Collected Reports of Endocrine Disorders, Retinal Degeneration,

and Adverse Reactions Caused by MSG

Ingestion of processed free glutamic acid (MSG) is known to produce a variety of adverse reactions in some people. These reactions, although seemingly dissimilar, are no more diverse than reactions found as side effects of certain neurological drugs. We do not know why some people experience reactions and others do not. We do not know whether MSG "causes" the condition underlying the reaction, or whether the underlying condition is simply aggravated by the ingestion of MSG. We only know that the reactions listed below are sometimes caused or exacerbated by MSG.

All forms of MSG (free glutamic acid that occurs in food as a consequence of manufacture) cause these reactions in MSG-sensitive people. That includes MSG found in a plant "growth enhancer" called AuxiGro, and MSG found in a variety of other fertilizers and fungicides that have been approved for spraying on growing crops, including crops identified as "organic."

Endocrine disorders; conditions such as *GROSS OBESITY*, stunted growth, *LEARNING DISABILITIES*, and behavior disorders caused by MSG-induced damage to the endocrine system; and glaucoma and *RETINAL DEGENERATION* (possibly leading to blindness) are not classified as "adverse reactions." When caused by MSG, their roots lie in the destruction of brain cells, possibly years before gross obesity, stunted growth, learning disabilities, behavior disorders, and/or retinal degeneration are first observed.

Research confirming that MSG consumed by laboratory animals causes brain lesions in the area of the hypothalamus has been replicated many times. Research that has claimed to find that MSG is "safe" has always been seriously flawed; and has always been financed, directly or indirectly, by the glutamate industry.

Obesity, reproductive disorders, and learning impairment, that sometimes become obvious only after puberty, may have their origins in neuroendocrine dysfunction caused by exposure of infants and small children to MSG.

If It's Safe, Why Do They Disguise It On Labels?

Slow Poisoning

If the label says “natural flavorings,” it is the common euphemism for MSG. In hundreds of studies around the world, scientists were creating obese mice and rats to use in diet or diabetes test studies.

No strain of rat or mice is naturally obese, so the scientists have to create them. They make these morbidly obese creatures by injecting them with MSG when they are first born.  The MSG triples the amount of insulin the pancreas creates, causing rats (and humans?) to become obese.

I checked my grocery store and found that MSG is in everything! The Campbell’s soups, the Hostess Doritos, the Lays flavored potato chips, Top Ramen, Betty Crocker Hamburger Helper, Heinz canned gravy, Swanson frozen prepared meals, Kraft salad dressings, especially the “healthy low fat” ones.

The items that didn’t have MSG had something called Hydrolyzed Vegetable Protein, which is just another name for Monosodium Glutamate. It was shocking.

When our family went out to eat, we started asking at the restaurants what menu items had MSG. Many employees, even the managers, swore they didn’t use MSG. But when we asked for the ingredient list, which they grudgingly provided, sure enough MSG and Hydrolyzed Vegetable Protein were everywhere. Burger King, McDonald’s, Wendy’s, Taco Bell, every restaurant, even the sit down ones like TGIF, Chilis,’ Applebees and Denny’s use MSG in abundance. Kentucky Fried Chicken seemed to be the WORST offender: MSG was in every chicken dish, salad dressing and gravy. No wonder I loved to eat that coating on the skin. Their secret spice was MSG.

In the book The Slow Poisoning of America by John Erb, he says that MSG is added to food for the addictive effect it has on the human body. Even the propaganda website sponsored by the food manufacturers lobby group supporting MSG (at explains that the reason they add it to food is to make people eat more.

And we wonder why the nation is overweight? The MSG manufacturers themselves admit that it only addicts people to their products. Not only is MSG scientifically proven to cause obesity, it is an addictive substance! Since its introduction into the American food supply fifty years ago, MSG has been added in larger and larger doses to the prepackaged meals, soups, snacks and fast foods.

The FDA has set no limits on how much of it can be added to food. They claim it’s safe to eat in any amount. Many studies mentioned in John Erb’s book link MSG to diabetes, migraines and headaches, autism, ADHD and even Alzheimer’s.

The big media doesn’t want to tell the public, fearing legal issues with their advertisers. If you are one of the few who can still believe that MSG is good for us, go to the National Library of Medicine, at Type in the words “MSG Obese,” and read a few of the 115 medical studies that appear.
