MSG has long been a staple in any Asian kitchen. An alternative to salt, this sodium-based seasoning is the key ingredient to providing that authentic flavour to any Asian dish, particularly Thai foods. However, MSG has been vilified by Western cooks for many years, shrouded in mystery due to flawed reports of headaches and other misleading health concerns. Thankfully, people are learning, with the help of science-backed research, that MSG is not the enemy they initially thought it was. Instead, at-home cooks are picking up the famous ingredient and levelling up their Thai cooking. Below explore some of the debunked myths surrounding MSG and learn how to incorporate this versatile seasoning into your authentic Thai dishes.

What is MSG?

MSG, or monosodium glutamate, is the sodium salt of glutamic acid, an amino acid naturally present in everyday foods like tomatoes, mushrooms, and cheese. When dissolved into food, it boosts the savoury taste known as umami, a fifth basic flavour that takes dishes from bland to mouthwatering. MSG’s journey began in Japan with scientist Kikunae Ikeda, who isolated the compound from seaweed broth in the early 1900s, hoping to capture and replicate the savoury complexity found in his favourite dishes. Since then, MSG has become a staple across Asia, offering home cooks and professional chefs alike a quick route to that authentic restaurant flavour.

The Culinary Power of MSG in Thai Cooking

MSG’s popularity in Thai cooking comes from its ability to enhance the overall taste of a dish. When a soup or curry feels a little bland, a sprinkle of MSG can magically intensify the rich, savoury notes that make Thai food so addictive. Dishes such as Tom Yum soup, Thai curries, Pad Thai, and countless street food staples often feature MSG to bind together bold flavours. Even classics like stir-fried Pad Kra Pao, pineapple fried rice, and spicy salads like Larb may benefit from MSG’s subtle lift, bringing out the best in satay sauce, fish sauce, and all manner of fragrant Thai ingredients.

MSG Myths and Scientific Facts

Despite MSG’s proven track record in kitchens, myths and misconceptions linger. The idea of “Chinese Restaurant Syndrome”, where MSG triggers headaches and discomfort, gained traction in the West through flawed studies decades ago. In reality, these health scares lack solid evidence. Worldwide agencies, including the FDA and WHO, officially recognise MSG as safe for consumption within recommended limits. Most symptoms commonly attributed to MSG are found to be unrelated, and adverse reactions are extremely rare. Science-backed research has repeatedly shown that MSG, when used as intended in cooking, poses no threat to those enjoying Thai food at home or in restaurants.

MSG Use in Home Cooking and Eating Out

The use of MSG varies between home kitchens, restaurants, and street stalls. Street food vendors and some restaurants often use MSG for its convenience, while home cooks may prefer to enhance the umami with natural alternatives or none at all. Cost and accessibility play a role, but so does consumer preference. Thai cuisine remains adaptable, evolving to accommodate dietary sensitivities or individual preferences. When eating out, customers can ask about the use of MSG and try experimenting at home with umami-rich ingredients like fish sauce, soy sauce, mushroom powder, or tamarind to balance flavours without MSG.

Making Informed Choices

Thai food’s vibrant palate comes from a careful combination of ingredients; MSG is just one note among many. Whether cooking at home or dining out, consumers have the freedom to make flavour choices that fit their own dietary needs and preferences. This flexibility keeps Thai cuisine welcoming and inclusive, as vegan, vegetarian, gluten-free, dairy-free, and MSG-free options are increasingly available across restaurants and home recipes. This makes Thai food an excellent choice for those who want to experiment with their daily dinners.
