For me for example its “Eat me - a natural and unnatural history of cannibalism” by Bill Schutt. Its an amazing book that covers cannibalism in animals and then the history of it in humans (cultural, survival & medicinal cannibalism).
I got a lot of “oh why would someone read something like that?” And “that not something fun to read about!” From relatives but my friends enjoyed the stuff that I could tell them about cannibalism!
Stuff about our guts and also how it affects our brains. Idk why the idea of little microbes or parasites in our guts telling us what to do is fascinating to me. Also, did you know our gut has its own rudimentary “brain” called the “enteric nervous system”? Cool stuff.
The Mind-Gut Connection by Emeran Mayer
Gulp by Mary Roach
Gut by Giulia Enders
This Is Your Brain On Parasites by Kathleen McAuliffe (goes beyond the gut but also includes stuff about gut parasites and how they may be influencing us)
Omg thank you for commenting I was actually searching for a good book on gut health!
