The Pilgrim Fathers on their way to the New World (s well as the mothers and children) drank it, as it was more healthful than stale, polluted or contaminated water. Cheeers! You could have written a hub on the subject-- though it might already have been done a few times.
Interestingly, studies have shown a "J" curve when it comes to alcohol consumption and health. Those who don't consume alcohol at all have slightly lower health levels compared to those who consume a moderate amount, say 1-2 glasses of beer (or other alcoholic drink) a day. Then the health benefits decline with increased consumption. So a little a day looks to be quite a good thing!
Ok this might be where some of the crazy shows, but here goes. several yrs ago I wanted to lose weight but didn't want to give up my beers, so I went on a beer and salad diet. I did this for about six or eight months...did I lose weight? NOOOOO..(tho I didn't gain any either so it was a wash)
I think a beer or two a day should be fine, especially if you are active and not overeating the rest of the day. I've heard the main problem with beer is that it makes you relaxed, and you stop following your diet.
Best beer to drink to whilst keeping weight I found to be Kilkenny less than 1g of sugar in 400 ml full strength ( that's the luck of the Irish). All come back to calories in vs calories out. Drink in moderation
