I would describe many Americans as having an ad libitum diet. I agree with your rationale about drawing conclusions, there are always plenty of factors. In this case we have no reason to expect different housing practices for each population, so it’s reasonable to minimize that as a cause for observed differences. The study suggests this is a potential phenomenon that could apply to humans, but invites further investigations based on objective scientific observation.
