Brief Summary
Sugars have been implicated in the epidemics of overweight and obesity. This view is supported by lower quality evidence from ecological observations, animal models, and select human trials. Higher level evidence from controlled trials and prospective cohort studies has been inconclusive. Whether sugars contribute to weight gain or increases in adiposity independent of their calories and whether important food sources of sugars other than SSBs are associated with a higher risk of overweight and obesity or weight gain remain unclear. To address the uncertainties, the investigators propose to conduct a series of systematic reviews and meta-analyses of the totality of the evidence from controlled trials and prospective cohort studies to distinguish the contribution of fructose-containing sugars and important food sources of sugars (SSBs, fruit, 100% fruit juice, cakes/sweets, yogurt, cereals, etc) from that of energy in the development of overweight and obesity. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing evidence-based guidelines and improving health outcomes by educating healthcare providers and patients, stimulating industry innovation, and guiding future research design

Interventions
An intervention in which calories from food sources of fructose-containing sugars are substituted, added, subtracted, or replaced ad libitum in the diet
Eligibility Criteria
All individuals, both children and adults, regardless of health status.
You may qualify if:
- Randomized and non-randomized controlled intervention studies in humans
- Oral fructose-containing sugars intervention
- Presence of a reduced fructose-containing sugars comparator in one of 4 energy controlled designs (substitution, addition, subtraction, or ad libitum)
- Diet duration \>=2 weeks
- Viable outcome data
- Prospective cohort studies
- Duration \>= 1 year
- Assessment of the exposure of food sources of fructose-containing sugars
- Ascertainment of viable outcome data by level of exposure
You may not qualify if:
- Observational studies or intervention studies with no control group
- IV or parenteral fructose-containing sugars intervention
- Lack of an adequate comparator (i.e. lack of a difference (\<5 g) in fructose-containing sugars between the intervention and control diets)
- Ecological, cross-sectional, or retrospective observational studies
- Intervention studies
