A new study has poured cold water on the idea that moderate alcohol consumption is healthy.
Many people enjoy a glass of wine with dinner happily believing that they are reducing the risk of heart disease and helping themselves to live longer.
But now researchers have reassessed the science behind the claimed benefits of drinking within reasonable limits - and concluded that it's flawed.
Many of the 87 studies analysed were found to be poorly designed and biased, suggesting a positive effect when it was likely none existed.
A key issue was the way authors defined "abstainers" who provided the vital comparisons from which conclusions about the health effects of alcohol could be made.
Often, studies compared "moderate" drinkers who consumed up to two drinks per day with "current" abstainers.
However, the abstainer group could include people who had cut out alcohol because of poor health, it was claimed.
"A fundamental question is, who are these moderate drinkers being compared against?" said Dr Tim Stockwell, director of the University of Victoria's Centre for Addictions Research in British Columbia, Canada.
