There is no problem in consuming small amounts of MSG (ajinomoto) during pregnancy
If MSG doesn't bother you when you're not pregnant, it certainly will not bother the baby! Monosodium glutamate
(MSG) is a natural component of many foods. It's a salt of the amino acid
glutamine, and we always have some MSG in our bodies. The Food and Drug Administration (FDA) has been testing MSG for years and rates it "generally recognized as safe." However, the FDA requires that all foods containing MSG include that information on the label, because some people develop an adverse reaction to it, whether pregnant or not.
Finally, there's no evidence that MSG is harmful to a developing baby.Even a large dose — which can cause nausea
even in someone who's not sensitive to it — wouldn't pose a known risk to a developing baby.
So relax, and enjoy the pregnancy,
