Monosodium glutamate (MSG) is a food additive commonly used to enhance the flavor of processed and packaged foods. While it is generally recognized as safe by regulatory authorities, some individuals may experience side effects after consuming MSG. These side effects are usually mild and temporary, but can include headaches, flushing, sweating, numbness or tingling, and a sensation of pressure in the face or chest. These symptoms are often referred to as "MSG symptom complex" or "Chinese restaurant syndrome." It's important to note that most people can consume MSG without any negative effects, but those who are sensitive may want to minimize their intake of foods containing MSG or opt for MSG-free alternatives. If you have specific concerns about the effects of MSG or any other food additive, it's always best to consult with a healthcare professional.
