How much harm can it do to the body to eat cold drinks immediately after a meal

The main ingredient in cold drinks is water, in addition, ice cream, ice cream, etc. contain some sugar and milk. These nutrients are low in content and cannot be used as a staple food to provide nutrients. If a large amount of cold drinks enter the digestive tract, overcooling can seriously affect the secretion of digestive juices and gastrointestinal function.

Normal digestive juices contain stomach acid and digestive enzymes, which help to kill bacteria entering the digestive tract and promote the digestion and absorption of food. If the digestive juices are reduced, the digestion and absorption of food will be affected, and it is easy to cause intestinal infection, loss of appetite, abdominal pain, diarrhea and fever. Do not eat cold drinks before or after meals.

Eating cold drinks before meals can affect appetite and lead to nutrient deficiencies. Cold drinks contain nutrients such as milk, but they are nowhere near as high as a normal diet. Eating cold drinks immediately after meals reduces gastric acid secretion and reduces the immune function of the digestive system, leading to the reproduction of bacteria and causing intestinal diseases such as enteritis.

A large amount of cold drinks into the body can cause vasoconstriction of the gastric mucosa, reduce gastric juice secretion, lead to decreased appetite and affect the body's digestion of food. The intake of cold drinks should be about 150ml at a time. Speed In the summer heat, pouring a frozen cola in one breath and biting off a few popsicles is a good enjoyment to beat the heat.

However, the harm to the body cannot be compensated for with the freshness of this time. Drink cold drinks as well as hot soups, savor them carefully and drink them slowly. Different groups of people have different requirements for cold drinks, especially those with diseases, who should eat less or even avoid cold drinks.

Babies should avoid cold drinks, and young children should eat less cold drinks; People who are old and frail and suffer from cardiovascular diseases should not eat more cold drinks. Be cautious of cold drinks from roadside stalls. When purchasing, carefully check the production date and shelf life, and try to choose products with a closer factory date.

Carbonated drinks have rich flavors From the classification standards of soft drinks in China, there are really many flavors of carbonated drinks: fruit juice, fruit, cola, low-calorie and other types of carbonated drinks. Professor Zhang Jiazhi said that the juice-based carbonated drinks add original fruit juices, such as orange juice soda and orange juice soda, and the juice of fresh fruits is squeezed into the soda and added to the soda, which adds a lot of vitamins and other nutrients.

But compared with it, fruit-flavored carbonated drinks are prepared with flavors, such as orange soda, lemonade, etc., although the color is bright, but it only imitates the taste of fruit, not fresh fruit, so the nutritional value is much inferior.

On hot days, popsicles, ice cream, and ice cream have become people's favorites. Especially after a meal, a bite of sweet ice cream will not only remove all the greasy in your mouth, but also feel much more comfortable. However, although this is comfortable, it is painful to the stomach.

Studies have shown that after eating a large glass of ice cream quickly, the temperature in the stomach will drop rapidly from 37 degrees Celsius to below 20 degrees Celsius, causing the stomach to contract, reduce gastric acid secretion, and temporarily "strike" the peristalsis digestion work. It takes about 30 minutes or more for the stomach to warm up before digestion returns to normal. In this way, it is easy to cause food accumulation, bloating, and indigestion if you do it too often.

At the same time, a large number of cold food products will dilute gastric juice and reduce the bactericidal ability of gastric acid, and some intestinal pathogenic bacteria will easily enter the intestine through the stomach, causing people to suffer from dysentery, typhoid, enteritis and other diseases. Therefore, try to eat less raw and cold food after meals, and even if you do, you should wait at least 1 hour between them. In addition, it is not advisable to eat a lot of cold drinks after intense heat exercise.

At this time, the blood circulation of the whole body is accelerated, the blood in the gastrointestinal tract is relatively small, and eating a large amount of cold drinks will cause the blood vessels of the gastric mucosa to constrict, and it is easy to cause gastrointestinal dysfunction.

This situation is very bad for the body.

This is because most of the blood in the human body is concentrated in the stomach and other digestive organs after meals, and the gastrointestinal activity is relatively active.

Decreased, the activity of the stomach is weakened, it is difficult to digest food, and a state of fullness is formed, resulting in discomfort. From a biochemical point of view, the most active temperature of digestive enzymes is 37 38, and cold drinks will weaken the digestion of various digestive enzymes in the digestive juice after entering the gastrointestinal tract, which will cause gastritis, indigestion and malnutrition over time.

In particular, many people like to make a cup of strong tea to drink after eating, and some people eat some raw fruits and eat a cold drink after a meal to get rid of greasy, in fact, these practices are incorrect, especially bad for health. What should be avoided after eating? What can't you eat after a meal?

Let me share it with you.

Serve a cold drink immediately.

In particular, many young people like to eat cold drinks and cold drinks, and they want to eat ice cream just after eating. However, eating cold drinks after meals is particularly likely to lead to a variety of digestive disorders. Especially for older people, the stomach and intestines are particularly sensitive to cold and heat, and eating cold drinks with acorns after meals can cause stomach cramps, leading to abdominal pain, diarrhea and indigestion.

It is recommended to wait 1 hour after a meal before eating.

Drink strong tea after meals.

Drinking tea with tassels after meals will cause a lot of water to enter the stomach, which will weaken the digestive juices secreted by the stomach itself, and then affect the digestion of food by the stomach. Tea contains a lot of tannins, drink strong tea after meals, eat before digesting, protein and tannic acid combine to form a precipitate, protein can not be better absorbed; The substances in tea will also prevent the absorption of iron, and if you develop a problem with drinking strong tea after meals for a long time, it will cause iron deficiency anemia. It is recommended to eat with soup and water to help dissolve the nutrients in the food.

If you do not compensate for water before or during meals, excessive secretion of digestive juices after meals can cause body fluid loss and feel particularly thirsty, which will weaken gastric juice and affect digestion after drinking.

Avoid eating raw fruits after meals.

In particular, many people like to eat some raw fruits after meals, thinking that they can compensate for the carbohydrates and trace elements needed by the human body through this method, and can also relieve oiliness, which is not correct. After the food enters the stomach, it needs to be digested through 1 2 small mountains in the spring, and if you eat raw fruit immediately after eating, you will be hindered by the food you ate before, so it will not be particularly easy to digest.

After eating, you should take a break and be hungry, don't be busy exercising, can't eat cold drinks immediately, don't drink a lot of water, and don't sleep on a horse-shaped cover, these things should be paid attention to.

Don't go to bed immediately after you're full, don't sit down right away, don't drink too much water in the pretense of land, you can slip a little bit after you're full, eat betel nut immediately after you're full, and eat cold drinks immediately after eating.

I don't think you should lie down immediately after you've eaten, you shouldn't do stupid sailing, you shouldn't go out for a run immediately, and you shouldn't move the sedan car immediately. After eating, you can't take Kai to eat cold drinks immediately.

Why should I not drink a lot of cold drinks after strenuous exercise?
