Proteins are particularly critical for recovery from illness in older adults due to their essential role in tissue repair, immune function, and overall maintenance of body structure. As individuals age, the body undergoes physiological changes that affect the ability to synthesize proteins, making adequate protein intake even more important.

Specifically, proteins are comprised of amino acids, which are vital for building and repairing tissues, including muscles and organs that may be compromised during illness. Additionally, they play a significant role in the production of antibodies and other components of the immune system, helping older adults to recover more effectively from infections or surgeries.

In contrast, carbohydrates primarily serve as energy sources, and while they are important for fueling cellular processes, they do not contribute to tissue repair. Fats provide essential fatty acids and energy, but they lack the repair and immune-supporting functions that proteins offer. Sugars, which are a type of carbohydrate, contribute to energy as well but do not provide the necessary structural and functional benefits of proteins needed during recovery.

Therefore, ensuring adequate protein intake is especially vital for older adults to support healing and maintain their overall health during and after illness.
