 The intestinal microbiome has been linked to various chronic diseases such as inflammatory bowel disease, IBD, obesity, type 2 diabetes, cardiovascular disease and cancer. Dietary changes can also cause rapid changes in the microbiome, suggesting potential therapeutic applications. This review examines the effects of certain diets on the intestinal microbiome, finding that specific foods can produce predictable shifts in existing host bacterial which can then affect host immunity and metabolism. This knowledge could be beneficial to both patients and practitioners. This article was authored by Rosnick Keising, Hin Wenchang, Di Yang, and others.
