A note on the magical molecules deemed short-chain fatty acids, like butyrate. They’re made as metabolites of beneficial gut flora like bifidobacteria, which spawn to digest the varied fibers in a plant-based food stream. Short chain fatty acids are shown to improve lipid metabolism, insulin sensitivity, and food satiety thereby alleviating metabolic syndrome. They also promote integrity of the intestinal epithelium to prevent permeability and corresponding systemic inflammation. Short chain fatty acids are described in this fascinating analysis which is more broadly about gut flora and obesity. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7333005/
