Which nutrients are primarily responsible for building and repairing body tissues?

Carbohydrates
Fats
Vitamins
Proteins

The correct answer is: Proteins

Proteins are the primary nutrients responsible for building and repairing body tissues. They are made up of amino acids, which are often referred to as the building blocks of life. Proteins play a critical role in various bodily functions, including the growth and repair of cells and tissues. This is particularly important during periods of growth, recovery from injury, or illness, where the body's demand for protein increases. Carbohydrates primarily serve as a source of energy for the body, while fats are essential for various functions, including energy storage and hormone production, but they do not directly build or repair tissues to the same extent as proteins. Vitamins, on the other hand, are vital for many biochemical functions in the body and can support overall health, but they do not serve as the main elements involved in tissue structure and repair. Thus, proteins are uniquely suited to the role of building and repairing body tissues, making this the correct answer.
