Dairy Nutrition and Nutraceuticals — Bridging Health and Functional Benefits
Dairy has been a fundamental component of human diets for centuries, providing essential nutrients such as protein, calcium, vitamins, and minerals. Beyond traditional nutrition, dairy is now recognized as a rich source of nutraceutical ingredients — bioactive compounds that deliver specific health benefits, supporting wellness and disease prevention. From functional proteins and probiotics to bioactive peptides and lipids, dairy-based nutraceuticals are increasingly incorporated into dietary supplements, fortified foods, and functional beverages.
Key Nutritional Components of Dairy
Dairy products such as milk, cheese, yogurt, and whey provide a broad spectrum of nutrients that are essential for growth, metabolism, and overall health:
High-Quality Proteins: Casein and whey proteins are complete proteins containing all essential amino acids. They promote muscle synthesis, recovery, and satiety.
Minerals: Calcium, phosphorus, potassium, and magnesium are vital for bone health, muscle contraction, and enzymatic activity.
Vitamins: Dairy naturally contains vitamins B12, riboflavin, and fat-soluble vitamins A and D, which support energy metabolism, immune function, and bone mineralization.
Bioactive Lipids: Milk fat contains conjugated linoleic acid (CLA) and other bioactive compounds that may promote metabolic health and anti-inflammatory effects.
