(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 risk23 25 or hazard ratio26 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.23 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)
