re: New OECD study shows that Obesity is based on culture, not affordability of food

You could put a grocery store in a food desert and its survivability would be on sugary and unhealthy foods. Not because the poor can't afford bananas, lettuce, and tomatoes. Most of them are impulsive and low IQ which makes them choose instant gratification rather than long term benefit. Bad and impulsive decisions along with laziness are what keep them mired in poverty.
