If you’ve struggled with bloating, constipation, or diarrhea, you’re not alone — IBS and other gut disorders have become the norm.
Nick Norwitz, MD PhD, breaks down new research revealing a surprising culprit — and potential treatment — for Irritable Bowel Syndrome (IBS): serotonin-producing gut bacteria.
Scientists have discovered that a specific pool of serotonin made by certain bacteria in your intestines can influence digestion, motility, and even mood. When this system is out of balance, it may trigger IBS symptoms.
It’s not a silver bullet — but it’s a breakthrough that could change how we treat gut health.

![Can Fiber Damage Your Liver?

We’re told fiber is always good—but that’s not the full story. A landmark randomized controlled trial from Stanford tested different fiber types and found that one common fiber, when taken at high doses, significantly increased ALT, a marker of liver injury, in a subset of people. The effect was large enough that researchers stopped the study early for safety concerns.
At lower doses, the same fiber may improve insulin sensitivity and reduce fatty liver, highlighting a key takeaway in nutrition science: dose and individual response matter. This isn’t about fear—it’s about context over dogma.
