Is sugar free sodas dangerous?
No, there is no research that shows that sweeteners such as aspartame and sucralose are dangerous. However, we prefer to compare sugary soft drinks against light soft drinks and the effects on health. It is beyond reasonable doubt that soft drinks with sugar are among the worst there is. Some people like to compare soft drinks with water and that you should drink water. That's right, but we do not choose to drink soft drinks because we prefer water.

It has even been shown in a study that it has a better or equivalent effect on blood sugar, insulin sensitivity and weight.
