Fiber, Polyphenols & Your Gut Microbiome: Part One

Are you feeding the right microbes — or the wrong ones?

In this episode of The Coach Debbie Potts Show, we’re kicking off a new two-part deep dive into how fiber and polyphenols shape your gut microbiome, your metabolism, and your long-term health.

Most of us have heard that “fiber is good for your gut,” but the truth is more nuanced. The type of fiber — and the type of gut you have — makes all the difference. For some, fiber can help feed beneficial bacteria that support digestion, immunity, and brain health. For others, especially those struggling with SIBO, IBS, or candida overgrowth, the wrong kind of fiber can worsen bloating, gas, or inflammation.

That’s where polyphenols come in — the colorful plant compounds found in berries, green tea, cocoa, and pomegranate. These act as a gentler “fertilizer” for beneficial microbes like Bifidobacteria and Lactobacillus, while helping keep harmful bacteria in check.

In Part One, we’ll cover:

• ✅ The difference between fibers and polyphenols in gut health

• ✅ Why your gut type determines your response to fiber

• ✅ How polyphenols can help reduce toxins like LPS (endotoxins) that drive inflammation

• ✅ Practical food swaps to support a healthier, more resilient microbiome

By the end of this episode, you’ll understand why one-size-fits-all fiber advice doesn’t work — and how you can use food color and polyphenols to start healing your gut from the inside out.
