Myth: Avoid Chinese food during pregnancy.
Truth: My answer to this is simple. If Chinese people can eat Chinese food and have normal pregnancies and healthy babies, then why can’t we? Even so, I suggest that you avoid ajinomoto (monosodium glutamate), which is commonly used in Indian Chinese cuisine. It is an excitatory neurotransmitter that destroys nerve cells in the brain.
