Which dietary modification helps prevent constipation?

• A. Low sodium
• B. No dairy
• C. Low fat
• D. High fiber

Answer: (D)

Raising dietary fiber helps prevent constipation by increasing stool bulk and softening the stool, which stimulates normal bowel movements and speeds stool passage through the colon. Fiber adds bulk that absorbs water, creating a larger, softer stool that is easier to pass. For best results, pair more fiber with adequate fluids and increase fiber gradually to avoid gas or cramping. Good sources include fruits, vegetables, whole grains, legumes, and nuts. The other options don’t directly address stool bulk or transit through the intestines; they’re not established strategies for preventing constipation in the way high fiber is.
