Eating plenty of fruits and vegetables every day is essential for good nutrition and good health. Many of the nutrients and phyto-nutrients found in fruits and vegetables are powerful antioxidants. Our body constantly produces free radicals as a natural by-product of our metabolism. There are also many external sources of oxidants or free radicals such as smoking, UV light and pollutions. Some free radicals are needed by our bodies but too many can damage cells by causing harmful chain reactions. This damage is often called “oxidative stress”. Antioxidants can help reduce the harmful reactions caused by free radicals.
Although the body produces its own antioxidants, the antioxidants we obtain from our diet, particularly those from fruits and vegetables, contribute significantly to reducing oxidative stress in the body. Scientific studies have confirmed that by simply eating more fruits and vegetables people may be able to reduce oxidative damage and help maintain a healthy immune system.
