Food Deserts are defined in a way that is unhelpful, I live in a food desert in one of the richest counties. I have 0 grocery stores within 1 mile. But I have 6 grocery stores within 3 miles.
Go ahead with the conventional sayings: Tell me the fallacious remark about McDoubles being the healthiest cheapest food ever. Go ahead and say something incorrect like processed foods are cheaper than fresh foods. In a few years you are going to change from thinking Fat is the devil to carbs are the devil. Then you will take up fasting, then keto, then gluten free.
People in the US have too much money to care about food. These are people getting dopamine from food pleasure. No one wants to admit it.
