Guest guest Posted August 11, 2008 Report Share Posted August 11, 2008 If it says on the label: " aspartic acid " you shouldn't use it. You don't even have to consider what I say, this is what Dr. Russell Blaylock, neurosurgeon, says. " Excitotoxins: The Taste That Kills " , www.russellblaylockmd.com - an entire book on aspartic acid and glutamate, both excitotoxins, and a few others like cysteine. Everyone who cares about health should read it. He also has an excellent newsletter. You simply can't isolate aspartic acid. This is why Dr. John Olney fought so hard to stop the approval of aspartame. He did this study and at that time founded the field of neuroscience called excitotoxicity. (I'll continue below the study.) Also, the combination of aspartic acid and glutamate can really damage a baby's brain. You should read Dr. Olney's 49 page report on www.mpwhi.com, front page banner. It was written to the Board of Inquiry of the FDA, who agreed with it. Read on. Brain Damage in Infant Mice Following Oral Intake of Glutamate, Aspartate or Cysteine By John W. Olney, MD Striking degenerative changes in the infant mouse retina after subcutaneous treatment with monosodium glutamate (MSG) were reported by Lucas and Newhouse in l957(1). Other studies (2-4) established that the process of retinal degeneration induced by MSG treatment is a remarkably acute and irreversible form of neuronal pathology. Recently it was found that a similar process of acute neuronal necrosis occurs in several regions of the infant mouse brain after subcutaneous treatment with MSG, and that animals treated with high doses in infancy tend to manifest obesity and neuroendocrine disturbances as adults (7,8). The arcuate nucleus of the hypothalamus is an area particularly vulnerable to glutamate induced damage in infant animals of several spices (mice and rats (7), rabbits and chicks and the rhesus monkey (3) ), In mice, which have been studied more extensively for MSG induced disturbances than other species, the infant animal suffered hypothalamic damage from a relatively low subcutaneous dose (0.5 g/kg of body weight) (7). Because of the widespread practice of weaning human infants on foods which are not only rich in natural glutamate content but may contain substantial quantities of glutamate (MSG) added for flavouring (10,11), it is important to establish whether damage to the infant central nervous system could follow from oral as well as from parenteral administration of glutamate (12). We describe here experiments which demonstrate hypothalamic damage in infant mice following relatively low oral doses of glutamate, and also report that orally administered aspartate and cysteine can induce retinal and hypothalamic damage. Seventy-five Webster Swiss albino mice, 10 to 12 days old, were given single oral doses of a 10 per cent aqueous solution of MSG at one of 5 dose levels (0.25, 0.5, 0.75, 1.0 or 2.0 g/kg). Ten control animals were intubated but given no treatment, and an additional 46 were given single oral doses of other test compounds, as shown in Table 1. Accurate dosage control was ensured by use of an improvised flexible gastric tube inserted gently through the mouth and esophagus into the stomach. About 5 h after treatment, each animal was anaesthetized with chloral hydrate and killed by perfusion fixation of the central nervous system with 1.5 per cent glutaraldehyde and 1 per cent paraformaldehyde in 0.1 M cacodylate buffer. After 15 min of perfusion, the retinas and brain areas of interest were further fixed in osmium tetroxide and processed by a technique described elsewhere' which permits alternative examination of any specimen by either light or electron microscopy. To provide a rough 3 g/kg., Aspartate and cysteine, however, were striking exceptions because each animal treated with these compounds developed both retinal and hypothalamic lesions which seemed identical to those which are usually found after treatment with MSG. The possibility that glutamate and aspartate are additive in their toxic effect was suggested by the observation that every one of eight animals treated orally was a mixture of MSG (0.5 g/kg) and sodium aspartate (0.5 g/kg) developed a degree of hypothalamic damage characteristically seen in animals treated with either agent as l g/kg (Table 1). Curtis (13) and others have found that glutamate, aspartate and cysteine comprise a select group of amino acids (the " neuroexcitatory " amino acids) which can depolarize nerve membranes. Whether the striking ability of this select group of compounds to induce neuronal necrosis in the immature central nervous system relates to their ability to depolarize nerve membranes need further study. Because glutamate is a naturally occurring constituent of dietary protein there has been little tendency to question its safety for human infant consumption. But, in our experiments, both glutamate and aspartate are toxic to the infant mouse at relatively low levels of oral intake and, when taken together, these common amino acids have an additive brain damaging effect. Contrary to conclusions which others have reached from studies on adult animals (12) these experiments with tube fed infant animals raise serious questions concerning the advisability of supplementing the human infant diet with MSG.

End of Study ______________________ Dr. Olney and Dr. Madelin Price, a biochemist with impeccable credentials on her own, who worked with Dr. Olney for 38 years have done many studies on aspartic acid. I have several. Just like you can't isolate aspartic acid because its an excitotoxin, neither can you isolate phenylalanine that is in aspartame. Granted its 50% in aspartame which is why it does so much damage because you might have 5% in meat or milk or whatever, but this really floods the brain, lowering the seizure threshold and depleting serotonin. Isolated in any amount it a neurotoxin. The reason I'm telling you this is people will argue about the small amount of phenylalanine in products, and companies will argue with you, and they will give all sorts of reasons. Of course, phenylketonurics who can't metabolize phenylalanine could really be damaged, the reason for the PKU warning on aspartame. Anyway, I've passed some of these arguments on to Dr. Madelin Price who retired a couple of years ago after working by Dr. Olney's side for almost four decades. She always wrote back and said if its phenylalanine you can't isolate it. The last time I sent her a really big argument I really had to smile with her answer: " Phenylalanine is phenylalanine is phenylalanine. It cannot be used in any product! " This is the same thing as aspartic acid. The reason aspartame is so deadly is the components are either neurotoxic or excitoxic. It's an excitoneurotoxic carcinogenic drug. The molecule breaks down to DKP which is a brain tumor agent. Put it this way after working all these years with the experts and reading everything they write, I personally would not use any product with aspartic acid or phenylalanine. Anyone who does should do it at their own risk.
