I live in central Europe and veggies and fruit are one of the first things, you see when you enter a store. They’re also really affordable and you can get them in pretty much every corner store all over the town as well. There isn’t a place where basic fruit and veggies are more than 15 minutes walking/public transit distance from you within the city. Never had to drive to a grocery store in my life. Some places are even open at night.
Let’s not blame the people for eating like this, when that’s exactly what the system is set up for.
