Data from the 1960s and 1970s demonstrate that monosodium glutamate causes hypothalamic damage, endocrine disruption, and behavior disorders when given to immature animals after either subcutaneous (59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81) or oral (67,73,74,76,82,83,84,85,86) doses.
