Age-related changes can significantly affect dietary needs due to shifts in metabolism, muscle mass, and overall health. As individuals age, their metabolic rate tends to decrease, often requiring fewer calories while still needing essential nutrients for overall wellness. Bone density may decline, leading to an increased need for calcium and vitamin D. Additionally, older adults might benefit from more protein to support muscle maintenance. Consequently, adapting dietary choices to meet these changing needs is vital for sustaining health and function in later years.
