Well, the makers of Sam Adams (Boston Beer Company) are apparently like-minded individuals, because they've created a "healthy" beer that's meant to be consumed after a workout! It's called 26.2 Brew, and it's packed with electrolytes to rehydrate you after a tough workout. It's got about the same alcohol level of a light beer (around 5%).
Even if you don't work out, this would be a great beer to drink in the summer! After doing yard work, tailgating at a concert...any place where you'll be getting hot and sweaty, but you still want to drink! BAM!
