What is the 30 plants a week challenge and does it actually work?

The “30 plants a week challenge” is a social media trend rooted in scientific research that encourages people to eat 30 or more different plant-based foods each week to boost gut health by increasing the diversity of healthy gut bacteria. The challenge includes a wide range of foods such as fruits, vegetables, beans, whole grains, nuts, seeds, herbs, spices, dark chocolate, and coffee, and is supported by lifestyle medicine experts for its evidence-based benefits. Participants are advised to track their intake and gradually increase fiber-rich foods to allow the gut microbiome to adjust. The challenge is promoted by programs like Corewell Health’s “Plant Powered Challenge,” aiming to help people adopt healthier dietary patterns and improve overall well-being.
