Based on a typical serving, these breakfast cereals entries contribute the most fibre in our database:
Fibre values are approximate estimates, sourced from public food-composition data and, for some UK packaged foods, manufacturer nutrition labels. Actual fibre content varies with variety, brand, ripeness, and cooking method — treat these figures as planning estimates rather than precise measurements. See the Fibre Calculator for further detail on individual foods.
