Design a short dietary recommendation for a person aiming to increase intake of inulin and resistant starch. Which of the following combinations is most appropriate and why?

• A. Increase fresh-squeezed fruit juices and honey at breakfast because high sugar content guarantees delivery of fermentable inulin and starch to the colon by overwhelming small intestinal absorption.
• B. Use refined white rice cooked hot and served immediately because rapid gelatinization and immediate consumption prevents small intestine digestion and allows intact inulin to bypass absorption into the colon.
• C. Consume extra-lean meats and gelatin-rich broths because proteins and collagen are preferentially converted to resistant starch and inulin during cooking and digestion, delivering them to the colon unchanged.
• D. Add onions and cooked-then-cooled potatoes to meals: onions supply inulin and cooled potatoes increase resistant starch that resists small intestine digestion and reaches the colon for fermentation.

Answer: (D)
