As individuals age, their nutritional needs change, particularly in terms of caloric intake, protein requirements, and essential nutrients. Older adults often require fewer calories due to decreased physical activity and slowing metabolism, yet maintaining adequate protein intake becomes crucial for preserving muscle mass. Additionally, needs for key vitamins and minerals, such as calcium and vitamin D, increase to support bone health. Hydration needs may also change, as the sensation of thirst can diminish with age. Proper nutrition is essential for managing health conditions and promoting quality of life as one ages.
