Two-Day Oat Diet Lowers LDL Cholesterol, Possibly via Gut Bacteria
In a small study of adults with metabolic syndrome, participants ate 100 g of rolled oats three times daily for 48 hours and saw total cholesterol fall about 8% and LDL drop around 10%, with these effects persisting six weeks after returning to their usual diet. Researchers suggest the changes may stem from gut bacteria metabolizing oats into compounds like ferulic acid that improve cholesterol metabolism. A longer six-week oats-only trial produced smaller, slower benefits. Larger studies are needed to confirm the findings.
