With the improvement of health awareness, everyone knows the benefits of drinking tea. In order to replenish water, people generally start to drink a lot of tea or even completely replace boiled water. So, is this way really healthy? Drink water or tea regularly, which is better for your health? Don't make mistakes after reading it!
Let's look at the benefits of drinking water. First of all, drinking water can promote urination, improve metabolism and help waste excrete. Secondly, drinking a cup of warm water in the morning can also promote gastrointestinal peristalsis and play a laxative role; In addition, drinking enough water every day can increase satiety and ensure the normal operation of human organs.
Drinking water every day is necessary, and drinking tea also has many benefits. First of all, tea contains tea polyphenols, which can scavenge free radicals and delay aging. Secondly, drinking tea can also refresh the mind and help to increase vitality; In addition, drinking tea can also accelerate fat burning, which is very helpful for weight control.
It can be said that compared with carbonated drinks and milk tea, whether drinking tea or drinking water is more beneficial than harmful to health, but there is a saying that "everything is toxic and everything depends on quantity". Drinking too much water will lead to "water poisoning" and increase the burden on the kidneys; Drinking too much tea will cause "tea drunkenness" and lead to metabolic disorder.
As far as drinking water is concerned, the Dietary Guidelines for Residents recommends drinking 1.500- 1.700 ml per day. For reference, ordinary bottled purified water is generally 550 ml, that is, about three bottles, and ordinary glass is about 200 ml, which is why it is recommended to drink eight glasses of water every day.
Of course, the amount of drinking water is floating, and with the water in the diet, it can generally reach about 2000 ml. For adults who are engaged in manual labor, it is appropriate to drink more, but it should not exceed 2500 ml, because "water poisoning" may occur if the amount of drinking water is too large.
As far as drinking tea is concerned, it is more important to control the quantity, because the team of Professor Li Liming from Peking University has studied 500,000 people and found that those who drink more than 4g of tea every day will increase the risk of cancer 13%! Even if the data that may be affected are removed, such as people who smoke and drink, people who drink more tea have a higher risk of cancer!
It can be seen that you should pay attention to "degree" when drinking tea. If the quantity is wrong and the method is wrong, the effect may be counterproductive. In this regard, Professor Tu Youyou of Zhejiang University suggested that for adults, 3 grams of tea can be brewed 2-3 times a day, and the total water consumption is about 300 ml, which is the amount of a can.
In addition to drinking tea in moderation, experts also reminded that pregnant women and children should not drink tea, and those with neurasthenia and tachycardia should also reduce the amount of tea. In addition, it is not advisable to drink strong tea or hot tea. Hot tea with a temperature higher than 60 degrees will increase the risk of esophageal cancer, while strong tea contains caffeine, which is easy to cause mucosal damage.
In addition, there are many kinds of tea, including black tea, green tea and oolong tea. As for how to choose, Professor Li Liming of Peking University suggested that drinking green tea every day for healthy people can prevent diabetes, and drinking green tea every day for diabetics can reduce the risk of death! And these benefits are limited to people who drink green tea in moderation!
Coincidentally, the four health drinks recognized by WHO are soybean milk, red wine, green tea and yogurt, among which green tea is impressively listed, which is also very telling. In fact, drinking green tea often can not only delay aging, but also help to maintain beauty, protect teeth and improve eyesight, induce diuresis to relieve fatigue, reduce blood fat and help digestion, which can be described as many benefits.
