First of all, because besides exercise, health care mainly depends on diet, daily diet and nutrition intake, and the stomach is the first and second pass for the human body to ingest food and absorb nutrition.

After the human body ingests food, it enters the gastrointestinal tract through the mouth and esophagus, and the mouth and esophagus have no effect on the absorption of nutrition. Therefore, the stomach and intestines are the vanguard positions to absorb nutrition.

Secondly, relaxing bowels and regulating the stomach can make nutrition better absorbed.

Because health care is mainly accomplished by nutrient absorption, and regulating the stomach can make the stomach absorb nutrients better, and defecation also plays a very important role, otherwise the digestive ability and metabolic ability of the stomach will be greatly reduced.

Furthermore, only when the intestines and stomach are unobstructed can toxins in the body be eliminated, so as to achieve the purpose of health preservation.
