Why dairy products still belong in your balanced diet, according to science

Dairy products remain a key part of a balanced diet, according to health experts. The U.S. Department of Agriculture advises adults to consume around three servings daily. New findings highlight how milk and other dairy items support bone strength, muscle health, and even weight management. Pasteurized cow’s milk stands out as one of the most nutrient-rich options compared to plant-based alternatives. A single 240 ml glass delivers 8 grams of high-quality protein along with 13 essential vitamins and minerals. These nutrients include calcium, phosphorus, and vitamin D—all vital for maintaining strong bones and teeth.

Regular dairy intake has been linked to a lower risk of bone loss, osteoporosis, and osteopenia, particularly in older adults. The calcium in milk may also play a role in fat breakdown, reducing its absorption and helping people feel full for longer. Additionally, one serving can provide about 60% of the body’s daily iodine needs, which supports thyroid function and fetal development. Research suggests that moderate consumption of whole milk may contribute to lower body weight and a reduced BMI in adults. Beyond bone health, milk’s protein content helps preserve muscle mass and aids recovery after exercise.

The USDA’s guidelines reinforce dairy’s importance in daily nutrition. With benefits ranging from stronger bones to better muscle recovery, milk remains a simple yet effective dietary choice. Nutritionists continue to recommend it as a healthier option over many plant-based substitutes.
