"In vitro testing showed that the three compounds were more effective than a prescription glucose inhibitor used to treat type 2 diabetes by slowing down carbohydrate digestion to prevent blood sugar spikes. To be clear, this was not a human study. Thus, the practical effect these new coffee compounds may have on the body remains unknown, according to the authors."
"The work, led by scientists at the Kunming Institute of Botany within the Chinese Academy of Sciences, is less about telling people to drink more coffee and more about giving food chemists a faster way to hunt for potentially useful bioactive compounds hiding in complex foods like roasted coffee."
"Functional foods offer more than basic nutrition. Many contain naturally occurring molecules that may support health, including compounds with antioxidant, neuroprotective or glucose-lowering effects."
Scientists at the Kunming Institute of Botany discovered six previously unknown compounds in roasted arabica coffee beans. Three of these compounds, named caffaldehydes A-C, are diterpene esters that demonstrated superior effectiveness compared to prescription glucose inhibitors in laboratory testing. These compounds work by slowing carbohydrate digestion to prevent blood sugar spikes. The research emphasizes developing a faster scientific method for identifying bioactive compounds in complex foods rather than promoting increased coffee consumption. While previous research suggests diterpenes in coffee may support type 2 diabetes prevention, this study was conducted in vitro only, so human health effects remain unknown. The findings suggest potential for developing coffee-based functional foods and nutraceuticals for glucose control.
