Can drinking tea help you lose weight?
The ingredients in tea include: polyphenols, catechins, tannins, caffeine, theanine, phosphorus, etc. Among them, polyphenols, catechins and caffeine have been confirmed in many scientific studies to reduce weight, lower blood lipids and prevent cardiovascular disease. Dietitians said that according to a human experiment on polyphenols and catechins, overweight and obese subjects drank a bottle of high-polyphenols and catechins drinks a day, and after 12 weeks, they found that the average reduction was 1.6 kilograms. The main reason is that catechins can stimulate the sympathetic nerve, promote the body's metabolic consumption and fat oxidation and decomposition, and may also have an appetite-suppressing effect.
What are cold tea making?
Not all tea leaves are suitable for making cold tea! Generally speaking, it is divided into non-fermented tea green tea, yellow tea, partially fermented tea white tea, Baozhong tea, alpine tea, Dongding oolong tea, Tieguanyin tea, Baihao oolong tea, fully fermented tea black tea, black tea, and Pu 'er tea. In terms of characteristics, fully fermented tea will taste more bitter and has no tea aroma, so it is not suitable for cold soaking, while non-fermented tea has no bitter taste and the longer it is soaked, the more fragrant it becomes, so it is more suitable for cold soaking.
If you want to extract the active ingredients when drinking tea, it depends on the temperature, time, tea type and proportion used. Fermented tea is suitable for short hot soaking, and you can obtain glycol tea aroma, tea polyphenols and catechins in a short time. Unfermented tea is suitable for long-term cold soaking. It must be soaked for 12 hours to obtain sweet tea flavor, tea polyphenols and catechins.
Studies have found that the longer tea leaves are warmed, the more caffeine and tannic acid are released, while the caffeine and tannic acid of cold-soaked tea are lower than that of hot-soaked tea leaves. Because too much caffeine and tannic acid can easily stimulate gastric acid secretion, excessive intake will harm the stomach.
To balance healthy tea polyphenols and catechins, and reduce the release of excessive caffeine and tannins, cold soak for more than 12 hours is a good choice. If you want to drink a cup of healthy tea as soon as possible, it is recommended that the water temperature be 60℃ ~ 95℃, and the soak time be about 3 minutes.

To avoid hurting your stomach, what issues should you pay attention to when drinking tea in addition to the temperature? Drinking tea has quite many benefits.
