Like many Czechs (捷克人), Lukáš Berný, 38, enjoys going out to the pub with his friends for conversation and a few beers. “I don’t drink every day,” he says. “I think about three times a week. When I go out, I usually have five to six beers at a time, about the same as my friends.” The beers are half-liters, or 500ml each.

If a half-liter of four-percent beer contains 16g of pure alcohol(酒精), Berný and his friends are drinking 80 to 96 grams of pure alcohol on each outing. The Czech Republic’s National Institute of Public Health, however, suggests that men take in fewer than 24g of pure alcohol per day; women, fewer than 16g.

Medical experts in over 40 countries around the world have agreed that drinking “too much” can cause harm. What they can’t seem to agree upon is just how much is “too much.” National safety levels are quite different, from a limit of 10g a day in the Netherlands to Denmark’s 60g.

There are a number of reasons for this. Dr. Larry Altshuler, a medicine expert for the Cancer Treatment Centers in Tulsa, explains that while everything is based on research, “Every group, race, and gender responds to alcohol differently.”

Also, researchers aren’t using the same models or methods. He adds, “It can be like apples and oranges. How do you measure alcohol? Units, drinks, bottles or cans? What’s the alcohol content(含量)? Is it light or heavy?” While a half-liter of four percent beer contains 16g of pure alcohol, a half-liter of five percent lager contains 20g.

Constance Scharff, a director of Addiction Research at Cliffside Malibu Treatment Center in California, says she believes the reason “is largely cultural.” “But the evidence is clear that the more you drink, the more likely you are to develop alcohol-related health problems.”
