Antioxidants

The following vitamins have shown positive antioxidants effects:

• Retinol, Vitamin A or beta-carotene. It has been discovered that beta-carotene protects dark green, yellow and orange vegetables and fruits from solar radiation damage and it is thought that it plays a similar role in human body. Carrots, squash, broccoli, sweet potatoes, tomatoes, kale, collards, cantaloupe, peaches and apricots are particularly rich sources of beta-carotene.

• Ascorbic acid (vitamin C) is a water-soluble compound that fulfills this role, among others, in living systems. Important sources include citrus fruits (like oranges, sweet lime etc.), green peppers, broccoli, green leafy vegetables, strawberries, raw cabbage and tomatoes.

• vitamin E (tocopherol) is fat soluble and similarly protects lipids. Sources include wheat germ, nuts, seeds, whole grains, green leafy vegetables, vegetable oil and fish-liver oil.

• selenium It is best to get selenium through foods, as large doses of the supplement form can be toxic. Good food sources include fish, shellfish, red meat, grains, eggs, chicken and garlic. Vegetables can also be a good source if grown in selenium-rich soils.

Several food additives (including ascorbic acid and tocopherol-derived compounds) are used as antioxidants to help guard against deterioration of food. (see: preservative)
