Oxidative stress has documented relationships in the development of over 50 diseases, some of them life threatening. Included are inflammatory diseases, pancreatitis, heart disease, and cancer.  Oxidative stress also speeds the aging process.

While breathing less oxygen is obviously not an answer to the problem of cellular damage caused by free radicals, there are ways to fight back. The most important weapon against free radicals is a group of compounds collectively known as antioxidants. The compounds, found naturally in many foods and beverages, stabilize and deactivate free radicals before oxidative stress occurs.

The best way to get sufficient amounts of antioxidants is through a well-balanced diet which contains antioxidant rich foods such fresh fruits, vegetables, and many herbs. Green tea is also an excellent source.
