Many people know that tea is good for digestion, so they like to have a cup of tea immediately after dinner. They believe that drinking a cup of tea after a meal can not only clean the food residue in the mouth and refresh the breath, but also promote metabolism and help the stomach absorb the nutrients of food quickly, so as to achieve the goal of killing two birds with one stone.
In fact, this idea is wrong, and some people take it for granted. Drinking tea immediately after a meal is not good for your health. It can neither help digest greasy food nor promote nutrient absorption. On the contrary, tannic acid in tea will combine with protein in food to form protein of tannic acid insoluble in water, that is, granular protein appears, which increases the difficulty of absorption and digestion. This is not friendly to middle-aged and elderly people at all, so don't drink tea immediately after meals.
We have mentioned this topic many times. Generally speaking, for healthy people, as long as it is not too strong, drinking tea on an empty stomach is not a big problem. After getting up in the morning, the body consumes a lot of water after a night of metabolism. At this time, adding light tea can really achieve the purpose of replenishing water.
However, it is not a good thing for middle-aged and elderly people to get up early and drink tea on an empty stomach. Because with the growth of age, many middle-aged and elderly people have some common diseases, and their physical functions are declining. If there are these situations, it is best not to get up early and drink tea on an empty stomach, because it will cause tea drunkenness and physical discomfort. Therefore, it is best to drink a cup of warm water in the morning and try not to drink tea.
There are amino acids, caffeine and tea polyphenols in tea, and the latter two are mainly responsible for refreshing the brain. Some people are so excited after drinking a cup of tea that they can't even sleep at night, and they will suffer from insomnia. Therefore, for most people, it is not advisable to drink tea before going to bed.
This is especially true for middle-aged and elderly people. Many people who have experienced it know that the older you get, the shallower your sleep will be. If you can't have a good rest in the limited time at night, you will lose your spirit the next day. In the long run, it will drag down the body and make people unacceptable. Therefore, middle-aged and elderly people should drink less tea at night, so that they can sleep soundly and get up less at night. Speaking of which, by the way, it is best to drink less water before going to bed, so that you can sleep well at night.
The stronger the tea, the more caffeine and tea polyphenols it contains. For the third reason above, the elderly should not drink more strong tea. But in real life, most middle-aged and elderly people are old tea drinkers who drink tea for a long time. The more they drink, the more tea they put in, the more tea they brew and the stronger the tea. The habit of drinking strong tea for a long time cannot be changed.
However, whether from the perspective of health preservation or from the perspective of science, drinking strong tea for a long time is not good for your health. Especially for middle-aged and elderly tea drinkers, they usually drink a lot of tea and have limited economic ability. They are unwilling to sell fresh and tender green tea with high grade and expensive price, so they can only choose coarse and old tea with hundreds of dollars. These teas have less amino acids and high tea polyphenols, which are more likely to increase the burden on the body and are not good for the body.
We are talking about green tea here. As for kungfu tea that can be brewed repeatedly, it is beyond the scope of today's discussion. Of course, even fermented teas such as Pu 'er, white tea, oolong tea and black tea, which can be brewed seven or eight times or even ten times, are not recommended for the elderly to brew repeatedly. Because middle-aged and elderly people drink tea, they can't drink too much at a time. Drinking too much will increase the burden on the body.
Unfortunately, Pu 'er tea, which has just been soaked twice, cannot be directly poured out. On the other hand, I am afraid of being reluctant. If you leave it for too long, even after the night, you can drink it in theory, but considering the realistic environment, it is best not to drink it. No one knows whether there is dust or bacteria.
As for green tea, it can only be brewed two or three times, and then the aroma and taste will change obviously, and the drinking experience will be greatly reduced. It is even better to drink boiled water directly. Green tea is brewed for about 3 times, and more than 90% of the nutrients have completely precipitated. After drinking, there are almost no nutrients.
Therefore, it is not recommended for middle-aged and elderly people to drink green tea all day, let alone change tea five or six times in a row. But depending on the situation, you can change tea after brewing for about three times to get a better drinking experience.
The above are five aspects that middle-aged and elderly people need to pay attention to when drinking tea. In short, middle-aged and elderly people should master five words when drinking tea, namely: early, little, light, appropriate and appropriate.
