No, there is no evidence of artificial sweeteners causing harm. There is no conspiracy, and after many many studies over decades, nothing has been found. If there had been, then the artificial sweeteners would have been banned like the ones you’ve never heard of because we all banned them for causing problems.
If you drink regular soda today, you should absolutely look at replacing that with a diet varient without sugar. From everything we have learned over decades, it’s absolutely safe.
