Some people have reported mild, short-term symptoms after consuming MSG, but under clinical testing, people were not more likely to respond to MSG than to a placebo. Once a true food allergy has been diagnosed, strict avoidance of the offending food is the only treatment. To do this, read food labels carefully and consistently. For additional information, contact the food company. When eating out, ask about ingredients and how the dish was prepared.
Ingredient substitution is a useful skill for the food allergy sufferer.
A registered dietitian can guide you toward appropriate food substitutions. Specialty food product suppliers can provide product suggestions. This information is not a tool for self-diagnosis or a substitute for professional care.
