Which dietary component is important for healthy nail growth?

• A. Carbohydrates
• B. Fats
• C. Protein
• D. Fiber

Answer: (C)

Protein is essential for healthy nail growth because it provides the necessary building blocks for the production of keratin, the primary structural protein that makes up the nails. Keratin is crucial for maintaining the strength and integrity of nails. As nails are primarily composed of this protein, an adequate intake of dietary protein supports overall nail health by promoting growth and preventing brittleness or weakness.

Additionally, proteins are made up of amino acids, some of which are necessary for new cell formation and growth, including in the nail matrix, where nail growth begins. A diet rich in protein sources—such as meat, fish, eggs, and legumes—ensures that the body has sufficient materials to produce healthy, strong nails. Therefore, the role of protein in nail health is significant and directly impacts their condition and appearance.
