Symptoms of an MSG Allergy

Monosodium glutamate, also known as MSG, is a flavor enhancer for food. Traditionally found in Asian cuisine, MSG is present in canned vegetables, soups, processed foods and meat, among others. MSG acts as a stimulant to nerve cells and brain, creating hunger or a yearning for certain foods like an addiction. Individual allergic sensitivity varies, though the U.S. Food and Drug Administration has found no related long-term health problems.

Effects

• Short-term reactions include flushing, sweating, heart palpitations, shortness of breath, dizziness, severe headache or a feeling of head expanding and contracting (pulsing). Individuals more susceptible to an adverse reaction are those with other allergies or asthma.

Time Frame

• Depending on the individual, reactions can occur immediately or up to 48 hours later.

Considerations

• For some individuals, an adverse reaction comes quickly. Others might react with cumulative exposure of the additive. There is no method to diagnose or treat a food chemical reaction. Keep a food journal and discuss concerns with a doctor or board-certified allergist.

Features

• White and crystalline like salt or sugar, MSG is made from fermenting starch and corn syrup. MSG is always present in autolyzed yeast, hydrolyzed vegetable protein, sodium caseinate and corn oil. It may be present in malt extract, malt flavoring and whey protein.

Prevention/Solution

• Read food labels and avoid purchasing or consuming products with MSG listed as an ingredient. In restaurants, request food items without MSG. Know other terminology used where MSG is present, such as seasoning, spices and maltodextrin.
