1. What are the key macronutrients and micronutrients that are vital for

the well-being of aging and aged individuals? Provide rationales for each

nutrient's importance in their diet.

Answer: The key macronutrients for aging and aged individuals are

carbohydrates, proteins, and fats, while the essential micronutrients

include vitamins (such as vitamin C, D, and B12) and minerals (such as

calcium, iron, and zinc). These nutrients play crucial roles in maintaining

energy levels, supporting muscle and bone health, and promoting immune

function among older adults.

2. How does the aging process affect an individual's nutritional

requirements? Explain the changes that occur with age, and provide

examples of how nutrition requirements may differ from those of younger

adults.

Answer: The aging process influences nutritional requirements due to

factors such as reduced appetite, decreased absorption and metabolism,

muscle loss, and changes in taste and smell. Older individuals may have

increased protein needs to prevent muscle wasting and require more

calcium and vitamin D to maintain bone health. Additionally, a decrease

in energy expenditure may require adjustments in calorie intake to avoid

weight gain.

3. Discuss the risks and consequences of malnutrition in the aging

population. Explain the link between malnutrition and common health

conditions encountered among the elderly.

Answer: Malnutrition in the aging population can lead to various health

issues, including weakened immune function, increased risk of infections,

impaired wound healing, muscle weakness, and anemia. It can also
