Drinking tea to support the stomach or hurting the stomach is a common topic in the tea industry. Some people say that drinking tea hurts the stomach and some people say drinking tea to support the stomach. Does drinking tea nourish or hurt the stomach?

The stomach is a solid pouch, located in the upper abdomen below the lungs. The wall of this bag is called the stomach wall and consists of 3 layers of tissues. The inner layer is the mucosal layer, the middle is the muscle layer, and the outer layer is the serosa layer. The mucosal layer has gastric glands that secrete mucus, gastric acid, and pepsin. Stomach acid is very acidic. When the bolus enters the stomach, a large amount of gastric acid starts to secrete, which can reduce the pH in the stomach to below 2. Pepsin functions to digest and break down proteins. The mucus acts as a lubricant and isolation, protecting the mucous membrane from gastric acid corrosion and pepsin digestion.

Effects of drinking tea on the stomach:

First of all, drinking tea can replenish water. If the human body is full of water, the mucus secreted by the mucous membrane will be sufficient, and the mucosal epithelium will be better protected.

Second, the pH value of tea soup is mostly between 5.5 and 7, which is weakly acidic. Compared with the strong acidity of gastric acid, it is insignificant. It does not stimulate gastric mucosa and does not neutralize gastric acid.

Third, there is caffeine in tea soup, which has a short-term excitatory effect on the central nervous system, thereby promoting the secretion of gastric juice and gastrointestinal motility, and helping digestion, so people say "drink tea to eat". However, if there is no food in the stomach, too much stomach acid will irritate the gastric mucosa and cause burning or stinging discomfort. Therefore, you should pay attention to avoid drinking tea on an empty stomach.

Black tea warms the stomach ≠ nourishing the stomach

It is rumored that " green tea hurts the stomach, and black tea nourishes the stomach". Many people think that black tea can nourish the stomach, and some people even think that people with poor stomachs should drink more black tea. This idea is wrong.

Some medical experts have said that although black tea is warm, it cannot simply be equated with Yangwei. Although tea polyphenols in tea have great usefulness and have good effects on anti-cancer, tea polyphenols have astringent properties, which can cause irritation to the stomach, especially when fasting. Although black tea is fermented and baked, compared to green tea, the tea polyphenols in it undergo an oxidation reaction during fermentation, the content is reduced, and the stomach irritation is not as strong as green tea.

Therefore, even if the warmth of black tea is consistent with the characteristics of warming the spleen and stomach, it is not suitable for everyone. People with a bad stomach should also be vigilant when drinking black tea, especially if too much black tea is consumed, and a large amount of caffeine will also irritate the stomach. Therefore, black tea has a certain reason to warm the stomach, but it is not the same as raising the stomach.

Protect the stomach, how to drink tea scientifically?

Tea is divided into cold and cold, and there is also a difference between cold and heat in one's physique. Whether tea is nourishing or hurting the stomach depends on the season and also from person to person. If you have a hot constitution and have a lot of fire and gas in your body, drinking more green tea can eliminate fire and detoxification. Then if your stomach is cold, drink cold green tea, drink more warm tea, drink more black tea, and cook more. In addition, patients with stomach problems should never drink tea or beverages immediately after meals. It must take at least 20 minutes before drinking tea or beverages. In addition, it is not advisable to drink tea during meals, which can cause indigestion.
