Is MSG safe? Food scientists bust common myths about the popular seasoning

For decades, Monosodium Glutamate (MSG), popularly known as Ajinomoto in India, has been the controversial villain of the kitchen pantry. Linked to a myriad of unverified health scares, it has been widely shunned by health-conscious consumers. However, as culinary science evolves and people turn back to home cooking, food scientists and culinary experts are setting the record straight: MSG is not only safe but may also be the key to healthier, more flavourful meals. Dr Jamuna Prakash, Food Consultant and Professor at the Department of Food Science and Nutrition, University of Mysore, told LiveMint that the reluctance towards MSG is a classic example of how public perception can outpace and ignore scientific reality. "Many reasons behind reluctance can be explained by stories and testimonies of the past, which gained a lot of popularity without having any scientific basis whatsoever," explained Dr Prakash. From a scientific standpoint, Dr Prakash said MSG is one of the most extensively researched ingredients in the world. It has been consistently acknowledged as safe by premier global food safety authorities, including the UN’s Food and Agriculture Organization (FAO), the World Health Organization (WHO), and India’s FSSAI.
“MSG is produced through a process of fermentation involving ingredients of plants such as sugarcane, cassava, or sugar beet, in the same way as the fermentation process involved in making food items such as yoghurt or pickles,” Dr Prakash noted. Indians have ‘always cooked with Umami’ Chef Ajay Chopra, a celebrated restaurateur and TV personality, argued that long before the term "umami" was coined, Indian kitchens were already mastering it. He told LiveMint that umami is simply the taste of completeness—that comforting, rich flavour that anchors a bowl of dal or a slow-cooked curry. "To most of us, umami is an experience which has been with us throughout our lives, although we never gave it a name before," Chef Chopra said. “Whether it be tomatoes, mushrooms, onions, fermented batter, matured cheeses, soy sauce, or meat broths, the combination of these ingredients adds taste to the dish. For me, umami is the taste of completeness. It does not dominate the dish, but harmonises the flavours together.” Chef Chopra pointed out that the natural tendency to build dishes full of depth—from the delicate ‘yakhni’ of Kashmir to the robust gravies of Chettinad, the seafood of Konkan, and the ‘amti’of Maharashtra—has always relied on layered flavouring.
“We now simply have a scientific name for what generations of Indian home cooks have done instinctively,” he said. ‘MSG is just pure umami’ One of the most compelling arguments for bringing MSG back into the kitchen is its functionality as a healthier alternative to regular table salt, especially as consumers look for smarter ways to cook at home. "Everyone wants to prepare food that is both healthy, functional, and full of flavour, without having to spend long hours preparing it," explained Chef Chopra. “MSG is a naturally occurring seasoning made through a fermentation process, which means that MSG is just pure umami.” Dr Prakash echoed this from a nutritional standpoint, highlighting that MSG contains about 70% less sodium than regular table salt. Because our bodies process the glutamate in MSG exactly the same way they process the glutamate in a fresh tomato, it functions as a highly efficient flavour enhancer. When used wisely in daily cooking, this combination of culinary flavour and food science empowers home cooks to significantly reduce the overall sodium content of their dishes, making healthy cooking less restrictive and more enjoyable.
