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 .
Safety of long-term large doses of aspartame.
Safety of long-term administration of 75 mg/kg of aspartame per day was evaluated with the use of a r and omized , double-blind , placebo-controlled , parallel-group design in 108 male and female volunteers aged 18 to 62 years . Subjects received either aspartame or placebo in capsule form three times daily for 24 weeks . No persistent changes over time were noted in either group in vital signs ; body weight ; results of st and ard laboratory tests ; fasting blood levels of aspartame 's constituent amino acids ( aspartic acid and phenylalanine ) , other amino acids , and methanol ; or blood formate levels and 24-hour urinary excretion of formate . There also were no statistically significant differences between groups in the number of subjects experiencing symptoms or in the number of symptoms per subject . These results further document the safety of the long-term consumption of aspartame at doses equivalent to the amount of aspartame in approximately 10 L of beverage per day
