Mary Jane Ashley, professor of public health sciences at the University of Toronto, says that the "weight of evidence in favor of protection is now substantial," but stressed that alcohol's protective effects against coronary disease is related only to very modest levels of consumption -- "as little as one drink every two days," she says.There are no additional benefits for higher levels of consumption, adds Ashley, and in fact, the risk of other problems -- including cirrhosis, cancer, stroke, accidental injury, and perinatal difficulties -- have been proven to increase along with consumption.
Ashley points out that alcohol's protective affects have primarily been proven in certain subpopulations, especially for middle-aged men with a high risk of heart disease.Nonetheless, she and other advocates argue, the alcohol industry has been quick to seize upon the data and extrapolate the benefits to the population at large.

Ashley noted that Canada's Low-Risk Drinking Guidelines call for a maximum of two alcoholic drinks daily, up to a maximum of nine weekly for women and 14 weekly for men.
The Canadian guidelines stress that while drinking is an individual choice, it is a risky one; that the guidelines describe maximums, not targets for drinkers; that alternative means to drinking are available to reduce the risk of heart disease, such as diet and exercise; and that drinkers should contact a doctor if they are having a problem with alcohol consumption.
Unfortunately, a 1997 survey showed that many Canadians drink in excess of the recommended limits, says Ashley.
