Protein, a powerful macronutrient like carbohydrates and fat, is a fundamental, structural and functional element of every living cell of the body, which plays an essential role in a wide range of metabolic interactions. In addition, our body utilizes this nutrient to build, repair and maintain several tissues and to make important enzymes, hormones, and other body chemicals.
Protein is an important building block of bones, muscles, cartilage, skin, and blood. Our hair and nails are mostly made of protein. Thus, it is very crucial for all of us to maintain an adequate protein intake in the diet during our lifetime, particularly as we get older.
