Scientists at the Functional Food Centre at Oxford Brookes University in England fed 8 healthy human subjects ''chapatis'' (unleavened Indian flatbreads) made with 0 g, 2g, 4g, 6g or 8g of barley beta-glucan fiber. They found that all amounts of barley beta-glucan lowered the glycemic index of the breads, with 4g or more making a significant difference7. | Scientists at the Functional Food Centre at Oxford Brookes University in England fed 8 healthy human subjects ''chapatis'' (unleavened Indian flatbreads) made with 0 g, 2g, 4g, 6g or 8g of barley beta-glucan fiber.
