Researchers have discovered new compounds in roasted coffee that may help control blood sugar levels. These compounds inhibit α-glucosidase, an enzyme associated with type 2 diabetes. Some of the discovered molecules were more effective than commonly used antidiabetic drugs in laboratory tests. The study also presented a new, faster and more environmentally friendly way to identify health-promoting compounds in complex foods like coffee. The findings suggest that roasted coffee could have potential beyond its usual stimulant effect. The research was conducted under laboratory conditions, which means that further clinical studies would be necessary to confirm the effectiveness in humans.
