E621 Monosodium L-glutamate or MSG

What is Monosodium L-glutamate (MSG)?

Monosodium glutamate (MSG) is a sodium salt of L-glutamic acid and is widely used as a flavor enhancer in various foods, especially in Asian cuisine and processed products. MSG works by enhancing the savory taste of foods, making it a popular ingredient in soups, sauces, and snacks. Despite its widespread use, MSG has been the subject of controversy regarding its safety and potential health effects, leading to varying opinions on its inclusion in diets.

Why do I have an intolerance?

Intolerance to MSG can lead to a range of symptoms often referred to as "Chinese Restaurant Syndrome," which may include headaches, flushing, sweating, and numbness. Some individuals are particularly sensitive to MSG, leading to these symptoms even at small amounts. This sensitivity is believed to stem from the way MSG interacts with the body's glutamate receptors, potentially triggering excessive neural activity in some individuals.

What can I do about it?

To avoid symptoms of MSG intolerance, it is best to steer clear of processed foods and restaurant meals that typically contain this additive. Always check labels for MSG or terms like “hydrolyzed vegetable protein” that may indicate its presence. Focusing on whole, natural foods can help ensure a diet free from MSG, as cooking at home allows for full control over ingredients. Utilizing natural flavor enhancers like herbs and spices can also provide savory flavors without the use of MSG.
