Monosodium Glutamate: Nutrition, Pros & Cons
Monosodium Glutamate (MSG) is a popular flavor enhancer that delivers a savory 'umami' taste. Regulated by food safety authorities, it contains about 12% sodium by weight—approximately one-third of the sodium found in common table salt—making it a useful option for reducing overall sodium in prepared dishes without losing flavor.
