifestyle.
