Milk is a common nutritional beverage in our lives. It is rich in calcium, which is very helpful for supplementing the body with calcium. Drinking milk daily will not cause "internal heat" (上火), so everyone can rest assured. However, when drinking milk, you should pay attention to whether it has spoiled.
From the perspective of Traditional Chinese Medicine (TCM), milk is considered sweet in taste and neutral in nature, and it has the effect of nourishing the body. The famous ancient medical text "Ming Yi Bie Lu" (《名医别录》) states that milk can "nourish the weak and quench thirst." Classic works such as "Qian Jin Yao Fang" (《千金要方》) and "Ben Cao Gang Mu" (《本草纲目》) also give milk high praise. In regions like Xinjiang and Inner Mongolia in China, people drink milk instead of tea, but they do not experience the problem of "internal heat."
From a nutritional perspective, milk contains substances essential to the human body and has high nutritional value. The calcium rich in milk is particularly praised by nutritionists. Calcium deficiency is a global health challenge. For Chinese people whose diet is primarily vegetarian, the calcium in their food is often interfered with by phytic acid and oxalic acid, making it difficult to absorb, thus leading to a more severe calcium deficiency. Calcium deficiency can lead to osteoporosis and malnutrition.
In recent years, it has also been discovered that the occurrence of hypertension is related to calcium deficiency. The calcium contained in milk is easily absorbed by the human body, making it a nutritious food suitable for all ages. Drinking milk is both appropriate and necessary for your grandmother's condition. The idea that drinking milk causes "internal heat" is an unscientific rumor that should not be mistakenly believed. However, when drinking milk, one must pay attention to food hygiene and not consume spoiled milk.
