Guest guest Posted December 23, 2004 Report Share Posted December 23, 2004 What? Tooth enamel is composed of calcium phosphate. What is the evidence she cites that reduced protein intake results in a reduction of enamel production? It was my understanding that enamel loss was the result of brushing too hard, and/or from presence of acid. curious, tev --- Vegigran <vegigran wrote: > <<<<I'd like to get people that believe in all > the different things like high fat, no/low fat, > differing protein levels and run tests are there > ways to test for protein deficiencies?>>>>> > Virginia Vetrano states > it's the lack of protein and cites examples of it. > Maybe we do need more protein than we think.

The dissollution of enamel on teeth show the inadequate composition (lacking protein) of the salivary secretions. I would think that due to a poor quality of protein that most of us received on the SAD diet, our protein reserves by the time we get to a certain age are pretty much depleted. It's probably true that we could live on 10-15 per cent, if our diets had been ideal from the start, but how many of us were!

Isn't a prime rib cooked rare, high quality protein? Also, what are you refering to when you say protein reserves?

Guest guest Posted December 23, 2004 Report Share Posted December 23, 2004 <<<<<Poor quality protein on SAD? Isn't a prime rib cooked rare, high quality protein?>>>>> The protein of animals is very acidic, again back to the nuetralizing with calcium. Our protein is built from amino acids. Animal protein has already been built and must be taken apart as it is different from the human protein chain. If it is cooked and coagulated, it cannot be taken apart. It also creates a lot of toxins besides the acidity. Easier on the body and energy to just start from scratch and build from plant amino acids and not have to do all that breakdown and alkalizing. That's why I think by the time we start on a healthy pathway, our bodies are probably pretty low on quality protein and maybe that's why we are experiencing some of the difficulties that we are on this raw vegan diet. Also, what are you refering to when you say protein reserves? I've never heard about the body storing anything more than glocogen and fat. Virginia Vetrano says in her book " that every living cell and all the body fluids except bile and urine, contain protein. Our muscles, our vital organs, and the endocrine glands are composed principallly of proteins. We would be nude and limp without proteins because they are used to make our skin and bones. They are the major constituents also of the hair and nails, connective tissue, the blood cells and the serum. Our proteins form a part of every membrane in our body including the cell membrane, the nuclear membrane, and all the other membranes withing the cell. So, it naturally follows that in order to keep living we need sufficient proteins in our diet to have the right kinds of amino acids for both growth and maintenance of our magnificient organisms. " So I would say it just stands to reason with our bodies continually repairing and replacing it's self, that we must have a constant reserve of amino acids ready to be used for the many different kinds of protein that the body must build out of them.

Guest guest Posted January 12, 2005 Report Share Posted January 12, 2005 Protein isn't what enamels our teeth according to this article: http://www.scielo.br/scielo.php?script=sci_arttext & pid=S1516-14392003000300011 1. Introduction Tooth enamel is the most mineralized tissue of human body. Its composition is 96 wt.% inorganic material and 4 wt.% organic material and water. In dentin, the inorganic material represents 70 wt.%. This inorganic material is mainly composed by a calcium phosphate related to the hexagonal hydroxyapatite, whose chemical formula is Ca10(PO4)6·2(OH) 1. X-ray energy dispersive spectroscopy (EDS) analysis of enamel and dentin also indicated the presence in small quantities of other elements such as Na, Cl and Mg 2. Since the article states that tooth enamel is 96% inorganic material, I wonder what she is basing her theory on? Perhaps the proteins are architect proteins? Or messenger proteins, which activate helper cells to produce enamel? regards, tev Chemical Composition.—According to von Bibra, enamel consists of 96.5 per cent. of earthy matter, and 3.5 per cent. of animal matter. The earthy matter consists of phosphate of lime, with traces of fluoride of calcium, carbonate of lime, phosphate of magnesium, and other salts. According to Tomes, the enamel contains the merest trace of organic matter. http://www.bartleby.com/107/pages/page1120.html --- Vegigran <vegigran wrote: > > > <<<<What is the evidence she cites that reduced > protein intake results in a reduction of enamel > production?>>>>>> > > She says its the high quality of protein in the > saliva that re-enamels our teeth.

Guest guest Posted January 12, 2005 Report Share Posted January 12, 2005 I found this which seems to confirm her idea about salivary proteins (It appears that the proteins are architectural in function. Very interesting.): Dental enamel proteins are the proteins which, during tooth enamel formation, are secreted by specialized cells (ameloblasts) of the tooth bud and define the space which eventually becomes dental enamel. In ways, still not fully understood, these proteins form an extracellular matrix which both induces the mineralization of the structure with crystals of carbonated calcium hydroxyapatite and also appears to organize the orientation and spacing of these crystals at the ultrastructural level. http://www.fincham.co.uk/biochemistry.htm --- tev treowlufu <coac2002 wrote: > > > Protein isn't what enamels our teeth according to > this article: > > http://www.scielo.br/scielo.php?script=sci_arttext & pid=S1516-14392003000300011 > > 1.
