Pasteurized milk is a rich source of calcium, which is crucial for healthy bone and teeth development. Calcium helps in maintaining strong bones and preventing conditions like osteoporosis. The high-quality protein in milk supports muscle growth and repair, making it beneficial for athletes, bodybuilders, or anyone looking to increase muscle mass. It contains immune-boosting nutrients such as vitamins A, D, and B12, which help support the immune system. Fresh cow milk also contributes to healthy skin, as vitamins and minerals like vitamin A promote skin health and may help prevent dryness or acne. Due to its high water content, milk helps keep the body hydrated and replenishes fluids lost during exercise or hot weather. The calcium, phosphorus, and vitamin D in milk work together to promote bone health and prevent bone loss as we age. The probiotics and enzymes in milk, particularly in fermented forms like yogurt, aid in digestion and improve gut health. Finally, some studies suggest that the proteins in milk can help control appetite and support weight management when included in a balanced diet.

Pasteurized milk primarily consists of water (about 87%). It contains proteins (casein and whey), fats (saturated and unsaturated), and lactose, the main carbohydrate. Milk is rich in vitamins, including A, D, B12, riboflavin, and K, as well as minerals like calcium, phosphorus, magnesium, and potassium. Additionally, it contains enzymes that aid in digestion and nutrient absorption.
