Microbiome Reset, Letter staycuriousmetabolism.substack.com/p/how-im-rebuilding-my-microbiomeafter?r=40ekz2
Description:
Microplastics are everywhere—in our food, water, and inside our bodies—and avoiding them completely is nearly impossible. In this conversation, I sit down with Dr. Matthew Dunn PhD, a molecular biologist working at the intersection of biotechnology and human health, to unpack what the science actually says about microplastics and how they may be linked to cardiovascular disease, reproductive health issues, and gut inflammation
We break down the landmark human data, the animal and cellular studies that help explain possible mechanisms, and dissect the state of the data.
We also explore a potential inside-out solution: using specific probiotic strains to bind microplastics in the gut and help eliminate them before they cause harm, along with practical steps anyone can take today to reduce exposure without spiraling into fear.
Chapters:
0:00 – The Microplastics Problem: Why This Matters
2:00 – Microplastics and Heart Disease (NEJM Evidence)
6:38 – Reproductive Health Red Flags: Fertility, Pregnancy, Offspring
11:00 – Microplastics in the Gut and Microbiome Disruption
15:00 – How Microplastics Damage the Intestinal Lining
17:46 – Experimental Evidence for “Leaky Gut”
20:00 – Can Probiotics Bind and Remove Microplastics?
31:33 – What We Don’t Know Yet: Limits of Human Evidence
34:38 – Microplastic Testing: What Can (and Can’t) Be Measured
36:24 – Practical Ways to Reduce Microplastic Exposure Today
