  1. Mean (±SD) and median NSP fibre content of foods are calculated from all foods recorded in the survey-year. Changes in the distribution of fibre content were tested using Mann–Whitney U-test on all foods reported in each survey year. Paired Wilcoxon-rank sum test was used for food items recorded in the survey both years. Bold values show a significant test at 5%.
