Paper Intake of food additive preservatives and incidence of cancer: results from the NutriNet-Santé prospective cohort (open) https://www.bmj.com/content/392/bmj-2025-084917

Associations: potassium sorbate, potassium metabisulfite, sodium nitrite, potassium nitrate, acetic acid, and sodium erythorbate
