You know when a food additive is bad when they start removing it voluntarily. A lot of sodas switched to sucralose years ago. Companies don't completely change their formula for fun. And I don't think consumer pressure drove them to do it either. At some point they found out that the shit was bad and they could be sued if they kept using it. So they got ahead of it. They don't want to be tobacco'd.
Same thing with all the uncured luncheon meat that started years go. All those extra curing additives causes cancer too.
Sucralose will probably have its day too. I noticed a huge spike in stevia and monk fruit being pushed ahead of sucralose. And splenda dove deep into those alternate sweetners. They could probably drop sucralose and be fine.
