The problem is bioaccumulation: taking in substances faster than you can metabolize and excrete them. Eating something that has already accumulated something is worse than accumulating it from the same original sources. That’s why you can do suicide by vitamin A poisoning by eating carnivore livers.
It’s also the case that when you’re eating plant-based foods, unlike meat and dairy products, you’re eating alpha- and beta-carotene and beta-cryptoxanthin, which your body can convert to Vitamin A and which don’t cause hypervitaminosis.
So if you’re just learning “Oh, shit, Vitamin A can poison me”, don’t let that hold you back from squash, yams, carrots etc.
Honestly all that toxic shit is in our food already. There’s a reason it accumulated in the “victim” too.
