In the course of his research assistants checked as one of the relatively new types of sweeteners affect the brain, digestion, and behavior of fruit flies (Drosophila) and mice. As a result, the attention of scientists was attracted by the work of brain structures, designed to assess the nutritional value of food. As it turned out, the animals, the diet of which a sweetener was included, was inclined to underestimate the energy value of their food, and, as a consequence, quickly started to feel the hunger. As a result, after five days of diet, including artificial sweeteners, fruit flies began to consume almost a third more calories than those that were included in the control group. Similar results were obtained in experiments with mice that, according to scientists, with a high probability says about the applicability of the findings to all mammals, including humans.

According to experts, they also found that consuming artificial sweeteners often provoked signs of hyperactivity, insomnia and reduced quality of sleep — all this is often a consequence of feelings of hunger. As scholars have noted previously in some studies such effects of sugar substitutes were documented, including in humans, however, the new job, according to its authors, allows to understand better the nature of such dependence.

Summing up his research, biologists emphasize that today the sweeteners in food uses a huge number of people despite the fact that the impact of these sweeteners on the body is not studied to the full, and new data show that clearly positive it is not.

The results of their study, the researchers shared in the journal Cell Metabolism.
