Since I reached the "can afford to shop at whole foods if I wanted to" stage of my life, the combination of lifestyle, genetics, and diet means I'm pretty far from diabetes at the moment.

But when I was a lot worse off, I bought the food I could afford, which tended to be the low-cost, high-calorie stuff that leads to health problems. Maybe (and I'm just spitballing here) we should find a way to lower the cost of higher-quality food. The decision for huge swaths of the world should not be "afford enough food to not starve, but the food is of such low quality that it leads to long-term health problems" vs "starve while eating food that, if eaten in sufficient quantity, would not lead to long-term health problems". Optimizing for dollars per calorie means you end up picking high carb options.

Telling people in Somalia or wherever "have you just tried keto?" is a pretty problematic stance.
