In Vitro Effects of Aqueous Extracts of Turkish Coffee and Instant Coffee on Glucose Metabolism in Cow Liver Tissue

Coffee consumption has been reported to reduce fasting plasma glucose levels. The aim of this study was to investigate possible effects of aqueous coffee extracts on hepatic glucose metabolism. Cow liver homogenate was used in the assays. After adding glucose, homogenates were incubated with Turkish coffee and instant coffee extracts (5%, 15%, 25% w/v) and then, glucose concentrations were measured within 2 h intervals for 4 hours.
