Filling in the knowledge gaps between what we eat and the diseases we develop may lie in our guts, literally. The human large intestine houses the largest reservoir of microorganisms in or on the human body. With a 100-fold greater gene count than humans, the gut microbiome has huge potential to place a large metabolic burden (or advantage) on its host. ⋯ Evidence from recent dietary intervention studies suggest adopting a plant-based, minimally processed high-fibre diet may rapidly reverse the effects of meat-based diets on the gut microbiome. However, recent work has shown that individual diet responses may be complicated by host genetics and the wide variation in the gut microbiome. Now that we measure genes and microbes more accurately, we are embarking on an exciting era of using both food and microbes as potential therapies.
