It’s about how oxidative stress brought on by free radicals results in aging and the development of a variety of diseases such as cardiovascular disease, autoimmune disorders and some cancers.

A free radical is an atom with an unpaired electron. The nucleus of an atom is surrounded by a ring of paired electrons. Sometimes an atom loses an electron (referred to as oxidation), leaving the atom with an unpaired electron. The atom is then a free radical and is said to be highly reactive; it sets off a chain reaction of damaging events in the search for an electron to fill its outer ring. Free radicals damage DNA, proteins, cell membranes and other structures.

any free radicals creates a condition called "oxidative stress." Andrew Weil, in Healthy Aging, says that "oxidative stress is simply the total burden placed on organisms by the constant production of free radicals in the normal course of metabolism..."

Free radicals are produced in the body in a number of ways but the most common production occurs in the mitochondria (oxygen furnaces) through the electron transport chain. This is significant because this energy system is used to produce ATP (the energy currency of the cell) during aerobic metabolism. So when you spend endless hours doing aerobic exercise, you increase free radical production, oxidative stress and the likelihood of aging more quickly over time.

To reduce oxidative stress, cut back on aerobic exercise and do more anaerobic exercise, such as interval training. And, include an abundance of plant foods, which are loaded with antioxidants, in your diet. Our bodies have enzymes (antioxidants) th
