Aging can be described as a processĀ  that decreases the number of healthy cells in the body. Experts are unanimous that the attack by free radicals caused by oxidative stress is the primary cause of aging. The oxidation process can be equated with the rusting process on a metal. In this case the cells of the body are attacked. The causes of aging also include almost all the degenerative diseases like cancer, heart disease, diabetes and others.

Aging is accelerated by some environmental factors also. Pollution plays a major role. Deficiency of antioxidants and the oxidative stress also contribute to aging. Increasing use of pesticides and herbicides has led to a decrease in protein, minerals and amino acids found in fruit and vegetables. Some experts say that over eating also contributes to aging.
