You may have heard a lot of people talk about antioxidants. They do a lot of important jobs like keeping you healthy, by preventing the effects of ageing. But most of us dont really understand what they are and how they really work.

So what are Antioxidants?  How do they work? How to get them?

Antioxidants are naturally occurring substances although poor diet, pollution, smoking & drinking means that a lot of people don’t have enough of them. An antioxidant is a molecule that stops the oxidation of other molecules (which is a good thing).Antioxidant compounds found in natural foods that neutralize or ‘mop up’ molecules called free radicals that can harm our cells. Damage caused to cells by free radicals is linked to certain diseases such as cancer and cardiovascular disease. The best sources of antioxidants are fruits, vegetables, nuts and wholegrains.

So why are free radicals so harmful?

Some conditions caused by free radicals include:

  1. It can cause damage to the eye lens, which contributes to blindness
  2. Inflammation of the joints leading to arthritis
  3. It can damage the nerve cells in the brain, which can cause Parkinson’s or Alzheimer’s disease
  4. It accelerates the ageing process
  5. it increases the risk of coronary heart disease
  6. Even certain cancers, triggered by damaged cell DNA.

So a diet rich in antioxidants may reduce the risk of many diseases, including heart disease and certain cancers. Antioxidants eat up the free radicals from the body cells, and prevent or reduce the damage caused by oxidation. Thus to prevent our body from the damages done by the free radicals, we need to take these antioxidants regularly.

The following is a list of different kinds of antioxidants and foods that are high in each.

  • Allium sulphur compounds: Leeks, onions, garlic
