## 3. Frequently Asked Clinical Questions
### Q: Does Polysorbate-80 cause weight gain without extra calories?
**A:** Peer-reviewed studies in Nature demonstrated that chronic intake of Polysorbate-80 alters microbiota gene expression toward flagellin production, promoting low-grade metabolic inflammation and visceral adiposity.

### Q: How do I avoid Polysorbate-80 at Costco and Walmart?
**A:** Check the final three lines of any creamy dressing, ice cream, or sauce label for 'Polysorbate-80', 'Polysorbate-60', or 'Mono- and Diglycerides'.
