Phospholipids are fascinating natural compounds that occur in many foods, including milk, dairy products, eggs, meat, seafood, and plant-based foods. Although they are present in relatively small amounts, their importance extends far beyond their quantity. Dairy phospholipids, particularly those associated with the milk fat globule membrane, possess unique nutritional and functional properties and are attracting increasing attention for their potential roles in brain health, gut health, lipid metabolism, and overall well-being. They also act as natural emulsifiers, making them valuable ingredients for developing innovative and functional foods. This article explores the major dietary sources of phospholipids, with special emphasis on dairy sources, their key health benefits, and their growing applications in the food and health sectors. Understanding these naturally occurring ?hidden treasures? of milk can open new avenues for their sustainable utilization and value addition. Dairy phospholipids represent a promising link between nature, nutrition, and the future of functional foods.
