I understand the parent's worry here. You worry that you're going to give your kid a healthy snake, but at the end of the day they're going to eat something very unhealthy. That's a reasonable worry. Here's the thing though. No kid in their right mind is going to trade a delicious Cheeto for a carrot stick. I'm not knocking carrot sticks. I'll eat a carrot stick with the best of them. Give me some ranch and who knows, maybe I'll eat a whole bag to myself. Against a Cheeto though? Carrot stick is going to lose every time.
I was the kid who had a lunch comprised of a bag of cheetos and a Capri Sun. I was constantly hungry and low energy because of this. I don't blame my parents. I never complained about it. I just lived hungry.
