Gluten-free, Casein-free Diet
A gluten-free casein-free diet (GFCF diet), also known as a gluten-free dairy-free diet (GFDF diet), is a diet that does not include gluten (found most often in wheat, barley, and rye), and casein (found most often in milk and dairy products). Despite an absence of scientific evidence, there have been advocates for the use of this diet as a treatment for autism and related conditions. Uses Autism The majority of the available evidence does not support the use of this diet in the treatment of autism. * American Academy of Pediatrics – Clinical Report (2007) In their report, the AAP did not recommend the use of special diets for children with autism spectrum disorder because of inadequate evidence. * Cochrane Library – Gluten and Casein-free diets in autism spectrum disorder (2008) The Cochrane review found that while relatively commonly used the evidence to support the diets use in children with autism was poor. All studies as of 2006 had issues with them. * '' Research in Aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gluten
Gluten is a structural protein naturally found in certain Cereal, cereal grains. The term ''gluten'' usually refers to the elastic network of a wheat grain's proteins, gliadin and glutenin primarily, that forms readily with the addition of water and often kneading in the case of bread dough. The types of grains that contain gluten include all species of wheat (common wheat, durum, spelt, Khorasan wheat, khorasan, emmer, and Einkorn wheat, einkorn), and barley, rye, and some cultivars of oat; moreover, cross hybrids of any of these cereal grains also contain gluten, e.g. triticale. Gluten makes up 75–85% of the total protein in Common wheat, bread wheat. Glutens, especially Triticeae glutens, have unique viscoelasticity, viscoelastic and Adhesion, adhesive properties, which give dough its elasticity, helping it Proofing (baking technique), rise and keep its shape and often leaving the final product with a chewy texture. These properties, and its relatively low cost, make gluten v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelation Therapy
Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. Chelation therapy has a long history of use in clinical toxicology and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks, including the mobilization of mercury and other metals through the brain and other parts of the body by the use of weak chelating agents that unbind with metals before elimination, exacerbating existing damage. To avoid mobilization, some practitioners of chelation use strong chelators, such as selenium, taken at low doses over a long period of time. Chelation therapy also has a history of fraudulent use in Alternative medicine, to treat claimed effects of heavy-metal exposure on problems as disparate as heart disease, cancer and autism. Chelation therapy must be administered with care as it has a number of possible side effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casomorphine
Casomorphin is an opioid peptide (protein fragment) derived from the digestion of the milk protein casein. Health Digestive enzymes can break casein down into peptides that have some biological activity in cells and in laboratory animals though conclusive causal effects on humans have not been established. Some practitioners of alternative medicine claim that casomorphin may cause some of the symptoms of autism, and promote casein exclusion diets as a supposed cure, there was a lack of evidence that these diets had any effect. If opioid peptides breach the intestinal barrier, typically linked to permeability and constrained biosynthesis of dipeptidyl peptidase-4 (DPP4), they can attach to opioid receptors. Elucidation requires a systemic framework that acknowledges that public-health effects of food-derived opioids are complex with varying genetic susceptibility and confounding factors, together with system-wide interactions and feedbacks.

Opioid Peptide
Opioid peptides or opiate peptides are peptides that bind to opioid receptors in the brain; opiates and opioids mimic the effect of these peptides. Such peptides may be produced by the body itself, for example endorphins. The effects of these peptides vary, but they all resemble those of opiates. Brain opioid peptide systems are known to play an important role in motivation, emotion, attachment theory, attachment behaviour, the response to Stress (biology), stress and pain, Hunger (motivational state), control of food intake, and the rewarding effects of alcohol (drug), alcohol and nicotine. Opioid-like peptides may also be absorbed from partially digestion, digested food (casomorphins, Gluten exorphin, exorphins, and rubiscolins). opioid food peptides, Opioid peptides from food typically have lengths between 4–8 amino acids. Endogenous opioids are generally much longer. Opioid peptides are released by post-translational proteolytic cleavage of Protein precursor, precursor pr ...

Paul Shattock
Paul Shattock is a British autism researcher and scientific consultant to the charity Education and Services for People with Autism, of which he is also the founder. He was formerly the director of the Autism Research Unit at the University of Sunderland. He is well known for his disputed research into dietary therapy and autism, having claimed that autistic children may have a " leaky gut" which allows certain peptides to enter the bloodstream, and claimed that they excrete unusually high levels thereof. As a result of this speculation, he has promoted the use of a gluten-free, casein-free diet to ameliorate the symptoms of autism, a theory he developed along with Kalle Reichelt. In addition, he has claimed that a protein found in milk may play a role in the etiology of autism. He is also the former president of the World Autism Organization. In 2002, Shattock conducted a survey and claimed that this survey had identified a unique subset of autistic children who may be unique ...

Opioid Excess Theory
The opioid excess theory postulates that autism is the result of a metabolic disorder in which opioid peptides produced through metabolism of gluten and casein pass through an abnormally permeable intestinal membrane and then proceed to exert an effect on neurotransmission through binding with opioid receptors. Advocates of this hypothesis believe that autistic children are unusually sensitive to gluten, which results in small bowel inflammation in these children, which in turn allows these opioid peptides to enter the brain. Early years This hypothesis was first proposed by Jaak Panksepp in a 1979 paper, in which he speculated that autism might be "an emotional disturbance arising from an upset in the opiate systems in the brain". Kalle Reichelt then emerged as one of the leading advocates of this theory, publishing papers alleging that "the patterns of peptides and associated proteins from urinary samples rom people with autismdiffer considerably from each other and from norma ...

Opiate
An opiate is an alkaloid substance derived from opium (or poppy straw). It differs from the similar term ''opioid'' in that the latter is used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain (including antagonists). Opiates are alkaloid compounds naturally found in the opium poppy plant ''Papaver somniferum''. The psychoactive compounds found in the opium plant include morphine, codeine, and thebaine. Opiates have long been used for a variety of medical conditions, with evidence of opiate trade and use for pain relief as early as the eighth century AD. Most opiates are considered drugs with moderate to high abuse potential and are listed on various "Substance-Control Schedules" under the Uniform Controlled Substances Act of the United States of America. In 2014, between 13 and 20 million people used opioids recreationally, representing 0.3% to 0.4% of the global population between the ages of 15 and 65. According to the CDC, ...

Urine
Urine is a liquid by-product of metabolism in humans and many other animals. In placental mammals, urine flows from the Kidney (vertebrates), kidneys through the ureters to the urinary bladder and exits the urethra through the penile meatus (males) or urethral meatus of the vulva (females) during urination. In other vertebrates, urine is excreted through the cloaca. Urine contains water-soluble by-products of Cell (biology), cellular metabolism that are rich in nitrogen and must be clearance (medicine), cleared from the Circulatory system, bloodstream, such as urea, uric acid and creatinine. A urinalysis can detect nitrogenous wastes of the mammalian body. Urine plays an important role in the earth's nitrogen cycle. In balanced ecosystems, urine fertilizes the soil and thus helps plants to grow. Therefore, Reuse of excreta, urine can be used as a fertilizer. Some animals use it to territory (animal)#Scent marking, mark their territories. Historically, aged or fermented urine (kn ...

Jaak Panksepp
Jaak Panksepp (June 5, 1943 – April 18, 2017) was an Estonian-American neuroscientist and psychobiologist who coined the term "affective neuroscience", the name for the field that studies the neural mechanisms of emotion. He was the Baily Endowed Chair of Animal Well-Being Science for the Department of Veterinary and Comparative Anatomy, Pharmacology, and Physiology at Washington State University's College of Veterinary Medicine, and Emeritus Professor of the Department of Psychology at Bowling Green State University. He was known in the popular press for his research on laughter in non-human animals. Early life and education Panksepp was born in Tartu, Estonia on June 5, 1943. His family escaped the ravages of post-WWII Soviet occupation by moving to the United States when he was very young. He initially studied at University of Pittsburgh in 1964, and then completed a Ph.D. at the University of Massachusetts. Research Panksepp resisted establishment forces in animal rese ...

Peptide
Peptides are short chains of amino acids linked by peptide bonds. A polypeptide is a longer, continuous, unbranched peptide chain. Polypeptides that have a molecular mass of 10,000 Da or more are called proteins. Chains of fewer than twenty amino acids are called oligopeptides, and include dipeptides, tripeptides, and tetrapeptides. Peptides fall under the broad chemical classes of biological polymers and oligomers, alongside nucleic acids, oligosaccharides, polysaccharides, and others. Proteins consist of one or more polypeptides arranged in a biologically functional way, often bound to ligands such as coenzymes and cofactors, to another protein or other macromolecule such as DNA or RNA, or to complex macromolecular assemblies. Amino acids that have been incorporated into peptides are termed residues. A water molecule is released during formation of each amide bond.. All peptides except cyclic peptides have an N-terminal (amine group) and C-terminal (carboxyl g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metabolism
Metabolism (, from ''metabolē'', "change") is the set of life-sustaining chemical reactions in organisms. The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the elimination of metabolic wastes. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their Structures#Biological, structures, and respond to their environments. The word ''metabolism'' can also refer to the sum of all chemical reactions that occur in living organisms, including digestion and the transportation of substances into and between different cells, in which case the above described set of reactions within the cells is called intermediary (or intermediate) metabolism. Metabolic reactions may be categorized as ''catabolic''—the ''breaking down'' of compounds (for example, of glucose to pyruvate by c ...
