How much red wine per week will damage your liver?

Since one of the functions of the liver is to filter out toxins, or what the body perceives to be toxins (such as pain relievers like acetaminophen), any amount of white wine could be considered "damaging" to the liver, as it makes the liver work extra hard to rid the body of alcohol. However, there are benefits to drinking wine, as has been reported in the general media for the last 10 years or so. Possibly the key to avoiding "damage" is a generally healthy diet and occasionally giving the liver a chance to "rest" by not drinking any wine for two or more days, or, if wine is a part of one's usual eating habits, make a point of going a week or two without every so often. Not a doctor, just an opinion.
