Oxidation is a natural and necessary process in which cells are broken down or converted to other forms. Although oxidation reactions are crucial for life, if accelerated, the process can be damaging, so plants, animals and people maintain complex multiple antioxidant systems including vitamins, minerals, enzymes and dietary antioxidants. Pollution, physical and mental stress, drugs, alcohol and other chemicals can increase oxidation and excess oxidation generates free radicals that are linked to age-related degenerative conditions including vision problems, heart disease, diabetes, osteoporosis and Alzheimer’s disease. Vitamin E is a primary, fat-soluble antioxidant that protects the cells. In food, it is found in nuts, seeds, avocado, eggs and leafy greens. It is wise to consume antioxidants from a wide variety of sources to support overall health.
