I have NASH and when I was going through my initial consultations about it I was asked to monitor my usual alcohol consumption for a month. I was worried because I thought I drank a lot, but I charted it honestly and took it in expecting the worst.
My consultant took one look and just glossed past it and moved on. I asked them how come and they said I was at less than a quarter of the threshold for alcohol-caused liver disease.
That blew my fucking mind, because I was keenly aware of the prevalence of alcohol-related diseases and I honestly didn't feel like I was a particularly responsible drinker then — but you have to be really really REALLY committed to alcohol abuse to hit the threshold, and yet huge numbers of people are.
