Looking for health and wellness books that aren’t written by people who think ALL illness can be treated naturally?

I absolutely believe that there are certain powerful foods and wellness activities that can lead to longer, healthier lives and I’d like to find books that talk about this and discuss chronic pain and what we can eat and do to limit this. But the books I’m coming across are also written by Covid-deniers or people who think natural remedies cure cancer, etc. and that’s when I begin to think their books are scams. I’m looking for books that encourage natural remedies but aren’t written by people who think it’s an end-all, be-all if that makes sense? They can still acknowledge the importance of the medical community without relying on it. Thanks!
