High intensity-sweeteners (HIS) are natural or synthetic substances, sweeter than sugar, providing sweetness without calories. Sweeteners are mainly used as an aid in losing Weight, preventing obesity and controlling blood sugar levels for diabetics. The objective of this study was to evaluate the carcinogenic potential of the sweeteners aspartame, sucralose, sodium saccharin and steviol glycoside, using the test for detection of epithelial tumor clones in Drosophila melanogaster. Larvae of 72 +/- 4h, obtained from wts/TM3 female mated with mwh/mwh males, were treated for approximately 48h with different concentrations of aspartame (0.85, 1.7, 3.4, 6.8 or 13.6 mM); sucralose (0.5, 1.25, 2.5, 5.0 or 10 mM); sodium saccharin (25; 50; 100; 200 or 400 mM) and steviol glycoside (2.5; 5.0; 10; 20 or 40 mM). Water (Reverse Osmosis) and doxorubicin (DXR 0.4 mM) were used as negative and positive controls, respectively. No statistically significant differences were observed (p > 0.05) in tumor frequencies in individuals treated with all concentrations of these sweeteners when compared to negative control. It was therefore concluded that, in these experimental conditions, aspartame, sucralose, sodium saccharin and steviol glycoside have no carcinogenic effect in D. melanogaster.
