Chinese food therapy uses food to adjust human body based on theories of traditional Chinese medicine in order to keep the body health or even cure disease. In Chinese food therapy, it is believed that food is the most natural source for providing nutrition and health is a result of the balance between different nutrition. Let’s put it this way: food is the best medicine. In Chinese food therapy, it is believed that food can treat disease, recover functions of cells and make human body healthy instead of medication. Balanced nutrition can improve the metabolism so that cells can be stronger. In addition, nutrition can also activate the immune system by increasing the number of immune cells in order to kill germs and virus. Strong immune cells can clean up dead cells and residue from metabolism. Thus the function of the cells can be improved so that the disease can be treated.
