> This is the thing that's tripping up health professionals about gut health, people's guts are really different and there's no official accepted way of testing what kind of diet works for who.
The more I've learned about my personal response to various health interventions, the more I've come to believe that a "human being" as a research subject for many medical interventions is very ill-defined simply because there is too much variation between individuals. The research subject should really be a single human individual. Poorly working medical treatments to many weird, complicated, chronic illnesses should really be replaced by an algorithm that allows a person to find the correct treatment or lifestyle adjustments themselves.
If you haven't read Invisible Women[0] yet, you should. Don't be intimidated by the page count, a good 50% of the book is just listing sources of _everything_.
The tl;dr is that women, for example, have been excluded from all kinds of medical, scientific and safety studies just because it's too hard to include them. Them having periods and hormones and all that stuff that makes science HARD. It's easier just to test on men =)
