A British research team recently reported in the British Medical Journal Open that eating a certain amount of coffee every day can help reduce the risk of liver cancer, and as the intake increases, the risk will be reduced more. This supports the results of previous studies that drinking coffee can reduce the risk of liver cancer.

Researchers from the University of Southampton and the University of Edinburgh explored the relationship between coffee consumption and liver cancer, and the team analyzed data collected from 26 previous studies involving more than 2.25 million participants. Previous studies in the United States and Japan have suggested that drinking coffee can reduce the risk of liver cancer.

The results of the new study show that drinking one cup of coffee a day reduces the risk of liver cancer by 20 per cent, two cups of coffee by 35 per cent, and even by 50 per cent if you drink up to five cups.

According to the team, the effect is the same for people with or without coffee drinking habits, although there is already data showing that the more coffee you drink, the greater the risk reduction, but there is not much data to confirm the effect of drinking more than five cups a day. In addition, even decaffeinated coffee can bring some benefits, but the effect is not so obvious.

The effect of coffee on human health has been inconclusive in academic circles. Previously, the International Agency for Research on Cancer under the World Health Organization listed the habit of drinking hot drinks as a "high risk of cancer" factor, believing that drinking coffee, tea and other hot drinks with temperatures above 65 degrees Celsius may cause esophageal cancer.

Oliver Kennedy, a scholar at the University of Southampton and one of the authors of the report, said the findings are not intended to encourage everyone to drink five cups of coffee a day, but that more in-depth research is needed to analyze the potential harm of consuming large amounts of caffeine. and there is already evidence that some people, such as pregnant women, should avoid excessive consumption of such drinks.
