Monosodium Glutamate
What is Monosodium Glutamate?
Monosodium Glutamate, commonly known as MSG, is the sodium salt of glutamic acid, an amino acid found naturally in many foods. It is usually made by fermenting starches or sugars like sugar beet, cane, or molasses.
MSG is widely used as a flavor enhancer that brings a savory taste known as umami, commonly found in various processed foods, soups, and snack items. The chemical structure of MSG is the same whether it's in processed foods or naturally present in foods like tomatoes and cheese. Scientific evidence on MSG's health impact varies, with some studies linking it to symptoms like headaches in high doses, though it's generally recognized as safe for most people.
When you see MSG on a label, it's usually added to intensify flavors. For those sensitive to MSG, consuming it in large amounts can lead to mild symptoms like headaches or flushing, though such reactions are rare.
