Beneficial Effect of Potato Consumption on Gut Microbiota and Intestinal Epithelial Health

Diet plays an important role in shaping the gut microbiota, which has been called a separate organ due to its profound effects on host health. Potato, being a rich source of phytonutrients and bioactive food components, becomes a functional food for improving gut microbiota and gut health. Potato phytonutrients and bioactive food components contribute to gastrointestinal health through direct interactions with the epithelium or indirectly through modulation of the gut microbiota, and microbially derived metabolites, such as short chain fatty acids (SCFAs). In addition, gut microbiota degrade polyphenols and phytonutrients, and increase their bioavailability and thus the functionality of complex macronutrients. This review discusses the potential role of potato in shaping gut microbiota, strengthening intestinal epithelial barrier function, and thereby improving gastrointestinal health.
