Is it true that you can't drink milk on an empty stomach

Drinking milk on an empty stomach is not significantly harmful to most people, but lactose intolerant individuals may experience gastrointestinal discomfort. The protein and calcium in milk can be absorbed normally, but drinking on an empty stomach may affect digestive efficiency for some people. When drinking milk on an empty stomach, the secretion of stomach acid is higher, and the casein in the milk will combine with stomach acid to form clots, which may slow down the gastric emptying rate. Healthy individuals usually do not experience discomfort as a result, but rather can prolong their sense of fullness. The whey protein and immunoglobulin in milk can be directly absorbed by the small intestine, and the calcium absorption rate is not significantly affected by fasting status. It is recommended to pair it with cereal based foods, such as bread or oats, to improve protein utilization and reduce stomach burden. Lactose intolerant individuals who drink milk on an empty stomach are prone to symptoms such as bloating and diarrhea. This group of people lacks sufficient lactase in their intestines to fully break down lactose in milk. Undigested lactose ferments in the colon, producing gas that stimulates increased intestinal peristalsis. For this special population, low lactose milk or yogurt can be chosen, where lactic acid bacteria have already partially broken down lactose. Eating a small amount of solid food before drinking can also help slow down the rate of lactose entering the intestines.

When drinking milk in daily life, attention should be paid to individual differences and observe one's own reactions. The recommended intake of dairy products is around 300 milliliters per day, which can be consumed after meals or with meals. Pairing with fruits rich in vitamin C can help with iron absorption, but avoid drinking it with strong tea to avoid affecting calcium absorption. Special populations such as those with weak gastrointestinal function or postoperative patients should adjust their intake of dairy products under the guidance of a doctor.
