In comparison with the baseline , NNS consumption was not found to increase blood glucose level , and its concentration gradually declined over the course of observation following NNS consumption .
The glycemic impact of NNS consumption did not differ by type of NNS but to some extent varied by participants ’ age , body weight , and diabetic status .
Conclusions NNS consumption was not found to elevate blood glucose level .
Background / objectives Nonnutritive sweeteners ( NNSs ) are zero- or low-calorie alternatives to nutritive sweeteners , such as table sugars .
A systematic review and meta- analysis of r and omized controlled trials was conducted to quantitatively synthesize existing scientific evidence on the glycemic impact of NNSs .
Glucose effects on a continuous performance test of attention in adults
Increases in plasma blood glucose levels modulate memory , mood , and , to some extent , attention in adults . Participants in the present study were administered glucose ( 10 , 100 , and 500 mg/kg , or 50 g ) or placebo ( 23.7 mg saccharin ) shortly prior to completing the test of variables of attention ( TOVA ) , a continuous performance test ( CPT ) commonly used to assess attention for diagnostic purpose s. There were significant increases in blood glucose levels for the 500 mg/kg and 50 g groups , but only the 100 mg/kg group showed significant changes in behavior in comparison to the saccharin group . Specifically , the 100 mg/kg group performed worse on measures of commission errors , post-commission responses , and post-commission response time variability . There were no differences among the groups on other major variables of attention , including omission errors , response time , and response time variability . The results of this study demonstrate that large doses of glucose which increase blood glucose levels do not influence attention , but that a moderate dose ( 100 mg/kg ) selectively impairs measures of impulsivity or disinhibition . Practitioners and research ers should maintain an awareness of dietary effects on attention and continue to examine micronutrients as potential confounds on diagnostic tests of cognition and behavior
