In 1991, the Committee on Medical Aspects of Foods (COMA) defined dietary fibre as non-starch polysaccharides (NSP) and set the DRV as the population average intake of 18 g/day 1 , determined using the Englyst method of analysis 2 . The latest publication of the Scientific Advisory Committee on Nutrition (SACN) 3 broadened the definition of dietary fibre beyond NSP to broader definition of Association of Analytical Communities (AOAC) fibre, recommending the DRV to be 30 g/day based on AOAC method. The COMA 1991, DRV of 18 g/day of NSP corresponds to around 24 g/day of AOAC fibre 3 and therefore the new DRV of fibre would represent a higher recommendation (around 22·5 g fibre as per the Englyst method) for the average population. The purpose of this study was to investigate variation in fibre intake of English population by age and gender, in comparison with the COMA and SACN DRVs. Data on the core sample of the National Diet and Nutrition Survey rolling programme from 2008–2012 was reanalysed. Children aged below 16 years were excluded in consideration of their different DRVs. The data on dietary fibre was extracted from fully productive individuals (i.e. participants who completed three/four diary days), as an average daily intake based on the NSP/Englyst fibre. Inferential statistics included the analysis of variance to discover if there were any significant variations in fibre intake of males and females in relation to their age groups. The statistical significance was set at 0·05. For all age groups, the average fibre intake is below the DRVs. The average daily fibre intake slightly increased with age for both genders until 64 years. When differences in energy intake were taken into account, the average daily fibre density (g/1000 kcal) still increased with the age of participants. Overall, less than a third of populations had an intake above the COMA DRV 1 . More than 90 % of the population had intake below the SACN DRV 3 , demonstrating a challenge for future policies to meet the nutritional guidelines, particularly amongst females and younger adults. The findings should be treated with caution considering the definition of AOAC fibre used as the basis for the SACN DRV includes non-digestible oligosaccharides, resistant starch and polydextrose, going beyond NSP/Englyst variables analysed.Citation
