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 .
Tea-induced calmness: Sugar-sweetened tea calms consumers exposed to acute stressor
The food and beverage industry has been increasingly replacing sugar with non-nutritive sweeteners in their sweetened products to control or reduce total calories . Research comparing the effect of nutritive and non-nutritive sweeteners on emotional state of participants exposed to acute stressors is still limited . This study aim ed to determine the effect of drinking tea sweetened with either a nutritive sweetener ( sugar ) or a non-nutritive sweetener ( sucralose or stevia ) on emotional state , in terms of calmness and pleasantness , of participants exposed to an acute stressor . Effects of acute stress on sweetness intensity and overall liking of tea beverages were also determined . Results showed that the possibility of tea-induced calmness , calculated as the difference between calmness ratings after and before drinking a tea sample , was established on stress session in the sugar-sweetened tea .  Overall liking , but not the sweetness intensity , of the sugar-sweetened tea was affected by acute stress . In conclusion , this study provides empirical evidence that the consumption of tea sweetened with nutritive sweetener , but not with non-nutritive sweetener , has calming effect on consumers with acute stress , suggesting that this effect may not be due to the sweet taste of sugar , but due to the caloric nature of the sweetener
