Some studies have found that whether it is virus, alcohol, drugs or other factors, habitual drinking coffee can protect liver cells from damage and reduce the risk of abnormal liver function, liver cirrhosis or liver cancer. In cytological studies, it has been found that caffeic acid can inhibit the proliferation of hepatitis C virus, but some studies have also found that drinking coffee has no effect on viral hepatitis such as hepatitis A, B or C.

The reason why American coffee can reduce the deterioration of liver disease may be that drinking coffee is less likely to develop diabetes, which is closely related to liver disease, such as fatty liver. There is also a corollary that coffee can reduce inflammation in the body and slow inflammation of the liver, thus reducing the incidence of liver fibrosis and cirrhosis. The third corollary is that coffee has an antioxidant effect, which helps to reduce the damage to the liver.

In addition, in animal studies in mice, caffeine has been shown to inhibit liver cancer. In addition to caffeine, a variety of compounds in coffee, including diterpenes and polyphenols, may also have some effects, but further studies are needed.

Japan has conducted a study on 90,000 urban population of Tokyo and found that there is a dose relationship between drinking coffee in patients with hepatitis B and C and reducing the risk of liver cirrhosis and hepatitis. Drinking 1 cup of coffee a day can reduce the risk of liver cirrhosis and hepatitis to 78%. Drink 2 cups of coffee, the risk is reduced to half, if you drink 4 cups of coffee a day, the risk can be reduced to 25%.

Lightly roasted American coffee has a better effect on liver protection.

Swedish research speculates that the reason may be chlorogenic acid in raw coffee beans, but chlorogenic acid decreases with baking temperature, so drinking heavy-roasted and decaffeinated coffee may not be effective if you want to protect the liver. The content of chlorogenic acid in coffee is related to the way of brewing. The content of chlorogenic acid in American coffee is the highest, followed by Italian coffee, siphon coffee, and finally ice drop coffee.

Drinking American coffee helps to reduce gallstones

The epidemiological study of coffee in gallstones has not been determined. Zhang et al conducted a systematic review and analyzed a case-control study and five prospective generations of 227749 participants and 11477 cases of gallstones. Among them, prospective studies found that coffee significantly reduced the risk of gallstones in women, but not in men, but no relationship between coffee and gallstones was found in this case-control study.

However, in dose response (dose-response) analysis, it was found that compared with those who drank the least coffee, those who drank 2, 4 and 6 cups of coffee per day had a relative risk of cholelithiasis of 0.89 (95%CI 0.79-0.99), 0.81 (95%CI 0.72-0.92) and 0.75 (95%CI 0.64-0.88), indicating that drinking coffee reduced the risk of gallstones. (among them, the relative risk value is less than 1.0, which means that the risk is low, and the 95% confidence interval does not exceed 1.0, indicating a statistically significant difference, and the probability [p] value will be < 0.05. )
