Introduction
Drinking milk on an empty stomach is generally not harmful to the body; however, it is not recommended from a nutritional absorption standpoint. Milk is rich in various nutrients, including protein, fat, vitamins, and certain minerals. When consumed on an empty stomach, milk passes rapidly through the gastrointestinal tract with minimal retention time, thereby impairing nutrient absorption.

Drinking milk on an empty stomach is generally not harmful to the body; however, it is not recommended from a nutritional absorption standpoint. Milk is rich in protein, fat, vitamins, and various minerals. When consumed on an empty stomach, milk passes rapidly through the gastrointestinal tract with very short retention time, thereby impairing nutrient absorption.

Moreover, protein is not preferentially converted into energy for immediate use—carbohydrates and fats are utilized first, with protein serving as an energy source only when the former two are insufficient. Therefore, for healthy individuals, drinking milk on an empty stomach is perfectly safe. However, individuals with lactose intolerance should avoid consuming milk on an empty stomach, as it may readily trigger gastrointestinal discomfort. If you regularly drink milk on an empty stomach without experiencing any adverse effects, you may continue doing so freely. Conversely, if discomfort occurs, consider reducing the amount consumed and gradually building tolerance; alternatively, opt for lactose-free milk.

Whenever possible, it is advisable to consume milk alongside other foods—for example, pairing milk with steamed buns or stuffed buns at breakfast. Avoid consuming milk together with foods high in tannic acid (e.g., strong tea, unripe persimmons), as tannins can interfere with milk digestion and absorption.
