Ah. In this case I meant that this is how I feel about the basis of the idea that it's more healthy (vague, I know) to eat plants than not to. I think that hasn't actually been studied, and people are just using not-exactly-applicable epidemiology combined with speculations.

Maybe you could include ways to see all the diets people have tried and summarize each ones’ health outputs. The controls are all the diets done by people, and the difference they feel is what is measured.

Aside from a number of other issues, asking people to retrospectively analyze their diets and experiences has some massive issues. You'd probably just end up with a tableau of how people feel about each diet, without much information on what the diets actually did
