If a 12 oz. regular beer has about 150 calories, I see no great harm in drinking one beer per day, assuming you don't graduate to Alcoholism. However, with 2 beers we're talking 300 calories and that could be the beginning of building a beer-belly. A beer-belly means the person can't take the extra calories. Too many calories from beer displace healthier whole foods.
Note: Beer is a processed food so it's off my list.
