Foods High in Antioxidants
From LoveToKnow Vitamins
Bright carotenoid-rich fruits and vegetables top of the list of foods high in antioxidants. Antioxidants are found in foods in the form of vitamins, minerals, carotenoids, and polyphenols and can often be identified in food by their distinctive colors, for example: the deep red of cherries.
Measuring Antioxidant Content
USDA Scientists developed a scale that rates and measures the antioxidant content of various natural plant foods. This scale is called ORAC (Oxygen Radical Absorbance Capacity). This database holds data for 277 food items. The information contained in this report is a collaboration between:
- Arkansas Children's Nutrition Center in Little Rock, Arkansas
- Beltsville Human Nutrition Research Center
- Nutrient Data Laboratory
How Antioxidants Prevent Cell Damage
First, to understand how antioxidants help prevent cell damage, let's take a look at free radicals. Free radicals are highly-reactive molecules that have the ability to start an unwanted chain reaction in cells. This chain reaction leads to damage. (UV light can produce free radicals.) Antioxidants offer a defense against cell damage. They react with free radicals and truncate the chain reaction before it damages molecules. Antioxidants include:
- Beta-carotene
- Selenium (found in fish and shellfish, red meat, grains, eggs, chicken and garlic)
- Vitamin C
- Vitamin E
Benefits of Antioxidants
If you're looking for a way to stay young, antioxidants can help. They protect cells from the main cause of aging--oxidative free-radical damage. However, the benefits reach much further than this. The anti-aging antioxidants found in carotenoids offer all kinds of other benefits, too. They've been proved to slow down, prevent and even reverse conditions like:
- Cancer
- Degenerative eye diseases such ascataracts and macular degeneration
- Diabetes
- Diseases of the immune system
- Diseases of the nervous system
- Heart disease
Choosing Foods High in Antioxidants
