What is a disadvantage of msg?

A disadvantage of monosodium glutamate (MSG) is that some individuals may experience sensitivity to it, leading to symptoms such as headaches, flushing, and nausea, often referred to as "Chinese restaurant syndrome." Additionally, concerns have been raised about potential long-term health effects, although research has not conclusively proven these claims. Despite extensive studies deeming it safe for most people, MSG remains controversial in certain dietary communities.
