“ There are few chemicals that we as a people are exposed to that have as many far reaching physiological affects on living beings as Monosodium Glutamate does. MSG directly causes obesity, diabetes, triggers epilepsy, destroys eye tissues, is genotoxic in many organs and is the probable cause of ADHD and Autism. Considering that MSG’s only reported role in food is that of ‘flavour enhancer’ is that use worth the risk of the myriad of physical ailments associated with it? Does the public really want to be tricked into eating more food and faster by a food additive? ”
