Monosodium Glutamate, often abbreviated as MSG, is a flavor enhancer commonly used in cooking. It is the sodium salt of glutamic acid, an amino acid found naturally in many foods like tomatoes and cheese. MSG is popular in Asian cuisine and processed foods because it intensifies savory flavors, making dishes taste richer and more delicious. While MSG is generally recognized as safe by health authorities, some people report sensitivity to it, experiencing symptoms like headaches or nausea after consumption. Despite these concerns, extensive research has shown that MSG is safe for most people when consumed in normal amounts, allowing many to enjoy its flavor-boosting benefits.
