Monosodium glutamate (MSG) is a flavor enhancer added to thousands of the foods you and your family regularly eat. The chemical flavor enhancer has been linked to fibromyalgia, obesity, fatty liver, high insulin and blood sugar, metabolic syndrome, and neurological damage. It’s used in everything from canned soups, crackers, meats, and salad dressings, to baby food, infant formula, and your child’s school lunch. It is used to enhance flavors. Dr. Russell Blaylock, a board-certified neurosurgeon and author of “Excitotoxins: The Taste that Kills.” explains that MSG causes brain damage to varying degrees — and even triggers or worsens learning disabilities, Alzheimer’s disease, Parkinson’s disease, and more.
