Whole Grain Bread, Fiber, Fruit May Contribute to Healthy Gut Microbiome Diversity
While there is still much to learn about the gut microbiome, what we do know is that certain microbes appear to be more beneﬁcial than others, and that a large diversity of diﬀerent microbes seems to be protective. To ﬁgure out what constitutes a “normal” gut microbiome, European researchers combined microbiome data from nearly 4,000 people across the US and Western Europe. The researchers found that even within this large sample size, they have not yet uncovered the total richness of gut diversity. The scientists also analyzed a number of lifestyle and health factors to see if they might aﬀect microbiome composition. After medication use and stool consistency, dietary factors (preference for whole grain bread, high ﬁber intake, and high fruit intake) were pinpointed as probable contributors of healthy gut diversity.
