Don't drink milk on an empty stomach, because when eating on an empty stomach, the stomach peristalsis faster, and the nutrients in milk are discharged to the large intestine before digestion and absorption, resulting in a large loss and waste of nutrients. Therefore, it is best to eat steamed bread, biscuits and bread before drinking milk, so that the nutrients in milk can be fully exerted, which is conducive to digestion and absorption.
