　　Some athletes eat strange foods that improve their performance. Yohan Blake the Jamaican sprinter and 100－meter world champion has stolen champion sprinter Usain Bolt's thunder on the track during the Olympic trials. Asked about how he gets his energy Blake answered that he eats 16 bananas per day Glassman said.
