Of all the exceptional changes on the dietary guidelines, such as the inclusion of ketogenic diets for metabolically ill patients which is most Americans, they unfortunately missed the glaring defect in the recommended limit of 10% or less total calories from saturated fat. Of all the things in the old guidelines, this had the most robust, high level clinical evidence supporting its change.
In this video I discuss and umbrella review, which is a meta-analysis of meta analyses of randomized controlled trials, published in the top cardiology journal in the world, the Journal of the American College of Cardiology, in 2020 showing that saturated fat unequivocally does not cause heart disease, protects against strokes, and that there should be NO limitations on the amount of saturated fat that is recommended safe to eat.
Direct from the authors: âThe recommendation to limit dietary saturated fatty acid (SFA) intake has persisted despite mounting evidence to the contrary,â and recent meta-analyses show no benefit to cutting saturated fat for heart disease or mortality, with a protective signal for stroke.
This is not coming from fringe voices but from an international team of leading cardiology and nutrition scientists, including former chairs and members of the official U.S. Dietary Guidelines Advisory Committees that originally wrote the lowâsaturated-fat advice. Among the authors are Prof. Arne Astrup (University of Copenhagen, obesity and nutrition), Dr. Janet C. King (PhD, RD, chair of the 2005 U.S. Dietary Guidelines Advisory Committee), and Dr. JosĂ© M. OrdovĂĄs (Tufts/USDA HNRCA, a global leader in nutrigenomics and a member of the 2015 Dietary Guidelines Advisory Committee).
In other words, the very experts who helped shape the original âlimit saturated fatâ policy are now publishing in the Journal of the American College of Cardiology that blanket caps on saturated fat are not supported by the best current evidence and should be replaced by foodâbased, individualized recommendations.
