Question: Is it safe to eat Asian foods and other foods that contain MSG?

Monosodium glutamate (MSG) is the sodium salt of the amino acid "glutamate". It is used as a flavor enhancer in a variety of foods. Glutamate itself is found naturally in many living things such as our own bodies and protein-containing foods, such as cheese, milk, meat, peas, and mushrooms. Unlike salt or other seasonings, MSG does not alter the actual taste of food.

Instead, it enhances taste by exciting and increasing the sensitivity of taste buds. MSG works much like a drug, altering taste buds’ sensitivity. This affects the flavor perceptions of the person who has ingested food or drink that contain MSG. It basically tricks your brain into thinking the food you are eating tastes good. While not all people react to the current MSG levels found in foods, about 30% of the population does develop adverse reactions, including:

tingling, warmth and weakness
facial pressure or tightness
upset stomach
chest pain
headache
nausea
rapid heartbeat
difficulty breathing (in MSG-intolerant people with asthma)
drowsiness

MSG has been classified by the Food and Drug Administration's (FDA) GRAS
(Generally Recognized as Safe for consumption) list, along with other GRAS substances such as sugar, salt, and baking soda. However, if you have had problems tolerating high MSG foods prior to pregnancy, it would be advisable to avoid MSG during pregnancy. Pregnant women are advised to use MSG in moderation and to drink extra water to help offset the high sodium intake of MSG-containing foods. When preparing food at home, check labels. Legally, MSG must be clearly documented. When dining out, some restaurants will label selections that are MSG-free, but you should also ask specific questions before making your menu selection.
