Which of the following is one of the nutritional problems of the elderly?

  1. Age-induced dysphagia affects digestion

  2. Body's increased need for calcium

  3. Inability to chew food properly

  4. Reduced physical activity affects appetite

The correct answer is: Reduced physical activity affects appetite

The correct response highlights how reduced physical activity among the elderly can significantly impact their appetite. As people age, many tend to engage in less physical activity, which can lead to a decrease in metabolic needs. This reduced activity can result in a diminished appetite, making it more challenging for elderly individuals to consume the necessary nutrients and calories for optimal health. While factors like dysphagia and the ability to chew may also contribute to nutritional issues, the overarching theme of reduced physical activity directly affects many elderly individuals' dietary habits and needs. Additionally, while the body's calcium requirements do increase with age, the focus here is on the immediate relation between activity levels and appetite in the elderly population.
