A toddler might be able to self regulate real food, but can't self regulate artificial ultra-processed food such as veggie straw which are engineered to be highly palatable. (or rice cakes or cereal bars and other crap)
The Australian consumer magazine had an article about toddler junk food this month and had this to say about the veggie straw which they compared to Cheetos and burger ring"
"" Kiddylicious Veggie Straws, for example – which are essentially puffed-up potato starch, with added veggie powders, salt and oil – have minimal added baddies, it's true. But the point is they're so highly processed they offer little in the way of nutritional value – just empty kilojoules.
They're also reminiscent of mainstream snack products such as Burger Rings and Cheetos, a similar look and feel that isn't ideal if it leads to a taste and preference for those types of snack foods.

Who can stop after 5 Cheetos?
