Abstract

<p>This study sought to determine the possible detrimental effects of several low- or non-caloric sweeteners on endothelial progenitor cells (EPCs), inflammation and behavioural changes in mice. C57BL/6 male mice received low and high dose of natural and artificial sweeteners for 4 weeks. EPCs, physical and biochemical variables, inflammation and behavioural changes were evaluated. A significant reduction of about 25% of EPCs was found when mice received a moderate amount of all sweeteners (<i>p</i> < .05). This reduction was more strongly significant when a double dose of glucose, aspartame, rebaudioside A and cyclamate (<i>p</i> < .005) in comparison to fructose and sucrose (<i>p</i> < .05) was administered. During inflammation carrageenan-induced, all sweeteners produced a significant increase of EPCs compared to the control group (<i>p</i> < .05). Consumption of glucose and sugar substitutes affect mouse EPC number according to the absence or presence of an inflammatory status, but does not induce detrimental effects on inflammation and behavioural changes.</p
