Can healthy motivated British adults achieve the revised UK government fibre recommendations of 30 g per day? Results from a preliminary study

UK Government recommendations for dietary fibre intakes have recently increased to 30 g per day, well below current population intakes. This study aimed to explore whether the target for dietary fibre intake could be achieved and the effects on markers of cardiometabolic health. In this 4-week high-fibre intervention study, 15 participants were instructed to achieve dietary fibre intakes of 30 g/day. Dietary fibre intakes significantly increased post intervention (16.0 ± 8.1 g/day, p < 0.001). No significant changes in glucose and triglyceride concentrations were observed and there was a significant increase in average body weight (0.7 ± 1.2 kg, p = 0.025). This study shows that achieving the new dietary fibre recommendations of 30g/day is achievable, in the short term, in a sample of British adults without any observed effect on health markers
