Can you be allergic to food additives?
Food additive intolerance is a non-IgE mediated food hypersensitivity. The hypersensitivity is induced by the food additives via a direct mast cell activation. Although the exact pathophysiology is unknown, various clinical signs are characteristic of food additive intolerance.
Which food additives could be allergic?
- Food dyes and colorings (such as tartrazine, annatto, and carmine)
- Antioxidants (such as BHA and BHT)
- Emulsifiers and stabilizers (such as gums and lecithin)
- Flavorings and taste enhancers (such as MSG, spices, and sweeteners)
- Preservatives (such as benzoates, nitrites, and acids)
