Greater intake of dietary fiber can substantially reduce the risk of coronary heart disease, particularly coronary death, in middle-aged, smoking men.
Practitioners should encourage increased dietary fiber intake to lower coronary heart disease risk in this demographic.
StrongSupportsmedium confidence
These findings suggest that independent of other risk factors, greater intake of foods rich in fiber can substantially reduce the risk of coronary heart disease, and particularly coronary death, in middle-aged, smoking men.
Why this rating
Based on a large randomized, double-blind, placebo-controlled trial.
