This NPR Life Kit podcast episode discusses a study published in Nature Microbiology on the impact of diet on gut microbiome health. The interview with a health correspondent details how consuming a wide variety of plant-based foods, regardless of meat consumption, improves gut bacteria linked to better health (reduced inflammation, stronger immunity). Dietitians recommend aiming for five different plant-based foods daily, including fruits, vegetables, beans, seeds, nuts, and whole grains; frozen options are equally beneficial. The episode emphasizes the importance of dietary diversity for a healthier gut and suggests practical ways to incorporate more plant-based foods into daily meals and snacks. Listeners gain actionable advice for improving their gut health through simple dietary changes.
