Buzz·Posted on Aug 14, 2016This Is Why Olympians Bite Their Medals In PhotosGold medals are actually made of chocolate! (JK.)by Jessica MisenerBuzzFeed StaffFacebookPinterestTwitterMailLink You've probably seen a million, billion, gazillion photos of Olympians biting down on their new medals. Laurence Griffiths / Getty Images Yum, tasty snack...? And it's not a new phenomenon, either. Gray Mortimore / Getty Images This is the 1991 Great Britain track-and-field team. So why does everyone chomp down on their medal like it's a stick of beef jerky? Al Bello / Getty Images Clive Owen / Getty Images Damien Meyer / Getty The answer is that the photographers pretty much force them to (lol). Eric Feferberg / AFP / Getty Images “It’s become an obsession with the photographers,” David Wallechinsky, the president of the International Society of Olympic Historians, told CNN. “I think they look at it as an iconic shot, as something that you can probably sell. I don’t think it’s something the athletes would probably do on their own.” Because you can only have so many dorky photos of medalists just standing there and smiling, right? Martin Meissner / AP And of course, one historic way to tell if gold is real is to bite down on it. Heritage Auctions / Wikipedia / Via en.wikipedia.org Your teeth will leave marks in real gold, which is soft. (Psssst: The gold medal is actually made mostly of silver.) Pascal Le Segretain / Getty Images Rio's gold medals, like all gold medals since 1912, aren't made of solid gold. (They're only about 1.2% gold this year.) Biting your medal can be hazardous. In 2010, German luger David Moeller (left) chipped his front tooth while biting his silver medal for photographers. Alberto Pizzoli / AFP / Getty Images Yeah, it's a pretty weird tradition. Carl De Souza / AFP / Getty Images Some Olympians choose to kiss their medals instead.
