In counseling older adults about nutrition, which statement is correct?

• A. Older adults are more prone to dehydration than younger adults are.
• B. Older adults need the same amount of most vitamins and minerals as younger adults do.
• C. Many older men and women need calcium supplementation.
• D. Older adults should consume a diet low in carbohydrates.

Answer: (A)

Older adults are more prone to dehydration because aging brings less total body water, reduced kidney concentrating ability, and a blunted thirst mechanism. Medications (like diuretics), chronic illnesses, and functional limitations can further decrease fluid intake or increase losses, so even mild illness or hot weather can lead to dehydration. In counseling, focus on establishing a regular fluid pattern, offering fluids throughout the day, and teaching caregivers and the older person to watch for signs such as dry mouth, dark urine, dizziness, or confusion. Tailor advice to any conditions that affect fluid balance, such as heart failure or kidney disease, and emphasize practical strategies—drinking with meals, a variety of fluids, and assistance with intake as needed. Since thirst is not a reliable sole indicator in older adults, proactive hydration support is essential. Regarding the other statements: older adults often need more of certain nutrients (for example, calcium and vitamin D) and may experience decreased absorption or higher requirements, so they aren’t guaranteed to need the same amounts as younger adults. Calcium supplementation is common but not universal; the need should be evaluated individually. A diet low in carbohydrates is not typically recommended; older adults benefit from a balanced diet with adequate, nutrient-dense carbohydrates.
