Worst Food Series 4: Monosodium Glutamate (MSG)

By: Elna Botes van Schalkwyk

Monosodium Glutamate

This flavor enhancer is most often associated with Chinese food, but it's actually in countless processed food products ranging from frozen dinners and salad dressing to snack chips and meats. MSG is an excitotoxin, which means it overexcites your cells to the point of damage or death, causing brain dysfunction and damage to varying degrees -- and potentially even triggering or worsening learning disabilities, Alzheimer's disease, Parkinson's disease, Lou Gehrig's disease and more.

Part of the problem is that free glutamic acid (MSG is approximately 78 percent free glutamic acid) is the same neurotransmitter that your brain, nervous system, eyes, pancreas and other organs use to initiate certain processes in your body. Although the US Food and Drug Administration (FDA) continues to claim that consuming MSG in food does not cause these ill effects, many other experts say otherwise.
