So I fell off my rigid SCD diet this last week and spent the week eating burritos, tacos, chips, and hot sauce!
This morning, as I felt my intestines churning, I thought "what have all of these hot peppers done to my improved microbiome?", so I did some research.
This, from 2017, looks positive: Gut Microbiota Mediates the Protective Effects of Dietary Capsaicin against Chronic Low-Grade Inflammation and Associated Obesity Induced by High-Fat Diet ncbi.nlm.nih.gov/pmc/articl...
This, from 2020, is incomprehensible: Study on the Effect of Capsaicin on the Intestinal Flora through High-Throughput Sequencing pubs.acs.org/doi/pdf/10.102...
I like hot sauce, so for now I will likely go with the 2017 study.
