COMMON ANTIOXIDANTS

The term ‘antioxidant’ is often used to describe different foods, but it more accurately describes a chemical property. Any substance that can strip free radicals of their damaging properties is considered an antioxidant. Researchers have discovered hundreds of substances that fit the antioxidant description, and there are bound to be thousands more.

Vitamin C and vitamin E are two of the most common antioxidants found in food. In addition to fighting free radicals, vitamin C supports the immune system and helps repair bones, teeth and cartilage. Vitamin E is a powerful tool in maintaining eye health, producing hormones that regulate blood pressure and repairing muscles after exercise.

Carotenoids – a class of compounds found in fruits and vegetables that are red, orange and yellow – are also well-known antioxidants. Antioxidant carotenoids include beta-carotene, lycopene, lutein and zeaxanthin. However, taking high doses of some carotenoid supplements, such as beta-carotene, can increase health risks, such as an increased chance of lung cancer in smokers. Other antioxidants include selenium, allicin, glutathione, flavonoids and curcumin – all found naturally in foods such as turmeric, apples and even wine.
