حمض الأورسوليك قد يساعد في دراسة صحة الكوليسترول في الأمعاء

A study in hamsters found that ursolic acid, a compound in apples, blueberries, and cranberries, reduced plasma cholesterol by 15-16% and inhibited intestinal cholesterol absorption by 2.6-9.2%. It also improved gut microbiota by lowering the Firmicutes to Bacteroidetes ratio and promoting short-chain fatty acid-producing bacteria, though human trials are needed.
