For infants and children with gastroenteritis, which dietary recommendation is appropriate?

• A. Avoid caffeine-containing beverages
• B. Avoid bananas
• C. Avoid whole grains
• D. Drink citrus juice

Answer: (A)

In gastroenteritis, the priority is preventing further dehydration while rehydrating. Caffeine-containing beverages can worsen fluid loss because caffeine acts as a mild diuretic and can increase GI motility, leading to more stooling and greater fluid loss. Keeping fluids free of caffeine helps support rehydration and recovery, making this the best choice.

Beyond hydration, use oral rehydration solutions and age-appropriate foods as tolerated. Bananas are bland and can help with potassium, while whole grains and citrus juice aren’t universally contraindicated but aren’t needed specifically to avoid dehydration. The main idea is to minimize fluids that can worsen dehydration, with caffeine-rich drinks at the top.
