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 .
Dietary sugars stimulate fatty acid synthesis in adults.
The goal of this study was to determine the magnitude by which acute consumption of fructose in a morning bolus would stimulate lipogenesis ( measured by infusion of 13C1-acetate and analysis by GC-MS ) immediately and after a subsequent meal . Six healthy subjects [ 4 men and 2 women ; aged ( mean + /- SD ) 28 + /- 8 y ; BMI , 24.3 + /- 2.8 kg/m(2 ) ; and serum triacylglycerols ( TG ) , 1.03 + /- 0.32 mmol/L ] consumed carbohydrate boluses of sugars  ( 85 g each ) in a r and om and blinded order , followed by a st and ardized lunch 4 h later . Subjects completed a control test of glucose ( 100:0 ) and a mixture of 50:50 glucose : fructose and one of 25:75 ( wt : wt ) . Following the morning boluses , serum glucose and insulin after 100:0 were greater than both other treatments ( P < 0.05 ) and this pattern occurred again after lunch . In the morning , fractional lipogenesis was stimulated when subjects ingested fructose and peaked at 15.9 + /- 5.4 % after the 50:50 treatment and at 16.9 + /- 5.2 % after the 25:75 treatment , values that were greater than after the 100:0 treatment ( 7.8 + /- 5.7 % ; P < 0.02 ) . When fructose was consumed , absolute lipogenesis was 2-fold greater than when it was absent ( 100:0 ) . Postlunch , serum TG were 11 - 29 % greater than 100:0 and TG-rich lipoprotein-TG concentrations were 76 - 200 % greater after 50:50 and 25:75 were consumed ( P < 0.05 ) . The data demonstrate that an early stimulation of lipogenesis after fructose , consumed in a mixture of sugars , augments subsequent postpr and ial lipemia . The postlunch blood TG elevation was only partially due to carry-over from the morning . Acute intake of fructose stimulates lipogenesis and may create a metabolic milieu that enhances subsequent esterification of fatty acids flowing to the liver to elevate TG synthesis postpr and ially
