Oats for two days cut LDL cholesterol in Bonn study

In a University of Bonn study, 32 adults with metabolic syndrome followed a calorie-restricted, oat-heavy breakfast for two days. LDL cholesterol fell about 10% within 48 hours, participants lost about 2 kg (4.5 lb), and blood pressure dipped slightly; the cholesterol reduction persisted for six weeks after returning to their usual Western diet, likely via gut bacteria metabolizing oats and producing metabolites that help cholesterol metabolism.
