Protein meaning

Protein is a macronutrient that is essential for building and repairing tissues, producing enzymes and hormones, and supporting overall growth and development. It is made up of amino acids, which are the building blocks of the body's cells and tissues. Dietary sources of protein include meat, dairy products, fish, eggs, beans, legumes, nuts, and seeds. Adequate protein intake is crucial for maintaining muscle mass, supporting immune function, and promoting healthy skin, hair, and nails. Protein needs vary based on factors such as age, sex, activity level, and overall health, with higher requirements during periods of growth, illness, or intense physical activity.
