Some studies say that tea may prevent type 1 diabetes, reduce the risk of heart attack, prevent obesity, coronary heart disease, cancer, etc.
In one experiment, people who drank four cups of black tea a day experienced a decrease in the level of the stress hormone "cortisol" in their bodies after 6 weeks. However, it is best not to add milk to tea, which will counteract the cancer-preventing function of tea.
In addition, it should be noted that there may be pesticide residues in tea; Some contain a large amount of tannins, which is not conducive to the absorption of iron into the blood, resulting in anemia.
Regarding the choice of tea, most people think that green tea is the most beneficial to health, but those who really understand tea prefer white tea, which is made from the young shoots and young leaves of the tea tree. White tea is higher in antioxidants and is supposed to be stronger at preventing disease than green tea. The antioxidants in white tea have anti-aging effects, which are beneficial for anti-inflammatory and prevention of several types of cancer and heart disease.
In addition, white tea can also prevent obesity, and some studies say that it can inhibit the growth of new fat cells.
There are also studies that show that too high the temperature of tea can easily lead to esophageal cancer, but there are also studies that say that drinking green tea in women can reduce the incidence of esophageal cancer by 60%.
Good coffee? Coffee can prevent type 2 diabetes, reduce the risk of gout in middle-aged men, inhibit the development of Alzheimer's disease, and prevent men from developing liver cirrhosis, liver cancer and other diseases. There are also studies that say that coffee can enhance the efficacy of painkillers and improve short-term memory and reaction speed in older adults.
However, there are also studies that have found the adverse effects of coffee, such as reducing the blood supply to the heart and discoloring the teeth. Studies have shown that women who drink 8 cups of coffee a day have a much higher chance of having a stillbirth. However, it is important to note that the studies used in these studies are usually pure coffee with a little milk or sugar, which is different from the high-calorie coffee sold in the market.
Which is healthier, exactly?
Although some studies have pointed out the adverse effects of tea and coffee, nutritionists do not recommend that everyone give up drinking them. Compared to a variety of soft drinks with a high sugar content, tea and coffee are healthier. But beware of sugary drinks that claim to be coffee.
For example, when you add syrup to a latte, the sugar, fat, and calories in it rise dramatically, and it's not a cup of coffee.
Also, it is not correct to say in general terms that tea and coffee cause dehydration. If you don't drink tea and coffee and drink a lot of it at once, you will have an adverse reaction, but if you keep drinking a normal amount all the time, then you don't have to worry about this problem.

Tea contains a large amount of oxalic acid, which is easy to chemically react with the calcium excreted in the urine to form calcium oxalate, which in turn causes urinary stones. At the same time, the tea tree will be sprayed with pesticides during the growth process, and the pesticides are easy to remain on the surface of the tea leaves, and the untreated tea leaves are easy to carry residual pesticides.
Therefore, washing tea is a necessary procedure before drinking tea, and there is also a saying in life that "do not drink the first tea". Drinking tea on an empty stomach can also cause people to feel dizzy, flustered, and in a trance.
