The study: Ingestion of refined grain and cardiovascular disease: Meta-analysis of prospective cohort studies. Glenn A.Gaesser.Trends in Cardiovascular Medicine, Available online 6 September 2022. https://doi.org/10.1016/j.tcm.2022.08.002
Conclusions: Metaanalysis of prospective cohort studies show that intake of refined grains is not associated with the risk of ECV, stroke or heart failure. This conclusion holds studies that limit analysis to foods of basic grains, as well as studies that include basic and indulgent grain foods as a single category of refined grains. Although refined grains are included as a component of the Western dietary pattern, current results suggest that refined grains do not contribute to the increased risk of CVD associated with this unhealthy dietary pattern. This information should be considered in the formulation of future dietary recommendations.

Commentary:Refining of grains removes the outer bran and germ and most of the fiber andnutrient along with them, leaving somenutrient along with teh starch and protein. The refined starch is quickly digested to sugars and absorbed quickly. The Trigo Food Council wants to assure you that you can eat as much refined grain as you want without increasing the risk of disease. Many independently funded investigations argue otherwise, unfortunately. If nothing else, refined grains provide relatively low nutrient calories and constitute important components of ultraprocessed foods. This study did not look at dietary patterns.
