What are the benefits of eating ice cream in winter?

People like to eat cold drinks, such as popsicles, ice cream, iced soda and so on. It's a hot day, but you should also pay attention to hygiene when eating cold drinks, otherwise it will be harmful to your health. Do not eat or eat less cold drinks in the following situations (1). Eat cold drinks in moderation and don't overeat. Because a large number of low-temperature cold drinks will cause gastric mucosal vasoconstriction, reduce gastric juice secretion, leading to loss of appetite or indigestion. At the same time, a large number of cold drinks will dilute gastric juice and reduce the bactericidal ability of gastric acid. Some intestinal pathogens easily enter the intestine through the stomach, causing dysentery, typhoid fever, enteritis and other diseases. In particular, children's gastric mucosa is tender, and eating too many cold drinks will damage the gastric mucosa, which is more likely to cause gastrointestinal diseases. (2) The elderly or the infirm should try to eat less or not to eat cold drinks. Because of their poor gastrointestinal function, eating cold drinks is easy to get gastrointestinal diseases. If middle-aged and elderly people with coronary heart disease eat more cold drinks, when low-temperature food enters the stomach through esophagus, it can cause contraction and ischemia of coronary arteries in the anterior and inferior walls of the heart, and induce angina pectoris or arrhythmia. (3) It is not advisable to eat a lot of cold drinks after strenuous physical labor or strenuous exercise. At this time, the whole body blood circulation is accelerated, and the blood in the gastrointestinal tract is relatively small. If you eat a lot of cold drinks, the gastric mucosal blood vessels will contract, which is prone to gastrointestinal dysfunction. It's best to drink some salty drinks first, and then have a rest before eating cold drinks. (4) Don't eat cold drinks before and after eating, otherwise it will affect the secretion of digestive juice and enzymes, reduce gastrointestinal function, and induce nausea, vomiting, abdominal pain, diarrhea or indigestion.

The main ingredient of cold drinks is water. Besides, ice cream and ice cream contain some sugar and milk. These nutrients are low in content and cannot be used as staple food to provide nutrition. If a large number of cold drinks enter the digestive tract, supercooling will seriously affect the secretion of digestive juice and gastrointestinal function. Normal digestive juice contains gastric acid and digestive enzymes, which helps to kill bacteria entering the digestive tract and promote food digestion and absorption. If the digestive juice is reduced, the digestion and absorption of food will be affected, which will easily lead to intestinal infection, loss of appetite, abdominal pain, diarrhea and fever.

timely

It is not advisable to eat cold drinks before or after meals.

Eating cold drinks before meals will affect appetite and lead to nutritional deficiency. Cold drinks contain nutrients such as milk, but the content is far less than normal diet. Eating cold drinks immediately after meals will reduce gastric acid secretion, reduce the immune function of digestive system, lead to bacterial reproduction, and cause intestinal diseases such as enteritis.

Proper amount

A large number of cold drinks enter the body, which can cause vasoconstriction of gastric mucosa and decrease the secretion of gastric juice, resulting in decreased appetite and affecting the digestion of food. The intake of a cold drink should be around 150ml.

speed

It's very hot in summer, so it's a good enjoyment to drink a can of frozen coke and bite off some popsicles in one breath. However, the damage to the body can not be made up by this refreshing. Drinking cold drinks is the same as drinking hot soup, savoring it carefully and drinking it slowly.

avoid

Different people have different requirements for cold drinks, especially those with diseases, so they should eat less or even avoid cold drinks. Babies avoid cold drinks, and children eat less cold drinks; People who are old and weak and suffer from cardiovascular diseases should not eat more cold drinks.

Be careful to eat cold drinks from roadside stalls. When buying, carefully check the production date and shelf life, and try to choose products with close factory date.
