Re: One little pill?
Alcohol is a natural by-product of the digestion process. The human body has evolved methods of dealing with the toxicity of alcohol - such as alcohol dehydrogenase which is more prevalent in males versus females (https://sites.duke.edu/apep/module-1-gender-matters/content/content-gender-differences-in-alcohol-metabolism/) - hence the advice that men and women should have the same number of units is not based on biology.
It is neither a mutagen nor a promoter and its links to cancer are normally only statistical correlations that frequently have other unhealthy life-style factors associated (heavy drinkers are not known for their healthy eating and exercise plans).
I am very suspicious of all correlation studies as we all should be.
