Dietary counselling of a patient with diabetic gastroparesis includes avoidance of the nutrient that most delays gastric emptying. That nutrient is:
- A Complex carbohydrate
- B Protein
- C Fat ✓
- D Monosaccharides
Correct answer: C. Fat
Explanation
Fat delays gastric emptying more than any other nutrient because duodenal fat releases cholecystokinin, gastric inhibitory peptide, and other enterogastrones that suppress antral motility and increase pyloric tone. Liquids leave fastest, followed by carbohydrate rich meals, then protein, with fat last. This is also why fatty foods worsen symptoms in functional dyspepsia and why fat is restricted in gastroparesis diets.
