Because coffee has the harm of aggravating high blood pressure and inducing osteoporosis, dietitians do not recommend long-term drinking for the sake of people's health. But a recent survey has rehabilitated coffee, and researchers at Harvard Medical School in the United States report in the new issue of the International Journal of Cancer that people who drink coffee and tea regularly have a lower risk of kidney cancer.

Traditional nutrition holds that drinking coffee in order to refresh yourself when busy helps to improve alertness, agility, memory and concentration. However, excessive consumption will produce stimulants similar to the same dose of stimulants, which can cause nervousness. For people with anxiety disorders, caffeine can worsen symptoms such as sweaty palms, palpitations and tinnitus. Moreover, it will also aggravate hypertension, induce osteoporosis and other diseases, so we are not recommended to drink for a long time.

A recent study came to the opposite conclusion. The researchers analyzed 13 long-term studies on the health effects of various foods and found that drinking coffee and tea regularly reduced the risk of kidney cancer. Drinking milk, soda or fruit juice did not have such an effect.

The researchers found that people who drank more than three cups of coffee a day had a 16% lower risk of kidney cancer than those who drank less than one cup of coffee a day (and did not drink tea), while those who drank only one cup of tea a day (about 230 grams) had a 15% lower risk of kidney cancer than those who did not drink tea (nor coffee).

The researchers point out that although there is no direct evidence that drinking coffee and tea can prevent kidney cancer, some evidence can be found by analyzing the composition of coffee and tea. For example, coffee and tea are rich in antioxidants, which may help protect kidney cells from damage. In addition, some ingredients of coffee and tea can enhance the body's sensitivity to insulin and improve renal function, which may have a certain preventive effect on kidney cancer over time.
