Dr. Vivian Chen, a UK-based medical doctor with 14 years of experience, sat down with Liz Moody to cut through the noise around wellness trends. The core tension running through the entire conversation: the wellness world fixates on small, scary-sounding exposures while overlooking bigger levers that actually move the needle on health. "I feel like people are just hyper focused on very small things that in the big picture is not making that much difference," Chen says—pointing to PFAS in toilet paper as an example of something technically true but not worth worrying about until you've addressed the bigger sources.
Fiber Is the Unsung Hero—and It's Not Just About Digestion
Chen argues the wellness world is paying too much attention to protein and not nearly enough to fiber. "Just an additional ten grams of fiber in your diet can reduce your risk of dying by eleven percent," she says. Ten grams is roughly one avocado or half a cup of beans—not a heroic amount.

Do you know what the major sources of microplastics are in your home? Should you actually throw out your plastic cutting board? Are you ingesting heavy metals without even knowing it? Is your microwave hurting you?
I’m joined by Dr. Vivian Chen to get real answers about the toxins we're all a little worried about—microplastics, heavy metals, EMFs, PFAS, forever chemicals, water filtration, red light therapy, and the health myths worth knowing (and the ones you can let go of). If it's a toxin you're afraid of, we're getting into it. For more from Dr. Vivian Chen, subscribe to her Substack: https://platefulhealth.substack.com
🎧 What you'll learn:
- Why fiber might be your body's best defense against the microplastics you can't avoid
- The exact question to ask before buying a water filter (it's not "which one is best")
- Why your "healthy" non-stick pan might not be as safe as the brand claims
- The dosing mistake that means most red light therapy devices are doing NOTHING
- Why microwaving food in plastic is far riskier than cutting on a plastic board
- The 3-step hierarchy for actually lowering your PFAS exposure (toilet paper isn't on it)
