Eating the Rainbow: Why Colorful Foods Matter for Your Gut Health

Have you ever heard the phrase “eat the rainbow” when it comes to fruits and vegetables?

It’s not just a catchy saying—it’s actually solid advice for your health. Eating the rainbow means including a wide variety of colorful plant-based foods in your diet. Each color represents different nutrients, antioxidants, and plant compounds that support your body in unique ways.

But there’s more to it than just nutrition. Research shows that some of the healthiest people in the world have the most diverse gut microbiomes. In other words, a varied diet supports a richer, more balanced population of gut bacteria—and that diversity plays a big role in digestion, immunity, and even mood.

So, how can you start eating the rainbow?

We’ve created a simple chart to guide you on the best way to add more colorful fruits and vegetables to your meals. It’s easier (and more delicious) than you might think!
