How strong is the evidence for Vegetables?

A large meta-analysis of prospective cohorts, together with a dose-response meta-analysis linking fruit and vegetable intake to lower cardiovascular disease, cancer, and all-cause mortality, provides consistent support for a cardiometabolic benefit of higher vegetable intake. That evidence is currently rated strong (72/100), built on 6 published studies, including 2 meta-analyses -- enough for real confidence in the effect.
