You will sweat a lot during exercise, and sweating will consume a lot of elements such as sodium and potassium in your body. Therefore, Peng Zhong thinks bananas are the best exercise fruit, because eating bananas during or after exercise can replenish electrolytes such as sodium and potassium lost in the body in time.
Bananas are also rich in carbohydrates, which can quickly replenish the energy consumed during exercise.
Milk can also supplement protein and calcium, so both can be eaten after exercise. It would be better if the milk is warm.
