What are the potential drawbacks of drinking too much milk?

In daily life, many people enjoy drinking milk to supplement essential nutrients required by the body. However, for some individuals, excessive consumption may instead impose a burden on their health. So, what are the potential adverse effects of drinking too much milk?

Adverse Effects of Excessive Milk Consumption

1. Impaired gastrointestinal function: Individuals with lactose intolerance may experience bloating, abdominal pain, and diarrhea after consuming plain (unfortified) cow’s milk.
2. Increased renal burden: Plain cow’s milk is rich in protein; thus, patients requiring protein restriction (e.g., those with chronic kidney disease) should limit their intake.
3. Elevated fat and caloric intake: Compared with plain water, plain cow’s milk contains appreciable amounts of calories and fat; therefore, individuals with obesity or diabetes should consume it in moderation.

Plain cow’s milk is an excellent source of high-quality protein that is easily digested and absorbed. Its fat and lactose content provide energy necessary for normal bodily functions. Additionally, plain cow’s milk contains L-tryptophan, an amino acid known to promote better sleep. Individuals experiencing poor sleep quality may benefit from consuming a small amount of plain cow’s milk before bedtime to improve sleep. According to Traditional Chinese Medicine (TCM), plain cow’s milk has a neutral thermal nature and offers benefits such as promoting body fluid production, relieving thirst, tonifying deficiency, strengthening the body, fortifying the spleen, and nourishing the stomach. For individuals with calcium deficiency, consuming plain cow’s milk alongside appropriate treatment of the underlying condition may help enhance therapeutic outcomes.

Although milk is highly nutritious, overconsumption should be avoided to prevent potential harm to health. We hope this information proves helpful to you!
