i'm no scientist, but i can tell you my beverage of choice after a work-out has always been beer well, maybe not always but for sure since my first ever rugby match i was told beer has electrolytes in it so i figured that's why i crave it after a hard game or a long run but maybe, just maybe there's more to it and apparently the more to it also makes it good for me!! yay - i love when i get told by sciencey people that beer is good for me! new research says drink wheat beers after a marathon its all in the polyphenols!
