People who often do manual labor can grow muscles by eating.

First, bananas

Bananas are easily absorbed by the human body and converted into energy. Many athletes will eat bananas to replenish energy in time during the intermission. Eating bananas can quickly replenish lost physical strength.

Second, the staple food

Such as jiaozi, steamed buns, sugar pancakes, meat rolls (noodles, minced meat) and so on. Eat more foods with high calories.

Third, protein.

Protein can not only meet people's physiological needs, but also enhance the resistance to various poisons. It is also important for manual workers to eat more food containing protein.
