Superfoods and Dietary Supplements
Antioxidants are found naturally in varying amounts, in vegetables, fruits, grain cereals, legumes, nuts etc. Antioxidant sources / superfoods include:
- Fruits: berries and peppers, cider, wine
- Vegetables: spinach, tea
- Fungi: mushrooms
- Whole grain cereals: hops, barley, millet and maize (including beer)
- Nuts: pecans, pistachios, and almonds
- Beans: cacao (including chocolate), coffee
- Olive leaf tea
Since the discovery of vitamins, it has been recognized that antioxidants from the diet are essential for healthful lives in humans and many other mammals. More recently, a large body of evidence has accumulated that suggests supplementation of the diet with various kinds of antioxidants can improve health and extend life. Many nutraceutical and health food companies now sell formulations of antioxidants as dietary supplement.
These supplements may include specific antioxidant chemicals, like resveratrol (from grape seeds), combinations of antioxidants, like the “ACES” products that contain beta carotene (provitamin A), vitamin C, vitamin E and Selenium, or specialty herbs that are known to contain antioxidants such as green tea and jiaogulan. However, to date, the FDA finds insufficient evidence to endorse health claims that have been made regarding antioxidant supplementation.
