Frequently Asked Clinical Questions

Q: Why is carrageenan in almond and oat milk?

Manufacturers use 0.02%–0.1% carrageenan to keep water and plant fats from separating on warm warehouse shelves without paying for higher nut concentration.

Q: Is undegraded food-grade carrageenan safe for IBS or leaky gut?

Even food-grade carrageenan partially degrades in stomach acid (pH 1.5–2.5) and triggers IL-8 cytokine release in individuals with existing gut sensitivity.
