If you dislike the bitter aftertaste of artificial sweeteners and you’re looking for a good reason to switch back to real sugar, this may be it.

Researchers at the Federal University of Rio Grande do Sul, Brazil,  fed rats yogurt sweetened with either sugar, aspartame or saccharin, plus unlimited food and water. At the same time, they restricted their physical activity. They measured the rats’ total caloric intake and weight gained every week for 12 weeks.

At the end of the study, those rats who had eaten the artificially sweetened yogurt had gained more weight than those eating the yogurt sweetened with sugar, despite the fact that the caloric intake was the same. The scientists speculate that the rats who gained additional weight may have had reduced physical activity or increased fluid retention.

The study, reported in Appetite last week, will support campaigners for real food in our diets.
