The earliest ice cold drink was ice food.
The earliest ice-cold drinks originated in China. Ice-cold drinks were called "ice food" in ancient times. China has a long history of drinking ice-cold drinks. Ice-cold drinks originated in the Shang Dynasty about 3,000 years ago. .
The "Book of Rites of Zhou" describes the ancient people's deeds of making ice cold drinks, "Lingren palmed ice to offer sacrifices to guests." At that time, wealthy people would cut ice and store it in their cellars in the winter. When summer came the next year, they would take the ice out of the cellars to make ice-cold drinks. The Zhou Dynasty also had "Ling Ren" who was in charge of "ice power". By the end of spring and autumn, ice was used for a wider range of purposes. The iced cold drink that princes like to drink at banquets is iced rice wine.
Precautions when eating cold food
1. It is not advisable to drink too much. Excessive cold drinks can cause gastric bloating and discomfort in mild cases, and can cause indigestion, gastroenteritis, diarrhea, etc. in severe cases.
2. It is not suitable to have too many types. The types of cold drinks consumed are too diverse, and the drinks are overlapping with each other, which is harmful to the body. Children should pay special attention to moderation when eating cold drinks in summer.
3. It is not advisable to drink too much after sweating profusely. Drinking too much after sweating will stimulate the contraction of blood vessels and skin, causing "closed sweating". Not only can it not quickly replenish and regulate water and salts in the body, but it will dilute gastric juice, leading to gastrointestinal diseases.
