Does Chinese Food Give You a Headache?
I get headaches whenever I eat in Chinese restaurants. Is there something in Chinese food that causes headaches?
June 19, 2000 -- Yes: the food additive, monosodium glutamate (MSG), which
is found in everything from spicy kung pao chicken to tangy sweet and sour
pork. Chefs use MSG to enhance the flavor of your favorite dishes.
That's because MSG consists of a mixture of sodium and the amino acid
glutamate. Together, they form a very powerful flavor enhancer, changing almost
any food from bland to tasty.
Many people, however, pay more than just the restaurant check for their
MSG-enhanced gastronomic pleasure. For some, the price includes a headache and
numbness in the back of the neck, which can radiate down the arms and back.
Other people report symptoms of mild to severe headaches, tightness in the
chest, pressure around the cheeks or jaw, mild mood changes, weakness,
tingling, burning sensations, heart palpitations, or vivid and bizarre dreams.
A few people report asthma-like symptoms after consuming even small amounts of
the food additive.
These temporary but uncomfortable symptoms are often so subtle that people
don't realize the additive has affected them, which makes it hard to determine
precisely how many people are sensitive to MSG. However, this reaction to MSG
is widespread enough to have a name: Chinese restaurant syndrome.
If you're sensitive to MSG, reduce your intake of the additive or stay away
from it entirely. Physicians haven't established a safe range because it varies
from person to person. Generally speaking, the larger the amount of MSG, the
more likely it is that you will be sensitive to it and will develop symptoms,
which can surface just minutes after ingesting MSG. And people with high blood
pressure or those who must watch their sodium levels should limit their MSG
intake as well.
If your symptoms become really bothersome, consider consulting an allergist.
Or try eliminating all MSG-containing foods from your diet for at least two
weeks. This will take a bit of sleuthing. MSG goes by a variety of names and is
hidden in many foods, making it difficult to avoid all the sources. It's sold
in your grocery store under the brand name "Accent." On food labels,
MSG is also listed as autolyzed yeast extract, hydrolyzed vegetable protein or
HVP, potassium glutamate, sodium caseinate, broth, natural flavorings, or
