Food manufacturers allow MSG or other forms of Free Glutamates, like Hydrolyzed Yeast Extract, Autolyzed Yeast Extract, Maltodextrin, the ubiquitous "spices" and "natural flavors", and others, to be added to their foods. The food labels do not always clearly state EXACTLY what is in their products.
Several million people are hyper-sensitive to Free Glutamates. MSG is composed of about 85% Glutamic Acid, so it has the highest concentration of it.
Many of these ingredients are toxic to many people. Symptoms range from migraine-like headaches, to atrial fibrillation (rapid and irregular heartbeat).
All we are asking for, is HONESTY in labeling.
