What role do carbohydrates play in the diet of the elderly according to the guidelines?

Carbohydrates are a primary source of energy for the body, which is especially important for the elderly as they often require energy to maintain their daily activities and overall health. With age, energy needs may shift, but the need for a steady supply of energy remains essential for conducting daily tasks and participating in physical activities, which can help improve quality of life. This energy comes primarily from carbohydrates, which are easily converted into glucose, the body's preferred fuel source.

While carbohydrates do play roles in other functions, such as indirectly supporting muscle repair through energy provision needed for physical therapy or exercise, they are not as directly involved in those processes compared to proteins. The same goes for organ function and skin health, where other nutrients, particularly proteins, lipids, vitamins, and minerals, play more significant roles. Therefore, emphasizing carbohydrates primarily as an energy source for daily activities is most aligned with their critical function in the diet of the elderly.
