The World Cancer Research Fund (WCRF) has pinpointed the level of drinking implicated in liver cancer after undertaking what it says was the biggest review so far of the evidence on the relationship between diet, weight, physical activity and the disease. Its assessment of 34 previous studies covering 8.2 million people, more than 24,500 of whom had liver cancer, revealed “strong evidence” linking intake of three drinks a day to the disease. “Around three or more drinks per day can be enough to cause liver cancer,” said Amanda Mclean, director of the charity’s UK branch. “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 WCRF’s findings prompted the Alcohol Health Alliance, a coalition of health organisations, to claim that alcohol is so toxic that cans and bottles should carry health warnings. “Alcohol, like tobacco and asbestos, is a class 1 carcinogen and it is totally unacceptable that the public is not provided with such basic information”, said Prof Sir Ian Gilmore, the alliance’s chair.
On the flip side...
The WCRF’s analysis also found strong evidence that coffee could help protect against liver cancer, though it did not specify the amounts someone needs to drink.
if it's right how come we're allowed to buy alcohol
Because substance legality has nothing to do with safety or toxicity. Tylenol is more toxic than MDMA and heroin, and alcohol is far more toxic than marijuana and cocaine.
