According to the statistics of the International Coffee Organization, the world consumes 400 billion cups of coffee every year, and 14000 cups are drunk every second. On the other hand, the enthusiasm of the Chinese people for it is not high all the time, and the average person only drinks about 5 cups a year. Coffee is low in calories and contains a variety of nutrients, so drinking it in moderation is good for your health.

One is to reduce the risk of cancer. A study published in the American Journal of Clinical Gastroenterology and Hepatology found that drinking coffee every day reduced the risk of primary liver cancer by 40%. Other studies have said that drinking coffee regularly can reduce the risk of ovarian cancer in women.

The second is to improve memory. Dr. Jack Lin London, senior dietitian at Mount Sinai Hospital in New York, USA, said that moderate consumption of coffee is good for both short-term and long-term memory, helping to prevent cognitive decline.

The third is to protect cardiovascular system. In a study of 25000 subjects, South Korean researchers found that people who drank three or five cups of coffee a day had a lower risk of cardiovascular disease.

The fourth is to prevent diabetes. A study of 126000 people by Harvard University in the United States shows that coffee drinkers have a lower risk of developing type 2 diabetes.

Fifth, it contributes to longevity. An academic paper published by a professor of pediatrics at Indiana Medical University in the United States shows that people who insist on drinking coffee have a lower mortality rate than ordinary people. Chengmai County, the hometown of longevity in Hainan, is rich in coffee, with an average life expectancy of 77.79 years, 6.59 years longer than the national average.

Coffee has many benefits, but it can only be effective if you drink it right. If you make it at home, you can buy coffee beans for fresh grinding, or buy coffee powder directly and brew it in hot water. 1g coffee powder to 15ml or 18ml water is the best brewing ratio, people who are not used to drinking coffee can put less coffee, put more water, gradually adapt. If it is difficult to adapt, add less sugar or fresh milk, but do not add cream. If you drink coffee in a cafe, you'd better choose American coffee without cream and sugar. In addition, do not exceed 3 cups a day.

American neuroscientists have calculated that the best time to drink coffee every day is at 9: 30 / 11 / 30 in the morning. This is because it interacts with cortisol, an important hormone in the human body, and reaches its optimal state during this period of time. Need to be reminded, it is best not to drink coffee on an empty stomach, nor after dinner, so as not to affect the quality of sleep. In addition, pregnant women should reduce their coffee intake, no more than 2 cups a day; patients with high blood pressure should pay attention to the time of drinking coffee and try not to get up early in the morning to avoid a rapid rise in blood pressure.
