Abstract

Nicola M McKeown and colleagues advocate for the importance of translating the health impact of high fibre diets to patients and clients, with emphasis placed on incorporating a variety of plant based foods to achieve dietary fibre recommendations

Conflict of interest statement

Competing interests: We have read and understood BMJ policy on declaration of interests and have the following interests to declare: NMM has received research funding from IFANS for the updating of a publicly available Dietary Fibre Database https://iafns.org/our-work/research-tools-open-data/dietary-fiber-database. NMM has in the past received funding for investigator initiated grants and for payment for serving as a consultant from General Mills Bell Institute of Health and Nutrition, speaker honorarium from Cereal Partners Worldwide, a gift-in kind to support dietary fibre research from P&G, and is an unpaid scientific adviser on the Oldways Whole Grains Council. NMM is currently supported by a grant from the NIH National Heart, Lung, Blood, and sleep disorders. GCF Jr, JS, and JWvdK have no conflict of interests to declare.

Functional properties of dietary fibre. Colours identify dietary fibres that have the same functional properties. Red: soluble, viscous fermentable fibre; green: soluble, viscous, non-fermentable fibre; purple: soluble, non-viscous, fermentable fibre; black: soluble, non-viscous, fermentable fibre; blue: insoluble, partially fermentable; orange: insoluble, non-fermentable

(a) Pooled relative risk estimates from meta-analysis of prospective cohort studies examining associations between dietary fibre and chronic disease risk. Mean follow-up time ranged from 9.2 years for coronary heart disease to 10.9 years for colon cancer and a median follow-up of 12 years for stroke. (b) Pooled relative risk or hazard ratio estimates from meta-analysis of prospective cohort studies examining the association between dietary fibre intake and mortality. Mean follow-up time ranged from 11.5 years for coronary heart disease to 13.2 years for cancer. (c) Pooled relative risks are from meta-analyses examining associations between fibre food sources and type 2 diabetes. Blue dots indicate the estimated risk derived from comparing the high to the low categories of dietary intake (n=10, prospective cohort), and the orange dots indicate the estimated risk derived from a dose-response analysis for 5 g cereal or 2 g fruit or vegetable (n=8, prospective cohort)
