1 Reduce cancer risk
A study published in the American Journal of Clinical Gastroenterology and Hepatology found that drinking coffee every day can reduce the risk of primary liver cancer (the most common type of liver cancer) by 40%. Other studies have shown that drinking coffee regularly can reduce the risk of ovarian cancer in women.
2 Protect the cardiovascular system
After studying 25,000 subjects, Korean researchers found that people who drink 3 to 5 cups of coffee a day (about 200 ml per cup) have a lower risk of cardiovascular disease. A study by the National Cancer Research Center of Japan shows that people who drink 1 cup of coffee every day have a lower risk of death from stroke than those who don't drink coffee.
3 Enhance memory
Moderate intake of caffeine is beneficial to both short-term memory and long-term memory, which helps to prevent cognitive decline.
4 Prevention of diabetes
A study of 6.5438+0.26 million people in Harvard University shows that people who drink coffee regularly have a lower risk of developing type 2 diabetes.
5 contribute to longevity
An academic paper published by a medical professor at Indiana University shows that the death rate of people who insist on drinking coffee is lower than that of ordinary people.
Chengmai County, the hometown of longevity in Hainan, is rich in coffee, with an average life expectancy of 77.79 years, which is 6.59 years longer than the national average. All the long-lived old people here have the habit of drinking pure coffee.

It's healthier to drink coffee like this.
Coffee has many benefits, but it will only be effective if you drink it right.
1 Be sure to choose pure coffee.
If you cook at home, you can buy freshly ground coffee beans, or you can buy coffee powder directly and brew it with hot water.
1 g coffee powder is the best brewing ratio, and 15 ml or 18 ml water is used. People who are not used to drinking pure coffee can put less coffee and add more water to get used to it. If it is difficult to adapt, you can add a little less sugar or fresh milk, but don't add creamer to avoid offsetting the original benefits of coffee.
Hanging ear coffee is also a good choice. Capsule coffee is also very popular now. It grinds coffee beans and puts them into capsules made of special materials, which can be brewed directly with hot water. It is as simple as a tea bag, and it is also called "office coffee" because it saves time. If you drink coffee in a cafe, you'd better choose American coffee without cream and sugar.
Don't exceed 3 cups a day.
People's tolerance for coffee varies from person to person.
After studying caffeine in American dietary guidelines, it is concluded that drinking 3-5 cups of coffee every day is part of a healthy diet for healthy people. Many domestic experts suggest that it is best not to exceed 3 cups per day (about 200 ml per cup).
Morning is the best time.
American neuroscientists have calculated that the best time to drink coffee every day is from 9: 30 am to 1 1: 30 am. This is because caffeine interacts with cortisol, an important hormone in the human body, and reaches the best state during this time.
Need to be reminded that it is best not to drink coffee on an empty stomach or after meals, so as not to affect the quality of sleep.
4 special people should pay attention to the problem
