Certified Dietary Manager (CDM) Practice Exam

Question: 1 / 400

Which nutrient is vital for cell repair and growth?

Carbohydrates

Fats

Protein

Protein is vital for cell repair and growth because it is made up of amino acids, which are the building blocks of tissues in the body. When the body sustains damage, such as from an injury or during periods of rapid growth, proteins are essential for the synthesis of new cells and the repair of damaged tissues. This makes protein crucial for maintaining muscle mass, supporting immune function, and ensuring proper cellular function.

While carbohydrates, fats, and vitamins play important roles in overall health and nutrition, they do not primarily serve the specific functions of repairing and growing cells. Carbohydrates are mainly a source of energy, fats provide essential fatty acids and also serve as a concentrated energy source, and vitamins support various biochemical processes in the body. However, when it comes to direct support for cell repair and growth, protein stands out as the most critical nutrient.
