Data concerning effects of aspartame on main metabolic variables associated to diabetes and obesity do not support a beneficial related to its consumption
ABSTRACT Data about harms or benefits associated with the consumption of aspartame , a nonnutritive sweetener worldwide consumed , are still controversial .
This systematic review and meta- analysis of r and omized controlled clinical trials aim ed to assess the effect of aspartame consumption on  metabolic parameters related to diabetes and obesity .
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
