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 .
Brain functional magnetic resonance imaging response to glucose and fructose infusions in humans.
AIMS In animals , intracerebroventricular glucose and fructose have opposing effects on appetite and weight regulation . In humans , functional brain magnetic resonance imaging ( fMRI ) studies during glucose ingestion or infusion have demonstrated suppression of hypothalamic signalling , but no studies have compared the effects of glucose and fructose . We therefore sought to determine if the brain response differed to glucose vs. fructose in humans independently of the ingestive process . METHODS Nine healthy , normal weight subjects underwent blood oxygenation level dependent ( BOLD ) fMRI measurements during either intravenous ( IV ) glucose ( 0.3 mg/kg ) , fructose ( 0.3 mg/kg ) or saline , administered over 2 min in a r and omized , double-blind , crossover study . Blood was sample d every 5 min during a baseline period and following infusion for 60 min in total for glucose , fructose , lactate and insulin levels . RESULTS No significant brain BOLD signal changes were detected in response to IV saline .  BOLD signal in the cortical control areas increased during glucose infusion ( p = 0.002 ) , corresponding with increased plasma glucose and insulin levels . In contrast , BOLD signal decreased in the cortical control areas during fructose infusion ( p = 0.006 ) , corresponding with increases of plasma fructose and lactate . Neither glucose nor fructose infusions significantly altered BOLD signal in the hypothalamus . CONCLUSION In normal weight humans , cortical responses as assessed by BOLD fMRI to infused glucose are opposite to those of fructose . Differential brain responses to these sugars and their metabolites may provide insight into the neurologic basis for dysregulation of food intake during high dietary fructose intake
