Consumption of MSG does not have a detrimental effect on health as long as a person does not have any food allergies to it, says nutritionist Hena Nafis.

In addition, Nafis also pointed out that the US Food and Drug Administration (FDA) considers the addition of MSG to foods to be ’generally recognized as safe’ (GRAS).
Dharini Krishnan, president of the Indian Dietetic Association, based in Chennai, said, "In addition to packaged foods, people have been consuming MSG in its natural form as well. It is found in tomatoes, Parmesan cheese, mushrooms and many other vegetables and fruits. MSG is generally a flavor enhancer, and is either found in natural sources or added artificially."
The industry watchdog Food Safety Standards Authority of India had taken more samples of Maggi across India for testing after certain harmful substances were allegedly found in a batch in quantities higher-than-permissible-limits, said the government. Nestle, manufacturer of Maggi, said, "We understand that consumers are concerned by reports that the authorities in Uttar Pradesh have found elevated levels of lead in a sample pack of Maggi noodles. We are fully cooperating with the authorities who are conducting further tests and we are awaiting their results."
