The reduced availability of food energy from fibre is already accounted for in at least Canada's food labeling rules: https://inspection.canada.ca/food-labels/labelling/industry/nutrition-labelling/elements-within-the-nutrition-facts-table/eng/1613599715710/1613599936553#s4c1 https://inspection.canada.ca/food-labels/labelling/industry/... Energy value of dietary fibre A value of 2 Cal (8 kJ) per gram should be used for the dietary fibre portion of the fibre source. A value of less than 2 Cal (8 kJ) per gram may be used for the dietary fibre content if a specific value is available for the fibre source. Energy value of bran The energy value of the fibre portion of wheat bran is 0.6 Cal (2.5 kJ) / g and the wheat bran itself has an energy value of 2.4 Cal (10 kJ) / g.
