“…Kwok (1968) described the adverse behavioral effects, for example, headache and nausea, that can occur from the ingestion of monosodium L-glutamate. Green (1969), Powers (1973), and Von Hilsheimer (1974) reported case studies of children whose behavioral disturbances, irritability, hyperactivity, and short attention span improved following a dietary change consisting of a high-protein/low-carbohydrate diet and the inclusion of various vitamin supplements. Mikkelsen (1978), Greden (1974), and others have reported that paranoid delusions, headaches, anxiety symptoms, depression, and insomnia have been eliminated or dramatically reduced following the elimination or a reduction in the amount of caffeine consumed.…”
