Interpretive Summary: Healthy foods are of increasing importance to a growing number of consumers. A negative perception of a food can lead to decreased demand. In recent years, the human “microbiome” has been intensively researched internationally and found to have a large effect on human health. Scientists at Washington State University and with the USDA-ARS in Prosser, Washington summarize their findings on the effect of potatoes on the gut microbiome. The work supports a role for potatoes in improving gastrointestinal health and positively influencing the gut microbiome.
Technical Abstract: Diet plays an important role in shaping the gut microbiome, which has been called “a separate organ” due to its profound effects on host health. Potato, being a rich source of phytonutrients including resistant starches, dietary fibers, and polyphenolics, becomes a functional food for improving gut microbiota. Potato phytonutrients and their metabolites contribute to gastrointestinal health either through direct interactions with the epithelium or indirectly through modulating the gut microbiome. Gut microbiota degrade polyphenolics and other phytonutrients, and increase their bioavailability and thus functionally of the complex macronutrients. In addition, these microbial derived metabolites, such as short chain fatty acids (SCFAs), strengthen barrier function via multiple mechanisms. This review discusses the potential role of potato phytonutrients in shaping gut microbiota, strengthening intestinal epithelial barrier function, and thereby improving gastrointestinal health.
