Mixed

Specific types of fibre (soluble, insoluble, cereal, vegetable) show varying degrees of association with reduced cardiovascular risk, with insoluble and cereal fibre showing significant risk reductions.

Not all fibre sources are equal in this analysis. Insoluble fibre (found in whole grains, nuts, seeds) and fibre from cereals and vegetables showed stronger associations with risk reduction than fruit fibre alone. Prioritize whole grains and vegetables for maximum cardiovascular benefit.

GoodSupportsHIGH confidence
lower risk of cardiovascular disease and coronary heart disease was associated with greater intake of total fibre, insoluble fibre, and fibre from cereals and vegetables.

Why this rating

Based on the same high-quality meta-analysis, but subgroup analyses can be less robust than primary outcomes.
