Data from these sources do not support linkages between sugar consumption at normal levels within the human diet and various adverse metabolic and health-related effects
Abstract The relationship between sugar consumption and various health-related sequelas is controversial .
Some investigators have argued that excessive sugar consumption is associated with increased risk of obesity , coronary heart disease , diabetes ( T2D ) , metabolic syndrome , non-alcoholic fatty liver disease , and stimulation of reward pathways in the brain potentially causing excessive caloric consumption .
These concerns have influenced organizations such as the World Health Organization , the Scientific Advisory Committee on Nutrition in Engl and not to exceed 5 % of total energy and the Dietary Guidelines for Americans Advisory Committee 2015 to recommend upper limits of sugar consumption not to exceed 10 % of calories .
Data from many r and omized control trials ( RCTs ) do not support linkages between sugar consumption at normal levels within the human diet and various adverse metabolic and health-related effects .
Fructose and glucose are typically consumed together in roughly equal proportions from high-fructose corn syrup ( also known as isoglucose in Europe ) or sucrose .
The purpose of this review is to present data from recent RCTs and findings from recent systematic review s and meta-analyses related to sugar consumption and its putative health effects .
This review evaluates findings from recent r and omized controlled trials , systematic review s and meta-analyses into the relationship of sugar consumption and a range of health-related issues including energy-regulating hormones , obesity , cardiovascular disease , diabetes , and accumulation of liver fat and neurologic responses .
Fructose overconsumption causes dyslipidemia and ectopic lipid deposition in healthy subjects with and without a family history of type 2 diabetes.
BACKGROUND Both nutritional and genetic factors are involved in the pathogenesis of nonalcoholic fatty liver disease and insulin resistance . OBJECTIVE The aim was to assess the effects of fructose , a potent stimulator of hepatic de novo lipogenesis , on intrahepatocellular lipids ( IHCLs ) and insulin sensitivity in healthy offspring of patients with type 2 diabetes (OffT2D)--a subgroup of individuals prone to metabolic disorders . DESIGN Sixteen male OffT2D and 8 control subjects were studied in a crossover design after either a 7-d isocaloric diet or a hypercaloric high-fructose diet ( 3.5 g x kg FFM(-1 ) x d(-1 ) , + 35 % energy intake ) . Hepatic and whole-body insulin sensitivity were assessed with a 2-step hyperinsulinemic euglycemic clamp ( 0.3 and 1.0 mU x kg(-1 ) x min(-1 ) ) , together with 6,6-[2H2]glucose . IHCLs and intramyocellular lipids ( IMCLs ) were measured by 1H-magnetic resonance spectroscopy . RESULTS The OffT2D group had significantly ( P < 0.05 ) higher IHCLs ( + 94 % ) , total triacylglycerols ( + 35 % ) , and lower whole-body insulin sensitivity ( -27 % ) than did the control group . The high-fructose diet significantly increased IHCLs ( control : + 76 % ; OffT2D : + 79 % ) , IMCLs ( control : + 47 % ; OffT2D : + 24 % ) , VLDL-triacylglycerols ( control : + 51 % ; OffT2D : + 110 % ) , and fasting hepatic glucose output ( control : + 4 % ; OffT2D : + 5 % ) . Furthermore , the effects of fructose on VLDL-triacylglycerols were higher in the OffT2D group ( group x diet interaction : P < 0.05 ) . CONCLUSIONS A 7-d high-fructose diet increased ectopic lipid deposition in liver and muscle and fasting VLDL-triacylglycerols and decreased hepatic insulin sensitivity . Fructose-induced alterations in VLDL-triacylglycerols appeared to be of greater magnitude in the OffT2D group , which suggests that these individuals may be more prone to developing dyslipidemia when challenged by high fructose intakes .
