What are symptoms of msg allergy
Monosodium glutamate (MSG) is a flavor enhancer and is often found to be an additive in numerous foods or used in cooking. When consumed in large amounts it can cause adverse effects on those who are sensitive to it. Among the signs of a reaction, you might experience a feeling of warmth, flushing, headaches and chest pain. Fairly often MSG is found in Chinese cuisine, so those sensitive to this additive must request that it is excluded from the food preparation.
Another additive that may cause an allergic reaction is sulfites, which might happen naturally or be added to enhance crispness or to prevent it from spoiling. Sulfites are often used as a preservative in numerous foods and beverages.
Sulfites can be found in such products as wine, beer, and dried fruits. For those with sulfite allergies or intolerances, consuming a sulfite-containing product in large amounts may lead to in-breathing. This is of even greater concern for those with asthma, who already are predisposed to difficulty in breathing.
While food allergies are often diagnosed through blood tests, there are no tests available to diagnose a food dye, MSG or sulfite allergy. For this reason, one must hold a dependable diary of foods they eat and reactions that may result.
This will then assist them to determine which food additive may be the cause of such a reaction. Don't attempt to diagnose yourself; instead, talk to your doctor about your symptoms and about what testing she may recommend.

You may be surprised to study that reactions to monosodium glutamate (MSG) are not truly allergic. Instead, reactions to MSG may be caused by toxicities to the nervous system or even by an irritant effect on the esophagus—although, experts own not teased this every out yet.
The Symptoms of MSG "Allergy"
Many people describe adverse reactions after consuming MSG, commonly (and pejoratively) referred to as “Chinese Restaurant Syndrome” because MSG has traditionally been used in Asian cooking. But the truth is that most people who are affected will experience only mild and short-lasting symptoms correct after eating foods containing MSG.
These symptoms may include:
- Heart palpitations
- Facial pressure
- A sense of generalized weakness
- Numbness on the back of the neck, shoulders, and arms
- Chest pain
In fact, only a few studies own shown that mild reactions may happen after large amounts of MSG is consumed. In other words, the threshold for symptom development is typically far above what would be consumed during a normal meal that contains MSG.
Finally, it's exciting to note that in addition to these symptoms, MSG intake has been linked to specific health disorders.
For instance, research exists that glutamate levels are high in people with migraines and tension-type headaches.
Some experts own also linked high muscle glutamate concentrations with certain chronic musculoskeletal pain disorders love temporomandibular disorders—although, research on this phenomenon has not panned out much.
Lastly, blood pressure has been shown to increase with MSG consumption. But this rise in blood pressure is short-lived and occurs with high MSG intake.
Testing for MSG Allergy
Because sensitivity to MSG is not generally accepted as a true allergy, there is no test available to determine whether you are sensitive to it.
For example, skin tests and blood tests are not available as they are with other food and environmental allergies. While it is possible to act out an oral challenge to MSG, this is not done extremely often.
The Skinny on MSG
MSG, or monosodium glutamate, is a flavor enhancer comprised of the sodium salt of glutamic acid. More specifically, MSG is a naturally occurring amino acid that is produced by fermenting starch, sugar beets, sugar cane, or molasses, a process similar to that used to make yogurt, vinegar, and wine.
Because there is extremely little evidence that a true MSG allergy exists, the Food and Drug istration (FDA) has classified MSG as an ingredient that's "generally recognized as safe." However, because its use has historically provoked controversy, the FDA requires food labels to list it as an ingredient.
Although, one caveat worth mentioning is that foods that naturally contain MSG do not need to list MSG as an ingredient, although the product label cannot claim "No MSG" or "No added MSG."
Additives That May Cause Reactions
Allergic reactions own been found to happen in some people after they consume three dyes in particular: carmine, FD&C Yellow #5 and annatto.
Carmine, also known as natural red 4, is actually derived from the scale of dried insects. While this seems strange, it has been used in food since the 16th century.
Red dye #4 is found in foods such as burgers and sausages, drinks and candy. Typically it is found in foods with shades of red, pink or purple. An allergy to carmine has been reported to result in both minor and significant reactions, including anaphylaxis.
FD&C Yellow #5, also known as tartrazine, is one of two yellow food dye allergies. The symptoms associated with this allergy include reports of hives and swelling. This dye is often found in candy, canned vegetables, cheese, ice cream, ketchup, and boiling dogs.
Annatto is the other yellow food dye that has been associated with allergies.
It comes from the seeds of the achiote tree and it is responsible for giving foods a yellow-orange color. Reports of several cases of anaphylactic reactions own been associated with this dye. Annatto can be found in cereals, cheeses, snack foods, and drinks.
It is significant for those with food dye allergies to realize that this allergy is not limited to just food and medications. Numerous personal care products, such as soaps and lotions, as well as cosmetics love eyeshadow, blush and nail polish, can also contain these same dyes. The same is true for household products as well, such as cleaning supplies, crayons, and shampoo.
Being familiar with how to read labels and what products to pay attention to are both extremely significant for those with food dye allergies.
Those who are having food dye reactions may experience mild or severe reactions. Among the most common symptoms, you will discover reactions such as headaches, itchy skin, swelling of the face or hives.
Severe reactions are similar to those of other food allergy reactions such as difficulty breathing, dizziness, fainting, low blood pressure, and trouble breathing. As in other allergic reactions, anaphylaxis can result, so immediate medical attention should be sought at the first sign of a reaction.
How to Avoid MSG Reactions
Staying away from MSG is the only preventative measure you can take to avoid a reaction The excellent news is that FDA labeling requirements make it easier to avoid foods that contain MSG, but eating in restaurants may prove to be trickier.
Also, remember, while food labels must list it as an ingredient if MSG is added to that food, naturally occurring foods with MSG (for example, tomatoes) do not need to list it.

Despite the favorite belief that MSG is an allergy, or that it's even linked to a reaction, there is really no excellent scientific data to back this up. That said, sometimes misconceptions exist for a reason, meaning there is likely some truth underlying the MSG phenomenon, and we simply own not figured it every out yet.
In the finish, this may be a situation where you follow your gut instinct. If foods containing MSG give you a headache or other unpleasant symptom, by every means, avoid it.
On the same token, if you do accidentally ingest MSG, be helpful to yourself.
Next time, attempt to take a closer glance at the label or enquire specifically about MSG if you are in a restaurant.
MSG is found naturally in numerous foods, including seaweed, tomatoes, and cheese, as well as numerous canned vegetables, soups, and processed meats.
Despite widespread anecdotal evidence that some people experience reactions, studies on MSG own not demonstrated a clear cause-and-effect relationship.
What is food allergy testing?
A food allergy is a condition that causes your immune system to treat a normally harmless type of food as if was a dangerous virus, bacteria, or other infectious agent.
The immune system response to a food allergy ranges from mild rashes to abdominal pain to a life-threatening complication called anaphylactic shock.
Food allergies are more common in children than adults, affecting about 5 percent of children in the United States. Numerous children outgrow their allergies as they get older.
Almost 90 percent of every food allergies are caused by the following foods:
- Tree nuts (including almonds, walnuts, pecans, and cashews)
For some people, even the tiniest quantity of the allergy-causing food can trigger life-threatening symptoms. Of the foods listed above, peanuts, tree nuts, shellfish, and fish generally cause the most serious allergic reactions.
Food allergy testing can discover out whether you or your kid has a food allergy.
If a food allergy is suspected, your primary care provider or your child’s provider will probably refer you to an allergist. An allergist is a doctor who specializes in diagnosing and treating allergies and asthma.
