Scientists test artificial sweeteners on animals using way more than humans would ever eat, then say it’s safe for people by dividing that huge dose by 100—but that doesn’t match how much people actually consume.

This study gave animals a lot more artificial sweetener than people usually eat, then used that to guess what might happen to humans — which is exactly what the claim says happens.

This study looked at how animals reacted to artificial sweeteners at high doses — much higher than what people usually eat — and found possible health effects. This matches the claim that animal studies use crazy-high doses that don’t reflect real human habits.

Scientists gave rats a lot of sucralose—way more than humans ever eat—and found the sweetener stuck in their fat and changed in ways no one knew about. This supports the idea that animal studies use crazy-high doses that don’t match how much people actually consume.

This study says that even the amount of artificial sweetener deemed 'safe' for humans might still harm the brain, especially in kids or people with health problems — which means the safety rules might be too loose, just like the claim says.
