The antioxidant substances found in antioxidant fruits may work to neutralize these free radicals and in the process prevent them from causing damage. Antioxidant Fruits: The Benefits Many people are already familiar with antioxidant fruits, such as citrus fruits which are known for their high vitamin C content or apples for their beta-carotene. Groups of well-known natural antioxidants include catechins, coumarins, indoles, and carotenoids. All these are complex compounds found in almost every plant. Carotenoids are the largest group of naturally occurring antioxidants, followed closely by indoles and coumarins. Catechins are the natural antioxidants found in the Camellia sinensis plant where we get our green tea, oolong tea, and black tea. But what if there is a way for us to retard the development of free radicals? What if there is a way to break the free radical chain reaction? What if there is a way to prevent those diseases caused by harmful free radicals from developing? Yes, indeed, there is a way. Antioxidant foods are powerful substances that can neutralize free radicals before they damage your body's cells. Antioxidant enzymes may also stop the free radical from forming in the first place. In addition, they may also interrupt an oxidizing chain reaction to minimize the damage caused by free radicals. In sum, the main function of antioxidant enzymes is neutralizing free radicals. For the past decade, countless studies have been devoted to the beneficial effects of antioxidant enzymes. The small red bean was dubbed the food with the highest concentration of disease-fighting antioxidant compounds per serving. Antioxidants are the heroes in an epic struggle against villain molecules called "free radicals." Free radicals do nothing but assault cells, turning them into molecules like themselves. Herbal antioxidants are of course found in fresh produce, fruits, and vegetables. A large number of members of the berry family are excellent sources of herbal antioxidants. In fact, most herbal antioxidants you find sold in health food stores today are comprised mainly of berry extracts. Studies have shown that berries are rich in certain herbal antioxidants that help reduce atherosclerosis by acting on the agents that causes the clogging and the hardening of the arteries.
