In one experiment, people who drank four cups of black tea a day decreased the stress hormone cortisol after six weeks. But it's best not to add milk to tea, which will offset the cancer prevention effect of tea.
In addition, it should be noted that pesticides may remain in tea; Others contain a lot of tannic acid, which is not conducive to blood absorption of iron and leads to 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 buds and leaves of tea trees. White tea has a high antioxidant content, and its disease prevention ability should be stronger than green tea. Antioxidants in white tea have anti-aging effect, which is beneficial to diminish inflammation and prevent several cancers and heart diseases. In addition, white tea can also prevent obesity, and some studies say it can inhibit the growth of new fat cells.
Other studies have shown that the temperature of tea is too high, which easily leads to esophageal cancer. However, there are also studies that women drinking green tea can reduce the incidence of esophageal cancer by 60%.
Is the coffee delicious?
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 suffering from diseases such as liver cirrhosis and liver cancer. Other studies have shown that coffee can enhance the efficacy of painkillers and improve the short-term memory and reaction speed of the elderly.
However, some studies have also found the side effects of coffee, such as reducing blood supply to the heart and discoloring teeth. Studies have shown that women who drink 8 cups of coffee a day are much more likely to give birth to stillbirths. However, it should be noted that the pure coffee with a little milk or sugar is usually used in the above research, which is different from the high-calorie coffee sold in the market.
Which is healthier?
Although some studies have pointed out the adverse effects of tea and coffee, nutritionists do not advise people to give up drinking them. Compared with various soft drinks with high sugar content, tea and coffee are healthier. But everyone should pay attention to those sugary drinks that claim to be coffee. For example, after the latte is added to syrup, the sugar, fat and calories in it all rise sharply. This is no longer a cup of coffee.
In addition, it is generally incorrect to say that tea and coffee will cause dehydration. If you don't drink tea and coffee at first, drinking a lot at once will have adverse reactions, but if you maintain a normal consumption, you don't have to worry about this problem.
The pharmacist warmly reminded us that if we really want to compare, it is difficult for us to make a healthier choice between tea and coffee. Both are very beneficial, and you can choose according to your own preferences.
