                                According to research from the American Gut Project, individuals who consumed 30 or more different plant-based foods per week had a significantly more diverse gut microbiome than those eating fewer than 10. This discovery is the basis for the popular 30 plants a week challenge, which focuses on dietary variety for better health.
