Vet ikke om dette er tatt opp tidligere her, men kom over denne artikkelen, som sier at Djokovic i fjor gikk over til et glutenfritt kosthold på grunn av allergi.

"Since Novak Djokovic's nutritionist discovered last year that he was allergic to gluten, the tennis star has switched to a gluten-free diet and is staying away from most processed carbohydrates.
That means no pizza, pasta, pretzels or various other starchy foods that don't necessarily begin with "p." Djokovic made the change last year. Since then he's made the final of the U.S. Open, won the Davis Cup and Australian Open, defeated Rafael Nadal four times, and is currently on a 39-match winning streak, the third longest of the Open era. So much for the idea of a carbo boost."
