What is a Protein?

Protein is one of three macronutrients and is found in both plant and animal foods. It consists of amino acids, some of which are essential and must be obtained through diet. Protein-rich foods range from meat, fish, eggs, and dairy to plant-based sources like legumes, nuts, seeds, tofu, and tempeh.

Its taste and texture vary widely—animal proteins like chicken are savory and tender, while plant proteins such as lentils have a nutty flavor and a hearty texture. Protein is versatile and can be baked, sautéed, grilled, boiled, or eaten raw in some cases.

Nutritionally, protein is critical for maintaining muscle mass, supporting immune function, and producing enzymes and hormones. Many protein sources are also rich in secondary nutrients like iron, B vitamins, and healthy fats.
