Coffee can reduce the risk of liver cancer?
Coffee can reduce the risk of liver cancer? A number of studies in the past few years have shown that regular coffee can bring many health benefits. One of the notable benefits is that drinking coffee can reduce the risk of liver cancer.
Not long ago, the New England Journal of Medicine (NEJM), the head of the four major medical journals, published a review paper titled Coffee, Caffeine, and Health. The paper pointed out that a large amount of evidence suggests that drinking coffee does not increase the risk of cardiovascular disease and cancer, and drinking 3 to 5 cups of coffee a day is associated with a reduction in the risk of several chronic diseases.
Among all malignant tumors, the incidence of liver cancer ranks sixth in the world, and the mortality rate ranks fourth in the world. According to the “Global Burden of Disease 2016” data, the number of deaths due to liver cancer worldwide in 2016 was 1,240,201.
Coffee can reduce the incidence of liver cancer, so how will increasing coffee consumption affect the global incidence and mortality of liver cancer?
Recently, a number of research institutions in Australia have collaborated and published a paper titled: Estimates of the global reduction in liver disease-related mortality with increased coffee consumption: an analysis of the Global Burden of Disease Dataset in the Journal of Alimentary Pharmacology and Therapeutics.
The paper analyzed the global burden of disease data set and showed that with the increase in coffee intake, the death rate related to liver cancer decreased globally. Specifically, if everyone in the world drinks at least two cups of coffee a day, The number of deaths due to liver cancer will be reduced by more than 450,000. If everyone drinks at least four cups of coffee a day, the number of deaths due to liver cancer will be reduced by more than 720,000.
Daily coffee consumption per person in various regions of the world
From the statistical data, in Europe, South America, Australia and New Zealand, each person consumes more than 2 cups of coffee per day. Among them, Scandinavia in Europe has the most, with more than 4 cups per person per day. From a global perspective, the average person is less than 1 cup per day.
Researchers found through statistics that drinking two or three cups of coffee a day can reduce a person’s risk of liver cancer by 38%, and the risk of death from liver cancer by 46%. When drinking four cups of coffee a day or more, the risk of liver cancer is reduced by 41%, and the risk of death is reduced by 71%.
Next, the researchers wanted to know what would happen if everyone in the world started drinking two or more cups of coffee a day.
The researchers studied the data in the 2016 Global Burden of Disease data set and extracted statistics related to liver cancer. They found that the number of deaths from liver cancer in 2016 was 1,240,201.
The researchers then searched for statistics on drinking coffee and added these two sets of data to a model that showed the link between drinking coffee and reducing liver cancer. The model shows that if everyone in the world drinks two cups of coffee a day, the number of deaths from liver cancer will decrease by 452,861, and if everyone drinks four cups, the number of deaths will decrease by 723,287.
Therefore, the research team believes that the government and health institutions should start to encourage coffee consumption to reduce the incidence and mortality of liver cancer.
As we all know, China was a major liver cancer country. 55% of the world’s new liver cancers every year come from China, while the total population of China only accounts for 20% of the world’s population. For Chinese people, they prefer to drink tea. Coffee consumption is far less than tea consumption.
Coincidentally, on January 8, 2020, the team of Academician Gu Dongfeng of the Chinese Academy of Medical Sciences Peking Union Medical College Hospital published a paper in the European Journal of Preventive Cardiology. A long-term follow-up study of more than 100,000 healthy Chinese showed that drinking at least a week Three times tea is associated with healthier and longer life expectancy.
These two studies show that whether it is coffee, which is more preferred by Westerners, or tea, which is more preferred by Chinese, drinking in moderation is beneficial to healthy drinking and longevity.
