Question

5．When you think of what to eat when you're trying to build muscles，fruits may not be the first that comes to mind．But fruits are just as important as any other food．Their potassium（钾）helps make and build muscles，the carbs（碳水化合物）spare your body from burning your muscles for fuel and the antioxidants（抗氧化物）protect the muscles from damage．
Potassium builds muscles．You need enough potassium in your diet to help build muscles．Adults need 4，700 milligrams of potassium a day．Any fruit can help you meet your daily potassium needs，but be sure to include those that are especially good sources，such as cantaloupe，bananas，oranges，kiwifruit，prunes and dried apricots．
Carbs provide your body with energy，and if you don't get enough，your body might burn your muscles for energy instead．The Academy of Nutrition and Dietetics says that Carbs are the major nutrient in fruit and make a healthy choice on your muscle-growing diet．Healthy，high-carb fruits include grapes，pears，cherries，pineapples and dates．
Antioxidants protect muscles．Large amounts of exercise causes chemical reactions that may damage cells，and this may lead you to consider adding antioxidants to your daily routine．But when it comes to antioxidants and health，it's always better to get them from food．Fruits are rich in a number of antioxidants，including vitamin C．Load up on antioxidants to protect your muscles by filling your diet with mangoes，grapefruit，apples and berries．
There are a number of ways you can-add fruit to your muscle-building diet to get all the nutritional benefits．Start by making fruit the sweet ending to your meals．Blend（掺）it up with Greek yogurt to get the nutrients your body needs for refreshment．Fruit also makes．an easy and convenient snack choice．
