Nutrition is important for every meal
No it isn't. 80/20 is a god balance. Lucky you if you've never been in the "shit, what's for dinner, freezer dive" situation. Do you work full time and have to juggle priorities?
That's why we are in an obesity epidemic
No it isn't. We have an obesity epidemic because or a whole load of societal issues, not because occasionally kids eat nuggets.
because people do not understand how important it is.
I think you'll find "people" do. DD eats nuggets occasionally, she's not obese. And not even because she is really active as her disability prevents that. She's on the 25th centile for weight.
I wish more restaurants had vegetables
They do. Every single one I've been at serve meals with veg. I know this because I swap it out for salad. Their veg is mass cooked and has zero nutrition in it.
