In beginning of the game, the McDonalds logo only appears on a garbage can and if you run into it - you die. It's a positive message for health conscious parents.
Back in college (now 15 years ago) I did an analysis of fast food menus for a nutrition class.
McDonalds turned out to be the easiest to get a healthy meal from at the time. They had things like salads, apple slices, and a much wider variety of items than other fast food restaurants meaning that if you were to eat there every day it was much easier to make different healthy meals than it was at the others but like an order of magnitude.
Basically just skip the soft drink and only occasionally order the fries and you'll be fine.
The last time I tried McDonalds apple slices they somehow tasted like chemicals. I wonder how much of their "healthy" food is actually healthy. You could recreate a lot of their menu at home using fresh/real ingredients and it'd probably be a lot healthier than the stuff they ship all over the country in plastic, pumped full of salt and preservatives, then wrapped in PFAS.
McDonalds used to be dirt cheap (in the UK), so you could eat there if you didn't have much money. Now it's pretty expensive if I eat there with my kids I could easily spend £20+. It would be way cheaper for me to buy real food and prepare it at home and their price is getting comparable with REAL pub and restaurant food. Given most of their stuff still tastes like cardboard I only go there when my kids need a fix, despite it being walking distance from my home.
