You posted a link to an article about liver damage in heavy drinkers and alcoholics. This group of people would have little hope of controlling their alcohol intake without assistance and their drive for alcohol is not going see them making their own beer. That is, think about the preferred method of alcohol intake for these people and you will realise that homebrewers are unlikely to be alcoholics.
Ridiculous comment.
Lets face it, alcohol is a poisonous substance that stresses your body's resources for metabolising the toxins and I'm not advocating the use of poisons but to suggest to moderate drinkers that taking a month off drinking alcohol would decrease the incidence of cirrhosis is just nonsense, when the risk is so low.
Have your AFD's, AFM's and jolly yourself into thinking you are doing something healthy, then destroy all the hard work by returning to your usual consumption. If you are worried about the damage that alcohol is doing to your body, there is only one way to get peace of mind...
