Brief Summary:
There is an urgent need for stronger evidence to support recommendations for the role of sugars in diabetes and related cardiometabolic diseases. Although large prospective cohort studies have shown a significant positive association of fructose-containing sugars-sweetened beverages with incident obesity, diabetes, heart disease, and stroke, these associations do not appear to hold true for total fructose-containing sugars and other important sources of free fructose-containing sugars such as pure fruit juice, yogurt, or even cakes and sweets. As dietary guidelines have moved away from macronutrient centric recommendations towards more food and dietary-pattern based recommendations, this inconsistency in the data has not been appreciated. There remains a focus on free sugars, in the absence of sufficient information on the role of different food sources of fructose-containing sugars in diabetes and related cardiometabolic diseases. A systematic review and meta-analysis of prospective cohort studies is considered to be the "Gold Standard" of evidence. To provide evidence-based guidance to support the development of public health policy in relation sugars and the primary prevention of diabetes, we will conduct a series of systematic reviews and meta-analyses of the relation of food sources of fructose-containing sugars with incident type 2 diabetes and related cardiometabolic diseases in prospective cohort studies.
