As our ancestors said, Care of the body depends upon diet. Being drunk yet longing to drink more, being full yet craving to eat more are major impediments on the path to yang sheng or lengthening life. It is important for the elderly to have a well regulated diet. Overeating and overdrinking are harmful. In maintaining a better balanced diet and hence a healthy body, it is wise to eat more vegetables and bean products such as tofu.
Vegetables stimulate the secretive functions of various glands within the body.
Vegetables are easily digested and assimilated by the body. They can increase intestinal peristalsis and improve bowel movements. They can detoxify. They also prevent obesity, diabetes, heart disease, and other disorders. As one ages, the functioning of the zang and fu becomes debilitated.
