(NaturalNews) Despite common perception, the toxic food additive MSG is everywhere – not just in Chinese food! This taste enhancer is actually hidden under dozens of ingredient names in all sorts of processed foods, restaurant foods, beverages, chewing gums, vitamins and supplements. It is added to foods in higher dosages than ever before, and more and more people are experiencing symptoms.
To understand why processed Free Glutamic Acid is associated with so many health problems, it is helpful to learn about natural Glutamic Acid – an amino acid (a building block of protein) that occurs naturally in the body as one of many excitatory neurotransmitters (chemicals that "excite" cells into action). Glutamic Acid occurs naturally in certain unprocessed, whole foods (e.g., tomatoes). In this natural form, it is bound (i.e., linked) together with other amino acids to form a protein. Once ingested, the protein is broken down slowly by the digestive system. The Glutamic Acid is released gradually into the blood stream and is non-toxic. If one ingests more than the body needs, the cells clear away the excess just as they were designed to do. The digestion of these natural, whole food sources releases such a small amount of Glutamic Acid that even people who react to processed MSG can usually tolerate them.
When food manufacturers break down a protein (usually from corn, soy or wheat) to make processed Free Glutamic Acid, they "free" the glutamic acid from the links that bind it to other amino acids in nature. When one ingests this already-broken-down, free form of Glutamic Acid, blood levels of glutamate can spike to more than 20 times the usual amount because the digestive system does not have to work to break down the links. The human nervous system is not equipped to handle such quickly-absorbed doses. The excess glutamate cannot be efficiently cleared away, so it accumulates around the cells throughout the body, over-exciting them to the point of damage or death.
This disruption at the cellular level leads to a range of physiological reactions that may be as minor as a runny nose or as life-threatening as a heart attack. According to experts like Dr. Russell Blaylock, M.D., Free Glutamic Acid is a toxin, not an allergen. Some people are more sensitive to lower dosages than others, but it affects everyone to some degree. There is often a delay between ingestion and onset of symptoms, preventing many people from realizing the connection. Most acute symptoms will display within 48 hours (many within 30 minutes) of ingestion, but some health effects (e.g., obesity, infertility) have been demonstrated in lab mice long after exposure.
Because glutamate receptors line various organs and tissues (brain, heart, lungs, reproductive organs, digestive tract, etc.) throughout the body, ingesting processed Free Glutamic Acid can disrupt just about any system and cause a wide variety of symptoms. Luckily, much of this damage is reversible, and many sufferers resolve their symptoms (often within 7-10 days) by completely eliminating Free Glutamic Acid from their diets. To prevent these effects and to avoid this hidden additive, one must prepare meals at home from basic, whole food ingredients; minimize reliance on processed foods; read every ingredient list; and avoid any mysterious or vague ingredients on product labels.
