I think this is largely just because I’m a health geek and strive to fuel my body as efficiently as possible. But with that said, also how junk food and preservatives affect the gut biome, because trust me, I still get my fair share.

This is a really interesting article. I also feel that it is a very dependable because it was done through a university.
