Antioxidants are powerful free radical scavengers. Free radicals are highly reactive chemical substances that travel around in the body and cause damage to cells.
Health experts believe free radical damage is one of the most prominent causes of aging and devastating diseases, such as cardiovascular disease and cancer that are responsible for killing many people in the Western world.
Many of the foods high in antioxidants are fruits and vegetables. The deeper and richer the color of the fruit or vegetable, the more phytonutrients that are present in it. Phytonutrients are the best antioxidant foods that exist in nature. Phytonutrients are concentrated in the skins of vegetables and fruits, and are responsible for the color, scent, and flavor. Tomatoes, broccoli, cauliflower, peppers, onions...are all excellent choices.
Clinical trials are now revealing that phytonutrients can enhance the strength of the immune system and prevent disease.
So, the next time you're walking thru the produce aisle, don't get the white onions -- get the red ones. If you like grapes, skip the green ones, and purchase the red ones. Instead of green peppers, try yellow, orange, purple, or red. Blueberries and bilberries are two of the best antioxidant foods you can buy – and are very rich in phytonutrients.
