The effect of sugar and artificial sweetener on molecular markers of metabolic syndrome: a mice study
Journal Title: Food Research - Year 2017, Vol 1, Issue 6
Abstract
The usage of aspartame, as one of the most widely used sweetener, has been approved in many types of food products. Moreover, many studies have proven that replacing sugar with aspartame would contribute favorable effects on several health parameters; such as, body weight, blood glucose level, and inflammatory status. In this experiment, we examined the effects of aspartame consumption on some biomarkers; which potentially acted as early signals for a personal metabolic status. This study was aimed to investigate the effect of aspartame on the expression of a number of molecular markers related with appetite regulation (fto), fat accumulation markers (fabp4 and alt2) and inflammation marker (tnf-α) in Sprague Dawley rats. The population of Clostridium coccoides was also observed to give an insight about the effect of sweetener consumption on gut microbiota profiles. 15 healthy, male, eight-weeks old Sprague-Dawley rats were fed a standard diet and divided into 3 groups (n=5 for each): water only, sucrose (30% b/v), and aspartame (0.15% b/v). Body weight was measured weekly and blood glucose measurement was carried out on day 1 and 40. At the end of the experiment, all rats were euthanized and blood was collected from the vein. The liver, brain, and visceral adipose tissue were excised, weighed, and grinded with liquid nitrogen. Feces samples were collected on day 0 and 40. At the end of our experimental period; the body weight, liver weight, and blood glucose level of sucrose-treated rats were significantly higher (p <0.05) than aspartame and control group. Sucrose showed the lowest level of fto gene expression; yet, the fto gene expression in aspartame group was still lower than the control group. Expression of several genes considered as metabolic syndrome-related biomarkers were measured (fabp4, alt2, and tnf-α); and our data demonstrated that sucrose treatment gave the highest increase in expression level of those genes; while aspartame treatment showed much lower values. Furthermore, sucrose also caused a significant reduction in C. coccoides population; while, the C. coccoides population in aspartame group did not differ significantly compared to the control group
