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

Abstract

Background: UK Government recommendations for dietary fibre intakes have recently increased 5 to 30 g/day, well below current population intakes. This study aimed to explore whether this target 6 could be achieved and the effects on markers of cardiometabolic health. Methods: In this four-week, high fibre intervention study 15 participants were instructed to achieve 8 dietary fibre intakes of 30 g/day. Results: Dietary fibre intakes significantly increased post intervention (16.0 ± 8.1 g/day; p<0.001). 10 No significant changes in glucose and triglyceride concentrations were observed and there was a 11 significant increase in average body weight (0.7 ± 1.2 kg p = 0.025). Conclusion: This study shows 12 that achieving the new dietary fibre recommendations of 30g/day is achievable, in the short-term, in 13 a sample of British adults without any observed effect on health markers.
