In healthy subjects , appetite and short term food intake , risk of cancer , risk of diabetes , risk of dental caries , weight gain and risk of obesity are the most investigated health outcomes .
Overall there is no conclusive evidence for beneficial and harmful effects on those outcomes .
In subjects with diabetes and hypertension , the evidence regarding health outcomes of NNS use is also inconsistent .
Background Food products containing non-nutritive sweeteners ( NNSs ) instead of sugar have become increasingly popular in the last decades .
Their appeal is obviously related to their calorie-free sweet taste .
However , with the dramatic increase in their consumption , it is reasonable and timely to evaluate their potential health benefits and , more importantly , potential adverse effects .
The main aim of this scoping review was to map the evidence about health outcomes possibly associated with regular NNS consumption by examining the extent , range , and nature of research activity in this area .
The effect of non-caloric sweeteners on cognition, choice, and post-consumption satisfaction
Consumers often turn to non-caloric sweeteners ( NCS ) as a means of promoting a healthy body weight . However , several studies have now linked their long-term use to increased weight gain , raising the question of whether these products produce unintended psychological , physiological , or behavioral changes that have implication s for weight management goals . In the following , we present the results of three experiments bearing on this issue , testing whether NCS-consumption influences how  individuals think about and respond to food .  Participants in each of our three experiments were r and omly assigned to consume a sugar-sweetened beverage , an unsweetened beverage , or a beverage sweetened with NCS . We then measured their cognition ( Experiment 1 ) , product choice ( Experiment 2 ) , and subjective responses to a sugar-sweetened food ( Experiment 3 ) . Results revealed that consuming NCS-sweetened beverages influences psychological processes in ways that - over time - may increase calorie intake
