Fish is rich in unsaturated fatty acids and other nutrients. Regular consumption is helpful to promote children's intellectual development and prevent cardiovascular diseases. However, hairtail, silver carp, chubby fish, eel, etc. are all warm foods, which are easy to get angry when eaten too much, which is what people often say, "fish makes a fire." Therefore, those with excessive internal heat and strong constitution due to yin deficiency should eat less warm fish, and it is best to choose stew, steaming or braising in soy sauce when cooking. Similarly, you can't eat too much meat. When people say "meat produces phlegm", they don't mean that eating too much meat is easy to cough and produce phlegm, but that eating too much meat will lead to abnormal metabolism of body fluids and produce phlegm. Meat contains a lot of fat. Excessive intake can easily lead to the increase of blood lipid and blood viscosity. Clinical examination often shows the increase of blood thickness, aggregation and coagulation, which is an objective manifestation of phlegm and blood stasis in traditional Chinese medicine and an external reflection of "meat produces phlegm".

Compared with fish and meat, since ancient times, people seem to be more dependent on radish and cabbage. Although the folk proverb "Radish goes to the street, the drugstore has no business" is almost exaggerated, radish does have an auxiliary treatment effect on many diseases. Traditional Chinese medicine believes that white radish has the functions of promoting digestion, resolving phlegm, and relaxing bowels, and is suitable for patients with indigestion, abdominal distension, pneumonia, bronchitis, cough, etc. Carrots have the functions of invigorating the spleen, resolving stagnation, moistening dryness and improving eyesight, and are suitable for patients with dyspepsia, night blindness, keratoxerosis, etc.

The medicinal value of Chinese cabbage has always been highly valued by doctors in past dynasties. Chinese medicine believes that Chinese cabbage has the functions of clearing away heat, relieving annoyance, dredging the stomach and promoting diuresis. Modern medical research shows that Chinese cabbage is rich in cellulose, which can stimulate gastrointestinal peristalsis and play a laxative role. In addition, the cellulose contained in Chinese cabbage can also promote the absorption of animal protein, which plays a certain role in maintaining the normal balance of blood sugar, so diabetic patients might as well eat more Chinese cabbage.

It is necessary to avoid being partial to big fish and big meat, fat and thick, and to be vegetarian, with a combination of meat and vegetables. In addition, pungent, sweet, sour, bitter and salty flavors are beneficial to human liver organs, qi, blood, bones and muscles, so they should not be partial.
