Glucose is an essential source of energy in humans.Over the past decades,consumption of sugar has increased greatly and constitutes a large part of the global energy intake[1].Currently,overconsumption of sugar is a serious problem around the world and contributes to the high incidence of obesity,type 2 diabetes mellitus,hyperten-sion,and all-cause mortality[1].As a result,there is an unmet clinical need to clarify the mechanisms of sugar preference and craving and to find means of limiting sugar overconsumption.
