Sure, Brazilian food might be delicious, but for World Cup players it's nothing like the comfort foods of home. 

AP Sports Writer Janie McCauley says the Italian players brought with them prosciutto, olive oil, parmesan and a special tricolore pasta. The U.S. team brought along peanut butter, oatmeal and A1 Steak Sauce and Mexico packed chipotle peppers and the ingredients to make pozole. 

McCauley says that nutrition is vital for World Cup athletes, with Italy and the U.S. putting particular emphasis on planning meals with the help of a dietician or nutritionist.
