2-4 beers a day, every day, drunk slowly and with some food, would only do you good, as it thins your blood and prevents cardiovascular disease, which is #1 killer in US, and the world. If you don't drink at all, you increase your mortality risk by 30-50%, as compared to "moderate" drinking, daily. Moderate means not just 1 beer a day as US defines it, with hidden implication that the second beer is deadly, but instead health benefits extend to about 3-4 beers a day, apparently. And regular drinking (5-7 days a week) is actually better for your health than occasional drinking (1-4 days a week).
See this thread.
Liver damage from drinking beer is actually not easy to achieve. If you drink vodka, scotch or other hard liquor, sure. But you need to drink more than a case of 5-6% ABV beer every day, and down it fast, and do it for decades to get into some real damage territory. Of course it's somewhat variable by person, but overall danger of liver cirrhosis for regular population are a bit overstated. Binge drinking (like what the college kids do), irregular spikes in drinking, high ABV drinks, are generally bad. Regular steady drinking/sipping of low-ABV (5-8%) beverages, with food, is actually good for you. French live longer than most europeans - British, Irish, etc. primarily because of their steady consumption of alcohol - and not just red whine, any alcohol, in fact beer may be better since it is lower in alcohol and has no sulfates.
The more I learn about this, the more I realize how powerful anti-alcohol lobby is at misinforming about risks of drinking (alcohol is a toxin, any amount is harmful, etc.). I know their targets are drunk drivers and perhaps *real* alcoholics, but their efforts may be doing more harm than good, overall - ironically.
