The mercury/casein/gluten factor effect on opioid
peptides as a mechanism in causing autism, schizophrenia,
Mercury and toxic metals block enzymes required to digest milk casein
and wheat gluten, resulting in dumping morphine like substances in the blood
that are neurotoxic and psychotic, as a major factor
in schizophrenia, autism, ADHD, and MS.
A direct mechanism involving
mercury’s inhibition of cellular enzymatic processes by binding with the
hydroxyl radical(SH) in amino acids appears to be a major part of the
connection to these allergic/immune reactive conditions(15-23,36,47,51,90). For
example mercury has been found to strongly inhibit the activity of xanthine oxidase and dipeptyl peptidase (DPP IV) which are required in the
digestion of the milk protein casein or wheat protein gluten (15,16,17,19,20,91,23-26,90,92),
and the same protein that is cluster
differentiation antigen 26 (CD26) which
helps T lymphocyte activation. CD26 or DPPIV is a cell surface glycoprotein
that is very susceptible to inactivation by mercury binding to its cysteinyl domain. Mercury and other toxic metals also inhibit
binding of opioid receptor agonists to opioid receptors, while magnesium stimulates binding to opioid receptors(15). Studies
involving large samples of patients with
autism, schizophrenia, or mania found that over 90 % of those tested had high
levels of the milk protein beta-casomorphine-7 in their blood and urine and
defective enzymatic processes for digesting milk protein(24,25,27), and
similarly for the corresponding enzyme needed to digest wheat gluten(24,26). Like casein, gluten
breaks down into molecules with opioid traits, called
gluteomorphine or gliadin.
As with caseomorphin, it too can retain biological
activity if the enzymes needed to digest it are not functioning properly..
Proteins in bovine milk are a
common source of bioactive peptides. The peptides are released by the digestion
of caseins and whey proteins (92). In
vitro the bioactive peptide beta-casomorphin 7 (
The studies found high levels of Ig A antigen specific antibodies for casein, lactalbumin and beta-lactoglobulin
and IgG and IgM for
casein. Beta-casomorphine-7 is a morphine like
compound that results in neural disfunction (24,25),
as well as being a direct histamine releaser in humans and inducing skin
reactions (14,21,25c). Similarly many
also had a corresponding form of gluten protein with similar
effects(24,26). Elimination
of milk and wheat products and sulfur foods from the diet has been found to
improve the condition(40,28,etc.).
A double blind study using a potent opiate
antagonist, naltrexone (NAL), produced significant
reduction in autistic symptomology among the 56% most
responsive to opioid effects(28). The behavioral improvements
was accompanied by alterations in the distribution of the major
lymphocyte subsets, with a significant increase in the T-helper-inducers and a
significant reduction of the T-cytotoxic-suppressors
and a normalization of the CD4/CD8 ratio.
Studies have found mercury causes increased levels of the CD8 T-cytotoxic-suppressors(29). As noted previously, such populations of
patients have also been found to have high levels of mercury and to recover
after mercury detoxification(23,11,30,40,91). As mercury levels are reduced the protein
binding is reduced and improvement in the enzymatic process occurs (91,11,96).
A mechanism in multiple sclerosis (MS) occurs due to a
reduction in immune system activity. Specifically, it is the reduction in the
number of the suppressor T-cells within the immune system that allows CD4
helper T-cells to do damage(31,97). Thus, during an
acute relapse the overall number of T-cells is reduced, the normal balance of
helper and suppressor T-cells is disrupted, and helper T-cells tend to
predominate. This is most pronounced during an acute relapse, but a
similar situation occurs although perhaps to a lesser extent, in chronic
progressive MS. Low dose naltrexone (LDN) has been
found to commonly be effective in reducing MS symptoms and exerbations,
apparently due its opioid suppressive effects(31). [ Chronic toxic
exposures to toxics such as mercury are one documented factor that can cause
such immune effects. Reducing chronic
exposures and detoxification have been documented to commonly bring improvement
in these conditions and in MS symptoms(97). ]
Studies have also found
heavy metals to deplete glutathione and bind
to protein-bound sulfhydryl SH groups,
resulting in inhibiting SH-containing enzymes and production of reactive oxygen
species such as superoxide ion, hydrogen peroxide,
and hydroxyl radical(39,43,45-47, 63-65,89,97,91). In addition to forming strong bonds with SH
and other groups like OH,NH2, and Cl in amino acids
which interfere with basic enzymatic processes, toxic metals exert part of
their toxic effects by replacing essential metals such as zinc at their sites
in enzymes. An example of this is mercury’s disabling of the metallothionein protein, which is necessary for the
transport and detoxification of metals.
Mercury inhibits sulfur ligands in MT and in the case of intestinal cell membranes
inactivates MT that normally bind cuprous ions(66),
thus allowing buildup of copper to toxic levels in many and malfunction of the
Zn/Cu SOD function. Another large study(51) found a high percentage of autistic and PDD
children are especially susceptible to metals due to the improper functioning
of their metallothionein detoxification process, and
that with proper treatment most recover.
Mercury has also been found to play a part in neuronal problems through
blockage of the P‑450 enzymatic process(67,89). Another
study found accelerated lipofuscin
deposition--consistent with oxidative injury to autistic brain in cortical
areas serving language and communication(97). Compared
with controls, children with autism had significantly higher urinary levels of
lipid peroxidation. Double-blind, placebo-controlled
trials of potent antioxidants--vitamin C or carnosine--significantly
improved autistic behavior.
