Sandy Hutchens Cancer Prevention – Researchers from McGill University in Montreal surveyed nearly 3,600 Canadian men aged 35 to 70 and found those who averaged at least a drink a day had higher risks of a number of cancers than men who drank occasionally or not at all.
These included cancers of the esophagus, stomach, colon, lungs, pancreas, liver and prostate.
When the researchers looked at individual types of alcohol, though, only beer and “spirits” — and not wine — were linked to elevated cancer risks.
In general, the odds increased in tandem with the men’s lifetime alcohol intake, according to findings published in the Cancer Prevention and Detection. With several cancers, men who drank at least once a day tended to have higher risks than those who drank on a regular, but less-than-daily, basis.
When it came to esophageal cancer, for instance, men who had a drink one to six times per week had an 83 per cent higher risk than teetotalers and less-frequent drinkers, while daily drinkers had a three-fold higher risk.
In addition, when the researchers looked only at daily drinkers, the risks generally increased with the number of years the men had been drinking daily.
“Our results show that the heaviest consumers over the lifetime had the biggest increases in the risks of multiple sites of cancer,” researcher Dr. Andrea Benedetti told Reuters.
Many studies have suggested that moderate drinking — usually defined as no more than a drink or two per day — can be a healthy habit, particularly when it comes to heart disease risk.
But the current study suggested that even such moderate drinking levels are linked to higher risks of certain cancers, at least when the alcohol of choice is beer or liquor.
The question of whether moderate drinkers should cut down, however, cannot be answered by a single study.
The Science Behind Beer and Health
October 2006 (Medialink) – Who knew that beer may help reduce the risk of heart disease and certain other chronic diseases related to aging? According to a professor of medicine and public health at the Boston University School of Medicine, it may. Dr. Curtis Ellison spoke at a conference on a panel called, “Beer: To Your Health!,” held by the Center for Food, Nutrition and Agriculture Policy at the University of Maryland-College Park. This conference reviewed the science on health benefits of moderate beer and alcohol consumption and the challenges of communicating a balanced message to the public.
Brewed from barley, malt and other grains, some studies suggest that beer may have heart-healthy benefits and that older adults who consume moderate amounts of alcohol may have a lower risk of heart disease, stroke, diabetes, dementia, osteoporosis – and maybe even obesity.
The key is moderation. U.S. dietary guidelines define “moderation” as one drink per day for women, and two for men. Experts say that for those who choose to drink, alcohol should be consumed with food – and that the total number of alcoholic drinks should not be averaged out for the week. That means people should not save their ‘drink a day’ all week and then have seven drinks on Saturday night.
