People are seen in the window eating at a Chinese restaurant decorated with menu items on its shop front on Friday Jan. 10, 2020, in New York City. A social media campaign backed by a Japanese seasonings company is targeting the persistent idea that Chinese food is packed with MSG and can make you sick. So entrenched is the notion in American culture, it shows up in the dictionary: Merriam-Webster.com lists “Chinese restaurant syndrome.” as a real illness. But much of the mythology around the idea has been debunked: monosodium glutamate, also known as MSG, shows up in many foods from tomatoes to breast milk, and there’s no evidence to link it to illness.
