Cysticercosis is a sickness caused by ingesting the tapeworms found in pork. When tapeworm larvae spreads to the human brain, it is a very serious problem resulting in a condition referred to as neurocysticercosis. If a tapeworm infestation problem exists, there are medications sold over-the-counter for this problem.
Glutamate. Glutamate is an excitatory relative of GABA. It is the most common neurotransmitter in the central nervous system-as much as half of all neurons in the brain-and is especially important in regards to memory. Curiously, glutamate is actually toxic to neurons, and an excess will kill them.
Contrary to Deb A's posting, glutamic acid (glutamate) is one of the 20 amino acids making up proteins/enzymes in nature. It is also the most common neurotransmitter in the brain. While glutamate is in MSG, glutamate does not equal MSG. I am a vegetarian and to Carol H I say that I eat nutritional yeast (yum!) yet I do not make the claim that humans are not meant to eat meat, quite the contrary.
