It's more exciting in the abdomen. Black tea is different. It is made by fermentation and baking. Under the action of oxidase, tea polyphenols undergo enzymatic oxidation reaction, and the content decreases, thus reducing the stimulation to the stomach. Black tea not only won't hurt the stomach, but also nourish it. Drinking black tea with sugar and milk often can diminish inflammation, protect gastric mucosa and have a certain effect on treating ulcers.
General preventive measures
The newer the new tea, the better. Improper drinking can easily hurt the stomach. Because new tea has just been picked, it has a short storage time and contains more unoxidized polyphenols, aldehydes and alcohols, which has little effect on healthy people. But for patients with poor gastrointestinal function, especially those with chronic gastrointestinal inflammation, these substances will stimulate gastrointestinal mucosa, and people with poor gastrointestinal function are more likely to induce stomach diseases. Therefore, it is not advisable to drink more new tea, and do not drink new tea that has been stored for less than half a month. In addition, new tea also contains more caffeine, active alkaloids and various aromatic substances, which will also excite people's central nervous system. Patients with neurasthenia and cardiovascular and cerebrovascular diseases should drink it in moderation, not before going to bed or on an empty stomach. The correct way is to leave it for half a month before using it. Don't take medicine with tea; Do not drink tea before and after taking the medicine 1 hour. Ginseng and American ginseng should not be eaten with tea. Avoid drinking strong tea to relieve hangover; It is not advisable to drink tea before meals; Avoid drinking tea immediately after meals; Girls should avoid drinking strong tea.
It is best to drink black tea often in winter.
When people drink green tea instead of eating, they will feel sick to their stomachs. This is because tea polyphenols, an important substance contained in tea, have astringent taste and have a certain stimulating effect on the stomach, especially on an empty stomach. Black tea is fermented and baked, and tea polyphenols are enzymatically oxidized under the action of oxidase, so the content is reduced and the irritation to the stomach is also reduced. Black tea not only won't hurt the stomach, but also nourish it. Drinking black tea with sugar and milk often can diminish inflammation and protect gastric mucosa, and also has a certain therapeutic effect on ulcers. However, black tea is not suitable for cold drinking, which will affect the effect of warming the stomach, and may also reduce the nutritional content because it is left for too long.
