"Here, we introduce the latest studies on the gut microbiota in children with allergic diseases and present the hypothesis that dysbiosis characterized by fewer butyric acid-producing bacteria leads to fewer regulatory T cells, resulting in allergic disease.
Our study and a study reporting that children with butyric acid-rich stool samples at 18 months of age tend to have fewer sensitized allergens support our hypothesis. If this hypothesis is correct, using prebiotics and probiotics to increase BAPB [butyric acid-producing bacteria] levels and postbiotics that are rich in butyric acid might be novel preventative or therapeutic approaches to allergic diseases."
NOTE: Foods supporting butyrate producing bacteria include BUTter, asparagus, artichoke, onions, potatoes, yams, legumes (and other *resistant* starches). And more.
