China’s ancient medical doctors on the relationship between dietary imprudence and disease recurrence has a lot of discussion, and put forward the concept of “food recovery” (“food recovery” refers to the disease is healed, due to dietary imprudence and cause disease recurrence or change other diseases). Zhang Jingyue in the “Jingyue encyclopedia” in the cloud: “can not be strong food, strong food is to help the evil …… longitudinal food is food back,” pointing out that dietary regimen to take care of the spleen and stomach qi, if the disease is a longitudinal food, strong food, it will be loss of stomach qi, help to promote the growth of the evil qi, the old disease will be drinking too much food and back to the buds. Zhang Zhongjing believes that in the early stage of disease healing, because the evil is not exhausted, the spleen and stomach qi is not back, food therapy should be appropriate for people with disease selection. The Treatise on Typhoid Fever records: “When the disease is new, people are strong to give grain, the spleen and stomach gas is still weak, can not eliminate the grain, so it will make the slight annoyance, the loss of grain is healed”. It tells people that when the disease begins to heal, the spleen and stomach are often weakened and injured due to the torture of disease and evil, at this time, the spleen and stomach can not digest the food if they blindly take tonic and forced to eat, and the condition will be recovered if they appropriately restrict the food. It is not uncommon for tumor patients to suffer from recurrence and metastasis due to careless diet during the recovery period, so they have to be careful! Pang Anchang, a famous doctor, pointed out the method of post-disease tonic and said, “After recovering from a disease, it is appropriate to start with clear porridge soup, and then into the rice porridge, which must be less and less, and it is not necessary to eat too much. As for wine and meat, especially should be prohibited”. In the recovery period of the disease and rehabilitation period, just after the disease, the diet should be thin rice gradually thick, the number of less to more, so gradually, can not over-eat, as for wine and meat and other food, when it is forbidden and so on.
