Case-control study reveals higher fat and lower fibre intake in patients with colorectal polyps, highlighting nutritional influences on polyp presence and size.
Key Points
To compare specific dietary habits and nutrient intake between healthy individuals and patients with colorectal polyps of various sizes.
Conducted a case-control study evaluating 108 patients categorized by polyp size—small (≤5 mm, n=26), medium (5–9 mm, n=48), or large (≥10 mm, n=34)—and 35 age- and gender-matched healthy controls.
Assessed dietary intake quantitatively using a consecutive 5-day weighed food record protocol.
Fat intake was significantly higher, whereas intakes of carbohydrates, dietary fibre, and iron were significantly lower in patients compared with controls.
Intakes of vitamin C and calcium were significantly lower among female patients relative to female controls.
