In advising older adults about energy intake, which statement is reflected in the material?

• A. Older adults are more prone to dehydration than younger adults are.
• B. Older adults require more calories than when they were younger.
• C. Older adults should follow a zero-fat diet.
• D. Nutritional needs do not change with age.

Answer: (A)

Older adults have a higher risk of dehydration because aging brings changes that reduce total body water, blunt the thirst sensation, and can impair the kidney’s ability to conserve water. Medications (like diuretics), chronic illnesses, and functional limitations can further increase this risk. Because fluids contribute to overall nutrition and energy balance, guidance about energy intake in older adults naturally includes attention to staying adequately hydrated. This is why the statement reflecting material is that older adults are more prone to dehydration than younger adults. In contrast, caloric needs typically decline with age due to lower basal metabolism and activity, fats are an important energy source and essential in the diet, and nutritional needs do change with age, so a zero-fat approach or assuming no change in needs would not be appropriate.
