The weather is getting hotter and hotter, and the joy of life for many people is probably a cup of ice water before and after a meal, but there are always people who remind "don't drink ice, it's not good for the stomach"
Many people feel that cold water is not suitable for drinking, and hot water can be regarded as a "good medicine", cold, fever, stomach pain... Both emphasize "drink more".
But have you ever thought that ice water really hurts your stomach? And the high incidence of gastrointestinal diseases in the mainland, what factors are related?
Does ice water really hurt your stomach?
Many people feel that as soon as they drink ice water, they will have diarrhea, abdominal pain and other problems, so they regard ice water as a "flood beast". In fact, the stomach upset can't just blame ice water.
Ice water, in fact, has little effect on the stomach
Cold things pass through the mouth, esophagus, and are not so cold when they reach the stomach, especially when they are slowly eaten in the mouth or eaten very little, generally do not reach the point of harming the stomach and intestines.
And people are thermostatic animals, the body has a set of strict temperature regulation mechanism, the temperature change in the stomach will be controlled within 0.3 ° C - when you drink ice water, the body will tremble, that is, the body temperature center sends signals to the body, through muscle tremors, generate more heat, to restore the normal temperature in the stomach.
As for why someone drinking ice water is uncomfortable, mainly due to:
● Sensitive to cold things
Different people have different reactions and tolerances to cold, and it is uncomfortable to drink ice water, probably because the smooth muscles of the digestive tract are relatively more sensitive to temperature, and the cold diet eaten makes the gastrointestinal tract spasm.
● The water is not clean
Drinking ice water may also be related to the unclean water, if there are some bacteria, parasites, etc. in the water, it may cause abdominal pain and diarrhea.
These 3 types of people are really not suitable for drinking ice water
Although there will not be much difference between cold water and hot water, these types of people should still pay more attention:
● People who have a bad gastrointestinal tract themselves
For example, people with irritable bowel syndrome, poor gastrointestinal digestive function, or gastrointestinal diseases.
Ice water can irritate blood vessels in the stomach, cause transient contractions, and intestinal spasms, resulting in stomach pain, diarrhea, etc.
● People with a history of migraine
When these people eat some cold food, they will irritate the oral mucosa, which will lead to the constriction of blood vessels in the head and face, affect the nerve center, and cause headaches.
Although it did not last long, it was very uncomfortable.
● After exercise
After exercise, the blood vessels in the gastrointestinal tract dilate and blood circulation accelerates.
At this time, drinking ice water will stimulate the blood vessels and mucous membranes of the gastrointestinal tract, causing the blood vessels and mucous membranes of the gastrointestinal tract to contract sharply, resulting in gastrointestinal spasms, resulting in abdominal pain, bloating, diarrhea and other symptoms.
Tips
Hot water is not the higher the temperature, the better, too hot water will damage the esophageal mucosa and the mucosa of the digestive tract, etc., increasing the possibility of esophageal cancer.
Therefore, daily drinking water and diet should be mild, not more than 65 ° C.
The incidence of gastrointestinal diseases in Chinese people is high
There are 6 main triggers
Helicobacter pylori infection
Helicobacter pylori is a bacterium that lives in various areas of the stomach and duodenum, which can cause mild chronic inflammation of the gastric mucosa and even cause stomach ulcers and stomach cancer.
The infection rate of Helicobacter pylori in the mainland is as high as 59%, and 700 million people are infected by it.
This is mainly related to some usual habits, such as inadequate tableware cleaning, multi-purpose chopsticks, word of mouth when feeding children, and liking to grab food directly with their hands.
Therefore, it is necessary to pay strict attention to personal hygiene in life, and washing hands before meals, using public chopsticks, eating less raw food, etc., can reduce the risk of infection to a certain extent.
drink
The main chemical component of alcohol is ethanol. After drinking alcohol, ethanol will be stored in the stomach, which can thin the gastric mucosa, necrosis and shedding of mucosal epithelial cells, and then cause stomach pain, acid reflux and other symptoms of chronic superficial gastritis.
You can still drink the wine without drinking it
High-salt diet
Pickles, bacon and salted fish, curd milk, etc. are all popular traditional foods, but the commonality of these foods is that the salt content is too high.
The long-term high-salt diet will inhibit the secretion of gastric acid, reduce the resistance of gastric mucosa, and even lead to a series of gastrointestinal diseases such as gastritis, gastric ulcers, and gastric perforation.
Moreover, some high-salt foods also contain a large amount of nitrate, which can be combined with amines in food after being reduced in the stomach to form N-nitroso compounds such as ammonium nitrite with carcinogenic effects, thereby inducing cell malignancy.
Therefore, the daily amount of salt should be less than 5 grams, and pickled and processed foods should be eaten less.
In addition, when buying packaged food, it is best to look at the ingredient list, it is recommended to choose low salt.
Irregular meals
Hunger is the norm for many people. If the three meals are irregular, and there is no fixed time for gastric acid secretion, it is easy to break the normal balance state, resulting in excessive or too little gastric acid secretion, thereby inducing indigestion, acid reflux heartburn, stomach erosion, stomach ulcer and other diseases.
Therefore, it is usually necessary to develop the habit of three meals of regular and quantitative life, and only eat seven or eight points of fullness per meal, which helps to make the stomach's motor pace cells and gastric acid secretion form a regularity, so that the stomach function is more coordinated.
Emotional instability
In life, I often hear people say that "I can't eat my food so much" and "I have stomach pains", etc., in fact, the stomach and emotions are indeed closely related.
The stomach, also known as the "second brain of the human body," is one of the most easily affected by emotions. The data show that 57% to 70% of patients with functional dyspepsia have emotional abnormalities.
Repressive emotions such as anxiety, depression, and fear often lead to low gastrointestinal motility, which can easily lead to loss of appetite, belching, hiccups, early satiety, fullness and other discomforts.
Anger, anger and other more hyperactive emotions can lead to gastrointestinal hyperdynamic reactions, causing gastric acid secretion, gastrointestinal peristalsis increased, inducing gastritis, gastric ulcers, gastroesophageal reflux and so on.
In daily life, everyone should learn to control their emotions, take more deep breaths, listen to music, run and run when they want to be angry or angry, and calm themselves down.
When you are in a bad mood, don't be bored yourself, go out shopping with friends, travel, and relax
Stay up late
According to the research of the Los Angeles Medical Research Institute in the United States, people who often stay up late and lack sleep have a 3 to 4 times the incidence of stomach diseases than the average person! The reason for this is the lack of TFF protein in the stomach of these people.
TFF protein can form a mucous membrane on the gastric mucosa, on the one hand, it can reduce the damage of hard substances to the gastric mucosa; On the other hand, it is weakly alkaline and can effectively prevent the corrosive effect of gastric acid on the gastric mucosa.
Experimental data show that the TFF protein secreted during sleep at night is equivalent to 20 to 30 times the secretion of a day during the day.
Staying up late for a long time, the secretion of TFF protein is reduced, the protection and repair ability of the stomach is weakened, and stomach diseases naturally come to the door. So let's go to bed early
Finally, A reminder to everyone
It is best to have a gastroscopy every year
Especially daily smoking and alcoholism
I like to eat pickled and greasy foods
Or people who have stomach diseases and have a family history of stomach cancer
Be more careful!
