Color Your Plate - The Benefits of Eating a Variety of Colors Everyday
Ever hear it is important to include as many colors of the rainbow in your diet as possible? The colors on your plate can provide a wide variety of vitamins, minerals and antioxidants.
What is an antioxidant?
Any substance that reduces oxidative damage (damage due to free oxygen in the body, which harms cells) such as that caused by free radicals is considered an antioxidant. Well-known antioxidants include a number of enzymes and other substances such as vitamin C, vitamin E and beta carotene (which is converted to vitamin A) that are capable of counteracting the damaging effects of oxidation. Antioxidants are also commonly added to food products like vegetable oils and prepared foods to prevent or delay their deterioration from the action of air. Antioxidants may possibly reduce the risks of cancer and age-related macular degeneration (damage to the eyes).
What is a free radical?
Free radicals are highly reactive chemicals either made by the body or taken in from the environment that harm the structure of enzymes and tissues in the body by binding to them. Both free radicals and antioxidants are created on a daily basis by your body. However, in today's environment, it is common to overwhelm the antioxidants and cause free radical damage. It is important to choose a wide variety of fruits and vegetables on a daily basis to ensure your body has what it needs to fight free radical damage.
