What it is
Detergent-class synthetic emulsifier that keeps oil and water from separating across a long shelf life.
Why your biology objects
Emulsifiers are surfactants — they disperse the mucus lining your gut the same way they disperse oil. In mice this thins the protective mucus layer, lets bacteria reach the gut wall, and drives low-grade inflammation and metabolic shift. No food met your gut pre-emulsified before the 20th century.
