Sodium Nitrite: Nutrition, Pros & Cons
Sodium nitrite is a widely used food preservative and color fixative in cured meats and processed fish. While highly effective at preventing the growth of harmful bacteria like Clostridium botulinum, its dietary intake should be strictly limited due to its association with the formation of carcinogenic nitrosamines and potential risks of chronic metabolic conditions.
