Something convinced people that sugary cereals aren't just something you can use to survive in a pinch, but actually contain acceptable nutrition. People think Special K is healthy. Or Slimfast advertising 10g protein (with milk teehee) when it's actually got 2 g protein and 11 g sugar. People think this is "diet" food. Chocolate milk powder. They really buy it. How sheltered are you? And then it causes real harm to people when they think "dieting" just doesn't work for some people.

This isn't just "lol dumb people got tricked". It's fraud. Plenty of apparently reasonable people take the intended (false) meanings from advertisements. These are intentional misrepresentations. And it's not one or two egregious actors. The entire industry is about deceiving to the maximum extent allowed by law, which is a lot.

Like I said the (colloquial) idea of a food desert is plausible, but there is no information on it. The stats are not looking at how many people have a highway blocking the way and you have to go uphill both ways in a wheelchair after working 3 jobs, so actually that 0.5 miles is burdensome. They tell us nothing (well, they tell us how many people don't even have to walk 10 minutes to reach a fully stocked supermarket). If you think that's the scenario being discussed when people talk about food deserts, it's coming from your imagination. Maybe it exists. It's not what the term means. It's almost like the term was chosen to be evocative and paint a certain picture of reality.
