Scientists link emulsifiers in processed foods to allergy and immune disorders

Review identifies common food additives in ultra-processed foods—particularly emulsifiers like carrageenan and polysorbate 80—as key drivers of gut dysbiosis, inflammation, and allergic diseases by disrupting intestinal barriers and activating proinflammatory pathways.
