Is it bad for my health to eat cold drinks immediately after eating? Please explain the specific rea

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.

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.

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.

Timely. It is not advisable to 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.

Amount. A large amount of cold drinks entering 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.

Velocity. In the summer heat, it is a good pleasure to drink a frozen cola in one breath and bite off a few popsicles. 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.

Do-no. 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 are rich in flavor.

From the classification standard 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.

It can affect the absorption of nutrients by the digestive tract. Because people sweat a lot in summer, if they eat too much cold drinks, it will reduce the temperature of the gastrointestinal tract, affect the digestion and absorption of nutrients by the gastrointestinal tract, and in the long run, it will lead to indigestion and even gastrointestinal diseases. Eating too many cold drinks will affect the bactericidal power and digestion of gastric acid, which can easily lead to malnutrition and illness.

The development of the gastrointestinal tract is not perfect, and eating too many cold drinks is prone to poor digestion, nausea, vomiting, abdominal pain and diarrhea, etc., and in severe cases, it will also cause acute gastroenteritis. Excessive consumption of cold drinks will affect normal eating, thereby reducing the absorption and absorption of nutrients, and will cause osteoporosis for a long time. Therefore, there are a few things to pay attention to when eating cold drinks:

Don't eat cold drinks after strenuous exercise, as it can cause blood vessels in the stomach to constrict, so it's best to drink plain water or salty drinks first. Do not eat cold drinks before and after eating, it will affect digestion and lead to gastrointestinal problems. Eat cold drinks in moderation, not too much, otherwise it is easy to cause throat diseases.

It is not appropriate to eat cold drinks within half an hour after eating, at least it will have a bad effect on the digestive problems of gastric motility.

If you eat rotten ears to make hot food, eat cold drinks immediately, it is easy to cause stomach problems, and stomach diseases should avoid eating "raw cold and hard", eat regularly, regularly and quantitatively, can form a conditioned reflex, help the secretion of digestive glands, and be more conducive to digestion.

It should also be noted that the function of the stomach will be impaired after the stomach is cold, causing the digestive system to decline and cause indigestion.

Dyspepsia is a disease caused by gastric motility disorders, including gastroparesis and esophageal reflux disease, which include poor gastric peristalsis.

Symptoms: intermittent epigastric discomfort or pain, fullness, heartburn (acid reflux), belching, etc. They often do not want to eat or eat as little as possible due to discomfort such as chest tightness, early satiety, abdominal distention, etc., and it is not easy to sleep peacefully at night, and they often have nightmares after sleeping.

Therefore, the above conclusion is that it is not easy to eat cold drinks immediately after meals.
