It is ok to eat bread and milk in the morning. Bread is mainly flour and rich in carbohydrates, which can promote metabolism and replenish abundant energy for human body. Milk is rich in protein, amino acids and calcium ions, which can increase satiety when mixed with bread. But be careful not to eat too much, because too much intake of protein in milk may lead to drowsiness, and the throat may be sticky after drinking too much milk, which is not conducive to a day's work.
