Antioxidants are substances that fight oxidation, meaning they protect us against free radicals. Free radicals are aggressive substances that can seriously damage the cells or tissue in our body. The damage they cause is called oxidative stress and occurs when there are too many free radicals or when they are in unwanted places in our body. In the long term, antioxidants are said to help prevent diseases such as cancer and cardiovascular disease and slow the ageing process.
Antioxidants are present in fruits and vegetables. The name antioxidants is actually a collection of all kinds of vitamins, minerals and other nutrients such as vitamin A, vitamin C, vitamin E, selenium, zinc and Q10.
