Since uncontrolled observational studies first linked fructose to the epidemic of obesity almost a decade ago, it has become a focus of intense concern regarding its role in the obesity epidemic. Despite the uncertainties in the evidence,the recommendations of international health organizations have cautioned against moderate to high intakes fructose-containing sugars, especially those from sugar sweetened beverages (SSBs). To improve the evidence on which nutrition recommendations are based, the investigators propose to study of the effect of fructose-containing sugar sweetened beverages (SSBs)on body weight, by undertaking a systematic synthesis of the data taken from all available clinical studies in humans. This technique has the strength of allowing all of the available data to be pooled together and differences to be explored in groups of different study participants (healthy humans of different sex, weight, and age and in those with diseases which predispose to disturbances in metabolism, such as diabetes) with dietary fructose in different forms, doses, and with differing durations of exposure. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing recommendations for the general public, as well as those at risk of diabetes and cardiovascular disease.
