Food Additive Sensitivity Basics
Food additive sensitivity basics link colors, preservatives, and sugar alcohols to dose-dependent symptoms—single-additive trials beat sweeping ultra-processed fear.
Food additive sensitivity basics cover dose-dependent reactions to colors, preservatives, emulsifiers, or sugar alcohols in some people—headache, flushing, or gut urgency—without IgE allergy mechanisms. Diagnosis is messy; single-additive trials beat removing entire grocery aisles from influencer lists.
Sugar alcohols like sorbitol cause osmotic diarrhea at portions common in protein bars. Keep calories and protein adequate during trials.
Common questions
-
