I had been quite suspicious of MSG for quite sometime... According to that second link I posted, MSG does cause memory loss.
Under dietary guidelines it says: "Avoid eating foods that contain such additives as artificial sweeteners, monosodium glutamate (MSG), preservatives, and artificial colors. These chemicals can accumulate in the body and become toxic, causing brain damage and memory loss."



p.s. vitamin b6 is a natural diuretic.
so if you eat a lot of foods containing b6 and you feel as if you have trouble staying hydrated... this could be one possible explanation.
