The nurse is teaching a patient about dumping syndrome and food choices. Which of these foods would the nurse instruct the patient to avoid?

A. Coffee with sugar and a glazed donut: High-sugar foods and caffeine can trigger dumping syndrome by rapid gastric emptying and fluid shifts into the intestines. B. Jello: While it contains sugar, Jello is often tolerated in small amounts and does not have the high glycemic load of a donut and sweet coffee combination. C. Spinach and avocado salad: This is nutrient-dense and low in simple sugars, which makes it acceptable. D. Eggs and toast: A high-protein, low-sugar option that is generally recommended for clients with dumping syndrome.
