I believe that technically, veggies grow on the plant, and fruits hang from the plant. Hence, a tomato is technically a fruit...
But that has been such a long and holy war that I won't get into it
And potatoes are actually pretty good, unless they've been fried in beef fat and turned into french fries. That extra oil knocks down a bit of the healthy stuff.
The kid's parents made a choice. Apparently, they made a bad (and costly, when you think about eating at McD's for eleven years) choice. We go out to eat with the kids at least once a week (the Friday night family dinner). Sometimes, the kids pick, and McD's is an option. They get what they want (within reason), they eat what they want, and then they play in the play area (getting some of that physical exercise). No problems so far, and none foreseen.
Are we eating there BLD? Not hardly.
I guess moderation is the key... and I wonder what stellar specimens of perfect health the kid's parents are...
