A research study conducted by the London, UK-based World Cancer Research Fund International, has revealed that coffee consumption can protect the liver from the damage associated with alcohol consumption. The American Cancer Society estimates that each year in the US there are around 35,660 new cases diagnosed with liver and around 24,550 people that are impacted from liver and duct cancers.
The analyzed data consisted of an analysis of 34 studies that included 8.2 million people; 24,500 of whom had liver cancer. “Around three or more drinks per day can be enough to cause liver cancer, said Amanda McLean, Director of World Cancer Research Fund UK. Until now we were uncertain about the amount of alcohol likely to lead to liver cancer. But the research reviewed in this report is strong enough, for the first time, to be more specific about this.”
The findings were published in the Continuous Update Project (CUP) 2015 report on “diet, nutrition, physical activity and liver cancer.” They are based on an analysis of 34 studies that included 8.2 million people – more than 24,500 of whom had liver cancer.
A summary of these findings revealed that one cup of coffee was sufficient to confer a protective cup of coffee. Both coffee and coffee extracts have also been shown to reduce the expression of genes involved in inflammation, and the effects appear to be most pronounced in the liver. There is evidence from small intervention studies that coffee consumption reduces DNA damage in blood cells and prevents ex vivo-induced DNA damage in healthy volunteers. Specifically, the study determined that the risk of developing liver cancer might be reduced by approximately 14% if individuals consume one cup of coffee per day.
The evidence for coffee was generally consistent, and the dose-response meta-analysis showed a significantly decreased risk of liver cancer per one cup per day.
