It belongs to the group of compounds. known as methylxanthines which include. theobromine (cocoa) and theophylline (tea). Because of its excellent solubility and slow rate. of degradation, caffeine can persist in aquatic. environments (Seiler et al., 2005) and has the. potential to biomagnify through the food chain. Thus, even a small amount of dissolved caffeine. in aquatic environment can concentrate over. time.
Coffee has been associated with a reduced risk of developing diabetes. Caffeinated and decaffeinated coffee may have components other than caffeine that reduce blood glucose concentrations. But take the caffeine out of the coffee, and the caffeine will increase blood sugar up to 8% according to a recent study.
