Whole grains

Higher whole-grain intake is associated with lower cardiovascular disease, type 2 diabetes and all-cause mortality across large cohorts in many countries, and feeding trials show the expected changes in cholesterol and glycaemic control. Oat beta-glucan's LDL effect is strong enough to carry authorised health claims. The usual caveat applies — whole-grain eaters differ in other ways — but the consistency here is unusual.

How this list was built

We searched Europe PMC for English-language papers published since 2012 whose title contains “whole grain” or “whole-grain”, kept meta-analyses, systematic reviews, trials and observational studies, because a diet or exposure like this cannot be randomised for long and its outcome evidence lives in cohorts, then ranked them by study design first, then recency and citations. Retracted papers are removed.
