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 .
Blood glucose and meal patterns in time-blinded males, after aspartame, carbohydrate, and fat consumption, in relation to sweetness perception.
In a study of the impact of aspartame , fat , and carbohydrate on appetite , we monitored blood glucose continuously for 431 ( SE 16 ) min . Ten healthy males ( 19 - 31 years ) participated in three time-blinded visits . As blood glucose was monitored , appetite ratings were scored at r and omized times . On the first meal initiation , volunteers consumed one of three isovolumetric drinks ( aspartame , 1 MJ simple carbohydrate , and 1 MJ high-fat ; r and omized order ) . High-fat and high-carbohydrate foods were available ad libitum subsequently . Blood glucose patterns following the carbohydrate drink ( + 1.78 ( SE 0.28 ) mmol/l in 38 ( SE 3 ) min ) and high-fat drink ( + 0.83 ( SE 0.28 ) mmol/l in 49 ( SE 6 ) min ) were predictive of the next intermeal interval ( R 0.64 and R 0.97 respectively ) . Aspartame ingestion was followed by blood glucose declines ( 40 % of subjects ) , increases ( 20 % ) , or stability ( 40 % ) . These patterns were related to the volunteers ' perception of sweetness of the drink ( R 0.81 , P = 0.014 ) , and were predictive of subsequent intakes ( R -0.71 , P = 0.048 ) . For all drinks combined , declines in blood glucose and meal initiation were significantly associated ( chi 2 16.8 , P < 0.001 ) , the duration of blood glucose responses and intermeal intervals correlated significantly ( R 0.715 , P = 0.0001 ) , and sweetness perception correlated negatively with hunger suppression ( R -0.471 , P = 0.015 ) . Effects of fat , carbohydrate , and aspartame on meal initiation , meal size , and intermeal interval relate to blood glucose patterns . Varied blood glucose responses after aspartame support the controversy over its effects , and may relate to sweetness perception
