Dietary Hygiene Zhang Zhongjing, a physician in the Han Dynasty, talked about the taboos of animals, fish, insects and fruits and vegetables in his book synopsis of the golden chamber. It mainly means that dead animals can't eat, and rotten things can't eat. In fact, people are required to pay attention to food hygiene.

Confucius (55 BC1-479 BC) has long put forward that "color is evil, taste is evil, and food is defeated" and "fish is hungry and meat is defeated".

Jia Ming, a 100-year-old health expert in the early Ming Dynasty, specializes in dietary taboos and is the author of "Dietary Instructions". Zhu Yuanzhang (1328— 1398), the great emperor of the Ming Dynasty, summoned him and asked him what health preserving techniques he had. He said there was no such thing as a dietary taboo. So he dedicated the "food order" to the founding emperor. Jiaming lived 106 years old.

Dietary taboos also include quitting smoking and drinking.

Smoke was probably introduced into China in the early Ming Dynasty. At first, people thought that tobacco could cure diseases. Mao Lan (1397- 1446), a pharmacologist at that time, pointed out in Herbal Medicine of Southern Yunnan that tobacco is pungent and poisonous.

Doctors in Qing Dynasty found that smoking could cause acute poisoning and "spit yellow water and die", and they had a deep understanding of the harm of smoking. For example, during the Qianlong period of the Qing Dynasty (1736- 1795), Wu pointed out: "Smoking burns lung yin the most, causing people sore throat and many symptoms of cough aphonia, which may not be caused by smoking. It takes several years to consume blood, and health workers should stay away. "

Zhao Xuemin, a medical scientist, made a comparative observation on the harm of smoking: his friend Zhang Shou Zhuang coughed and expectorated because of smoking, "the medicine failed to cure, and it failed to heal year after year"; However, quitting smoking for a month will not only help you recover from coughing and expectoration, but also make you "mentally healthy and eat more". So he came to the conclusion that smoking consumes lung, blood, god and life, and should be quit.

There was a special book named "Quit Smoking" in Qing Dynasty, which suggested using 4 Liang (200g) raw tofu and 2 Liang (100g) brown sugar to steam tofu. When you want to smoke, you should eat some sugar tofu juice. It is said that I quit this method and don't want to smoke after 3 days.

Wine has a long history in China, and people used it to treat diseases in ancient times. Later, some people developed the bad habit of drinking, and alcohol became an important factor causing diseases. For example, Lu's Spring and Autumn Annals said: "Heavy drinking is the first disease."

But a small amount of drinking is good for the human body. Hu Sihui, an imperial physician in the Yuan Dynasty, analyzed the advantages and disadvantages of wine in his book Eating Right: "Wine, ... is the main medicine, which can dredge blood vessels, thicken the stomach, eliminate sorrow and drink less." Drinking more is harmful to life and easy to be human. "

Later generations of doctors agreed that drinking less alcohol is beneficial, which can promote blood circulation and exercise bones and muscles; Drinking more is harmful. Therefore, most old Chinese medicine practitioners like to drink a little wine, but few are addicted to alcohol.

Medicinal liquor is made of drugs for prolonging life and good mountain springs, which has the effect of prolonging life. For example, there is a man in Funiu Mountain who often drinks five-eye spring water and fine wine brewed by drugs. The old man lived to 104, and the eldest son lived to 123.
