Antioxidants are compounds in foods that search for and neutralise free radicals produced by the ever present process of oxidation in the human body. Therefore, antioxidants are vital to prevent some of the damage caused by free radicals. Oxidation, a natural chemical process happening all the time in the body, occurs on the cellular level when an atom loses electron(s) during chemical interactions with other atoms, and as a result may become a free radical (i.e. an unstable chemical molecule).
Free radicals damage cell membranes (especially phospholipids), LDL cholesterol and many other body structures including DNA. The body can cope with some free radicals and even needs them to function effectively. However, the damage caused by an overload of free radicals over time may become irreversible and lead to certain illnesses including heart disease, liver damage and some cancers.
Free radicals production can be accelerated by stress, poor diet, cigarette smoking, alcohol, environmental pollution and other factors. Some of the degenerative conditions caused by free radicals include:
- Increased risk of coronary heart disease, since free radicals encourage LDL cholesterol to stick to artery walls
- Inflammation of the joints associated with arthritis
- Damage to nerve cells in the brain which contributes to conditions such as Parkinson’s or Alzheimer’s disease
- Acceleration of the ageing process
- Certain cancers triggered by damaged cell DNA
- Deterioration of the eye (cataracts)
Needless to say, antioxidants are absolutely essential for the body to be healthy and perform well. Many antioxidants are vital for the immune system function and the reduction of oxidative stress as an inflammatory trigger. One of the most important applications of antioxidants is their anti-ageing properties.

There is increasing evidence that antioxidants are more effective when obtained from whole, organically grown foods, rather than isolated from a food and presented in tablet form. The best way to get a great variety of antioxidants in the diet is to eat deeply coloured plant foods every day as each colour indicates unique antioxidant properties. Purple and black coloured foods are especially valuable.
As a bonus, foods high in antioxidants are also high in fibre and are excellent sources of other vitamins, minerals and phytochemicals. However, in certain cases taking a high quality antioxidant supplements for a period of time is also highly beneficial as it will considerably speed up healing and regeneration.
