Excitotoxins - The Taste That Kills-(a review of chapters 1 and 2)

Dr. Russell l. Blaylock, M.D. has written a compelling book detailing the results of numerous studies of the effects of what he calls "excitotoxins" in the brain. "Excitotoxins", such as (monosodium glutamate, commonly called MSG) glutamate and aspartate (such as the artificial sweetener, NutraSweet) are among the more than 70 special types of amino acids present in the brain that are known to be largely present in foods processed more available packaged today.

By defining precisely what are called "excitotoxins" in Excitotoxins: The Taste That Kills, (health Press, 1997) Dr. Blaylock leads the reader in an intensive course of brain in Chapter 1.Most of this chapter can be omitted truthfully from descriptions are very detailed and repeated once more chapters siguientes.Sin however, with a brief description of the parts of the brain (of frontal lobes, the parietal lobes, occipital lobes, temporal lobes, the cores arranged inside of brains, mother brain, pituitary gland and hypothalamus) and the composition of the neuron (Dendrite, Council of Cell, Axon and final terminal) we won a great appreciation for complexity and balances yet delicate operate within the human brain.

Chapter 1 Dr. Blaylock inform us that the brain consumes 20% of oxygen need body and 25% required glucose in the body to normal operations.Interestingly, this is the one piece of information we need to remember to Chapter 3. problem is that this tremendous need of oxygen and glucose circulating in the blood makes the brain vulnerable to ingested to toxins. In a section that describes the "blood/brain barrier" that we learned that this first line of defence against toxins-borne blood brain barrier and really can be filtered in certain circumstances that introduces another problem with these specific amino acids ingestion.

In Chapter 2 we received a review of aminoácidos.Esto is important since the "excitotoxins" really are amino acids which are normally present in the brain. Dr. Blaylock gives a brief overview of amino acids and how they are used to create the proteins in a process called anabolism building blocks. It is interesting to draw is collagen (the greatest body protein) which contains the amino acids of 1500.

Finally gives us an idea of what the potential problem as Dr. Blaylock explains another function of amino acids.Apparently, apart from being used to build proteins, some amino acids act as neurotransmitters.Glycine, glutamate and aspartate are examples of these types of aminoácidos.Dr.Blaylock describes in detail the neurotransmitter firing the proceso.También notes that neuroscientists have discovered glutamate is one of the most common neurotransmitters in the brain areas cerebro.muchas contain broad glutamate neuronas.A type turn, activation of cortical neurons glutamate activate other neurons within deep placed nuclei in the brain.

These connections are important to examine the effects of excitatory amino acids (such as MSG) and the origins of the neurological disease that reveal themselves in later chapters.

Seven daughters of Eve Book Review

The seven daughters of Eve is a book of nonfiction written by profession Brian Sykes of human genetics from the University of Oxford in England. Although a book of fiction with your kernel is not a pleasant blend of the history of the life of authors at the time when he was working the pioneer of mitochondrial DNA research and testing, there are fictional aspects to it.

The first half of the book is interesting that tells the story of how occurred type mitochondrial DNA testing and authors that helped advance research along personal life stories.E.g. after a motorcycle accident left Sykes with a bad shoulder as necessary to establish before flying, was able to take samples from a small island population that was useful to show how often in the Pacific Basin (well, actually how do not often) DNA muta mitocondrial.Es these true stories that allow the average reader to enjoy the book without being dominated by science, when summarized above says that a mother passes mitochondrial DNA in its entirety to all his children.

Given that mitochondrial DNA passed exactly a mother to her children, it is possible to return through the story and find what Sykes called the seven daughters of Eve. It was 7 women leading humans out of Africa, and helped to fill the rest of the world according to the book.

Sykes tries to give a name to each of these women and tell the story of his life based on what we know about the area that it is likely that lived as well as archaeological evidence since the time suggested by the number of mutations in the DNA sequence.While this part of the book was interesting, we see agriculture to start a story, dogs which are domesticated elsewhere, I found it harder to connect science that surrounded them, and then the real story of the life of Sykes.

It is a very interesting, faster reading, and then expect because Sykes is able to make reasonable and accurate sound science to explain his own history.Each reader is likely to encourage a different part of the book, but generally not read anything like genetic books long and boring and frustrating that so many of us have been with biología.Yo class would say that this is a final reading for anyone interested in human genetics.

Excitotoxins - The Taste That Kills-(A review of Chapter 3, how MSG kills brain cells)

According to the author, Dr. Blaylock, "Excitotoxins" are special amino acids such as glutamate and aspartate (which are commonly found in MSG and NutraSweet). These "Excitotoxins" are added to processed food to improve flavor. Normally act as neurotransmitters in the brain and spinal cord. However, when these common additives are consumed by eating certain processed foods) excessive amounts can develop to kill certain neurons in the brain by making them to fire several times (and unnecessary) until they die.

How to do this? Dr. Blaylock explains that there are two problems. First, we must understand glutamate is normally in the brain and the use to a neuron signal when it is time to shoot. When it's done is a cellular mechanism that transfers excess glutamate into surrounding glial cells. Glial cells weather neurons in the brain and supply them energy in the form of ATP). The amount of energy required to do this is very high.This indicates that the first problem is that in a condition of hypoglycemia (low blood sugar) is not enough ATP present to transfer the constant presence of glutamate glutamato.En neurons fire repeatedly until they die.

In particular, as part of the law process, glutamate and aspartate signal as a sort key to unlock the neuron that chemically start neurons fire (its normal task) calcium channels. The bomb cellular calcium active that remove calcium.This is the second problema.La calcium pump also requires an enormous amount of energy. A hypoglycemic condition these calcium pump would not operate allowing that neurons firing multiple times until you die.

The solution may seem to eat more, so there is never a State hypoglycemic.This may seem to be possible, but the reality is that (as says Dr Blaylock) the FDA has allowed to the food industry include these "excitotoxins" in so many hidden ways that consumers may not be aware that they are actually eating the same substances which usually try to avoid (MSG) this mass consumption glutamates and aspartates may be impossible to overcome with normal brain processes.A diet rich in natural unprocessed foods is very important.

The only real solution is to avoid consuming "excitotoxins."Dr. Blaylock indicated in Appendix 1 other additives of common foods that have been hidden MSG.estos sources include: Hydrolyzed, hydrolyzed plant protein, hydrolyzed protein, yeast extract, texture, protein and calcium caseinate, sodium caseinate Autolyzed Yeast and hydrolyzed avena.Algunos flour food additives plant protein can have MSG include: excerpt from Malta, Malt flavoring, Bouillon, broth, stock, flavoring, natural flavoring, natural meat or flavorings chicken and condiments.
