Oil is a form of writing. I know this because I can read it in my blood, urine, and shit. As part of research for a recent book, I tested myself for a wide range of chemicals. I also had my microbiome sequenced. I found petrochemical pollution in my blood and urine in the form of pesticides, flame retardants, phthalates, and more. I discovered evidence in my gut of shifted microbial communities associated with aspects of the Western diet. I wrote about what I found in a book called Anatomic, which I will discuss in more detail in the next post.
