You’re probably just helping poor people acquire diabetes faster. In the USA poor people are more likely to be fat suggesting food access is not a problem.
People associate fast food and lower quality food with type 2 diabetes, but Type 2 is associated with excessive carb intake. More expensive food often has just as many carbohydrates.
Perhaps but it’s really that fat people eat too much. If you’re going to eat a rich meal then limit the amount you eat. Don’t drink soda all day. Avoid snacking all day.
It’s really an issue with personal responsibility more than food choice.
