Milk. White Poison or Healthy Drink?
Milk has been a key part of human diets for thousands of years, especially after humans started farming. While babies naturally digest milk, about 65% of adults worldwide cannot digest much of it due to lactose intolerance, which is more common in some regions like East Asia and less so in Northern Europe. Research shows that drinking a moderate amount of milk (100-250 ml daily) does not increase the risk of cancer or heart disease, and some studies even suggest protective effects. Concerns about hormones, pesticides, and antibiotics in milk are generally unfounded due to very low concentrations or strict regulations. However, milk can cause acne and is a common allergen, especially for children. While milk is a nutrient-rich food, particularly important in regions with food scarcity, it is not essential for healthy adults, and plant-based alternatives like soy milk offer similar nutritional benefits. Milk production also has a significant environmental impact and raises ethical concerns about animal welfare.
