According to endocrinologist Ekaterina Orlova, beta-glucans slow the absorption of sugars and help stabilize blood glucose levels, which is necessary for preventing metabolic disorders. However, gastroenterologist Sergey Danilov notes that pearl barley should be viewed as part of a balanced diet rather than a standalone therapeutic product.
