The lithium hypothesis doesn't really much scrutiny. I mean they include Canada, but exclude Norway because it's not a warm arid climate? Also how do they explain obesity in New Zealand (a country that they conveniently forgot when talking about high obesity countries), which had a single refinery which closed 2 years ago. Also if proximity to oil production would be a reason, maybe don't treat a place like Australia as a single entity. The oil producing places are largely (with the exception of Gipps basin) quite far away from where people live. If that is still close enough, than all of Europe should be affected by e.g. Norwegian oil production.
