However, the damage caused by an overload of free radicals over time may become irreversible and lead to certain diseases including heart and liver disease and some cancers such as oral, oesophageal, stomach and bowel cancers. Oxidation can be accelerated by stress , cigarette smoking , alcohol , sunlight, pollution and other factors.

Antioxidants are found in certain foods and may prevent some of the damage caused by free radicals by neutralising them. These include the nutrient antioxidants, vitamins A, C and E, and the minerals copper, zinc and selenium.

Other dietary food compounds, such as the phytochemicals in plants, are believed to have greater antioxidant effects than vitamins or minerals.

These are called the non-nutrient antioxidants and include phytochemicals, such as lycopenes in tomatoes and anthocyanins found in cranberries. A diet high in antioxidants may reduce the risk of many diseases including heart disease and certain cancers. Antioxidants scavenge free radicals from the body cells and prevent or reduce the damage caused by oxidation.

The protective effect of antioxidants continues to be studied around the world. For instance, men who eat plenty of the antioxidant lycopene found in red fruits and vegetables such as tomatoes, apricots, pink grapefruit and watermelon may be less likely than other men to develop prostate cancer.
