The effects of smog on the lungs are graphically illustrated in a study out of The Netherlands. Bicyclists were subjected to toxic ozone, then lung function was assessed. Forced expiratory volume decreased 95 ml without supplementation. With supplementation of 500 mg of vitamin C and 100 mg of vitamin E, the decrease was only 1 ml. Forced vital capacity decreased 125 ml without extra C and E, and only 42 ml with supplementation.
Lungs are especially dependent on vitamin C for protection.
In a study out of England, ascorbate was the only antioxidant that was significantly reduced in the lungs by ozone. An extremely powerful antioxidant, lipoic acid has demonstrated powers against brain damage, aging and diabetes. It may also help kill cancerous cells and retard heart disease. A remarkable study shows how lipoic acid can reverse aging. The aged rats were three times less active than young ones.
