Milk is a common staple in our daily lives, rich in nutrients that benefit our health. So what are the advantages of drinking milk? Who should avoid it? Let's explore together!
Numerous studies confirm milk's extensive health benefits. For bone health, it plays a crucial role in adolescent skeletal development, particularly in building bone mass.However, there are important considerations when consuming milk!
While many recognize milk's benefits, they may not fully understand its specific advantages. Below, we'll break down these benefits one by one—let's explore them together!
1. Numerous Benefits of Drinking Milk
Milk's nutritional value and contributions to human health have been rigorously researched by countless scientists, yielding substantial evidence that is globally recognized.This is why the third Tuesday of May each year is designated as "International Milk Day."
Of course, this doesn't mean replacing water with milk. Any food, regardless of its merits or drawbacks, must be evaluated within the context of a balanced diet. We advocate for adults to consume one carton of milk daily—a recommendation with significant and practical importance.
2. Milk Boosts Calcium Intake for Stronger Bones
Milk offers numerous benefits, and increased consumption can enhance calcium intake—particularly important for middle-aged and elderly individuals. However, excess in any form is detrimental. Whether drinking milk or adopting other dietary practices, moderation is key in daily life.
Extensive evidence demonstrates milk's broad health benefits for the human body.Regarding bone health, it plays a crucial role in adolescent skeletal development, particularly in accumulating bone mass. The more calcium accumulated in our bones before age 20, the lower the future risk of osteoporosis. For adults, although peak bone mass cannot be altered, milk (especially vitamin A and D-fortified varieties) remains an optimal calcium source and continues to serve a vital function.Milk's rich milk fat content enhances calcium absorption. 3. Enhancing Physical Constitution Beyond calcium supplementation, milk effectively provides protein and trace elements, laying a solid foundation for improving overall nutritional status. Milk protein—comprising casein, small amounts of whey protein, and co-precipitates—boasts an 85% bioavailability, far surpassing the 50%–65% biological value of cereal proteins.Moreover, milk protein contains all essential amino acids required for human growth and development—a quality unmatched by other foods. The ratio of protein to calories in milk is also exceptionally balanced. Milk fat comprises over 500 distinct fatty acids and derivatives, including 66% saturated fatty acids, 30% monounsaturated fatty acids, and 4% polyunsaturated fatty acids, accounting for 48% of total milk calories.Milk fat not only imparts milk's distinctive rich aroma but also aids digestion. Mineral content averages 135mg of calcium per 100g of milk, balanced with phosphorus, potassium, magnesium, and other minerals in a ratio easily absorbed by the body. After reading the above introduction, you should now understand the benefits of drinking milk! But since milk offers such advantages, how much should one consume daily?Let's explore this together!
4. How much milk should you drink daily?
The human body requires daily protein intake, though the amount varies by individual constitution. According to dietary recommendations tailored to the Chinese population by the Chinese Nutrition Society, 1 gram of protein per kilogram of body weight is advised daily. Thus, a 60-kilogram individual needs 60 grams of protein. This amount may fluctuate under specific circumstances.
5. Are you drinking milk correctly?
There's no significant difference in drinking milk at any time of day—it's a matter of personal preference. While some claim "milk before bed aids sleep," this lacks sufficient evidence. The recommended daily intake is 250–500ml (1–2 cartons), with no single serving exceeding 250ml (1 carton).Before drinking milk, consume some staple foods or other animal protein sources (such as eggs). Milk should be the last item consumed at each meal. Drinking milk on an empty stomach causes it to pass through the gastrointestinal tract too quickly, reducing nutrient absorption and potentially increasing the risk of lactose intolerance.Consuming milk after eating other foods prolongs its retention time in the intestines, enhancing nutrient absorption and reducing gastrointestinal discomfort. Pay attention to milk temperature when drinking—ideally between 20–30°C (68–86°F). Avoid consuming it directly from the refrigerator to prevent stomach upset.In fact, some individuals do experience gastrointestinal discomfort or even cramps from consuming excessively cold milk. Milk taken from the refrigerator should be left at room temperature for about half an hour before drinking. Alternatively, it can be boiled and then cooled to a suitable temperature before consumption.
Who Should Avoid Milk?
1. Individuals with digestive tract ulcers should avoid milk.
While milk may temporarily soothe stomach acid irritation on ulcer surfaces, it stimulates the gastrointestinal mucosa to secrete large amounts of gastric acid, potentially worsening the condition.
2. Individuals with iron-deficiency anemia should avoid milk.
Iron from food must be converted into ferrous iron within the digestive tract for absorption. When milk is consumed, the body's ferrous iron binds with calcium and phosphorus salts in milk to form insoluble compounds, impairing iron absorption and hindering recovery in anemia patients.
