"in which countries switch away from simple, whole-food diets as they become wealthier" Is this actually the case? I see the switch away happening when whole-food diets become more expensive. The whole point of processed foods is that they can be made, delivered and served at industrial scale, cheaply. Cooking at home isn't even cheaper to many people because the required time shopping and preparing is expensive. This isn't because the countries are wealthier, but due to income disparity. The wealthy can afford the expensive, healthier choices. Interesting where Australia sits. Maybe the tyranny of distance? Without the population to sustain too much of a local manufacturing industry, most of the ULP food is imported, raising the costs.
