Lot of good responses on here, haven't read each on yet, but here is my take. Probably 2-4 beers a week is best for the average healthy person and I stress healthy, the average person is not healthy. If your abstinent from alcohol, obese and even overweight its almost as bad as being an alcoholic or smoker or worse both. So it depends. 2-6 beers everyday for me is not a good thing. Ideally I should drink that a week-Im workin on it. Right now its 1-3. ( I eat very healthy and my weight is pretty good and exercise 5 days at least a week somehow between an hour or two after work/weekends. Homebrewing really got me into drinking more also exploring craft beer,so Im just an enthusiast. I used to drink more socially like a few+ times a month to get drunk in my younger years but dindnt have a few daily regularly like I do now. I don't believe I should have it every day though and really should have only one or two if I do and maybe ocassionally a few more than that. I just don't get hammered/wasted. Plus I feel pretty awesome if not having any beer or a beer or two the night before,having refreshing sleep the next day.
I agree with the pop drinking too,not to do it,its worthless besides a caffeen buzz. At least with a little coffee there is some health benefit to it. If your drinking both pop/or just eating poorly and more than a few beers your most likely just gaining weight and in turn bad health.
You could also be a person that doesn't drink or only has a few a week,doesnt drink pop exercises regular with good weight but eats a lot of processed bad food and could still be in the same boat as someone who drinks and smokes or is overweight/obese.
I eat great mostly but I do like to go get a piece of pizza or donut every week or ice cream,ocassionally fast food etc.., if your consitant and regular about being conscience about your health then you have control and can know your limits. There have also been studys on brains of people who drank and not drank like a sixer everyday, the results are interesting and proof of health associated with a habbit like that.
