摘要: Sugars containing fructose are emerging as the dominant public health targets for their role in epidemic of overweight and obesity. This position is largely supported by ecological observations, rodent models overfeeding select human trials. Higher level evidence from systematic reviews meta-analyses controlled dietary trials has yet to show convincingly that fructose-containing sugars behave differently any other forms energy (especially refined starch fat). Prospective cohort studies, which provide strongest observational evidence, have shown an association between risk obesity consumed sugar-sweetened beverages but not total or important sources added such cakes, pastries sweets. Comparative analyses high intakes highly palatable foods grains, processed meats, red French fries potato products, well physical inactivity may play equal greater weight gain The contributions these factors also difficult disentangle owing collinearity with part a Western pattern lifestyle. Attention needs remain focused on decreasing overconsumption all associated Sugar-sweetened certainly place start should draw attention away issue general.
