Which is a risk of diet restrictions in older adults?

• A. Increased dehydration
• B. Improved palatability
• C. Higher costs
• D. Increased autonomy

Answer: (A)

When older adults are placed on restrictive diets, the chance of not drinking enough fluids increases. Diets that limit certain foods or beverages can reduce overall fluid intake because many high-water foods (like fruits, vegetables, soups) and beverages contribute significantly to daily hydration. Age-related changes—such as a blunted sense of thirst, slower kidney concentration ability, and the common use of medications like diuretics—make older adults more vulnerable to dehydration when fluids aren’t emphasized. By focusing on restricting nutrients without careful hydration planning, dehydration becomes a real risk.

Context notes: while higher costs or greater autonomy can be relevant in other nutrition scenarios, dehydration is the most direct and common risk tied to diet restrictions in this population. To mitigate, pair restrictions with explicit hydration goals, monitor intake and hydration status, and tailor restrictions with a dietitian to maintain fluid balance.
