"Until we can clean up the planet and our act, we fortunately do have a “dirt cheap,” stop-gap way of coping with metal toxicity. That solution is diatomaceous earth. Dr. Knight has extensively tested a product produced by Perma-Guard that is also available through WisdomWays in Edgewood, Colorado.58 Diatomaceous earth comes from fossilized shells of freshwater diatoms and is found in vast deposits all over the earth. Made up of silicone and trace minerals, diatomaceous earth can, according to the scientific literature, absorb methyl mercury, E. coli, endotoxins, viruses (including poliovirus), organophosphate pesticide residues, drug residue, and protein, perhaps even the proteinaceous toxins produced by some intestinal infec- tions.59,60 The only caveat is that diatomaceous earth used for human or ani- mal detoxification must be food grade. People and other mammals should never use the coarse, crystalline form of diatomaceous earth sold for use in swimming pool filters or as insecticides, or sources of diatomaceous earth contaminated with toxins like arsenic and the metal toxins. If inhaled, the crystalline form can cause a disabling lung disease called silicosis and upon ingestion might puncture the lining of the alimentary tract. Food- grade diatomaceous earth binds metals and other toxins, gently siphoning or leaching them out of storage areas and passing them innocuously out of the body.61"
I consider this wild speculation at best. First off, th "PhD" author uses the word "silicone". Silicones are polyaklyl siloxane polymers that cure to rubbery substances I use to seal my engine gaskets. Also used in breast implants. Silicone is far different from what DE is truly composed, which are silicates !! A purported expert in DE, using the word "silicone" ?? LOL.
When it was stated: " according to the scientific literature" - no reference was given. What literature ? Perhaps if one spills the mercury from a thermometer into a bowl, on can throw DE into the bowl and the two might co-mingle, but that's far from what happens in a mammalian subject, so is it really relevant ?
Caveat is given concerning "crystalline form" of DE as being bad, but yet "food grade" is the supposed good stuff. Yet no discussion of the crystallinity of food grade material is mentioned. The implication to me is that food grade material is amorphous, yet, how would that be achieved ? Only vague , non-scientific statements are made. My understanding is that the food grade material is the same as the stuff that's dug out of the ground, except its been washed and analyzed.
Also, how does food grade DE "bind" to metals ? What metals ? Are they metal ions, or metallic elements in their metallic form ? Where are the equilibrium constants for Q1 and the beta expressions ??? !!! Do silicates ever function as chelants ? LOL If they "bind" then perhaps but look in any chemistry book and you'll not find mention of insoluble silicates (DE) ever being used as a chelating agent. I thus disagree that DE can bind metals with any more efficacy than could micronized beach sand. There are no known chelating groups in DE such as amino, sulfhydryl, cyano, carboxyl, etc. Can it selectively and preferentially remove "bad" metals that are bound to proteins and neural tissue ? So just how in the H does DE function to bind ? Where's the literature ? Why don't practitioners performing chelation therapy inject DE into the veins of their patients ? LOL.
The passage above ends with a reference "61", which is listed as a website. What am I supposed to do, read the whole website to find some statement that DE "gently siphoning or leaching them out of storage areas and passing them innocuously out of the body? " What are "storage areas? " Area is two-dimensional, like the area of a circle, yet the body is three-dimensional. Is there some plane in the body where bad metals are stored ? A surface somewhere ? How much area is there ? "Siphoning" ? That's a really dumb word to use, siphoning involves pressure differential. Wow, this DE sure does everything. Does it remove essential trace "metals" like copper, zinc, manganese from the body ? Any discussion of needing to replace such essential minerals once they've been allegedly bound by DE ? Typically , what gets mercury and lead, etc. also takes these with it, sometimes preferentially depending on the ligand. Fortunately with DE, it has no ligands, which explains why its a poor chelator or binder, if at all.
