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

BACKGROUND: UK Government recommendations for dietary fibre intakes have recently increased to 30 g per day, well below current population intakes.

AIM: This study aimed to explore whether the target for dietary fibre intake could be achieved and the effects on markers of cardiometabolic health.

METHODS: In this 4-week high-fibre intervention study, 15 participants were instructed to achieve dietary fibre intakes of 30 g/day.

RESULTS: 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).

CONCLUSIONS: 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.
