Evolutionary Discordance of Grains/Legumes in Diet - PART B

Evolutionary Discordance of Grains/Legumes in Diet - PART B

Up to this point, we have only briefly touched upon the role cereal grains have in inducing autoimmune disease (except for a brief look at celiac disease). There is substantial evidence (both epidemiological and clinical) showing the role cereal grains may play in the etiology of such diverse autoimmune diseases as multiple sclerosis (MS), insulin-dependent diabetes mellitus (IDDM), rheumatoid arthritis, sjogrens syndrome, dermatitis herpetiformis, and IgA nephropathy.

Although this proposal may at first seem preposterous, there is strong data to suggest that cereal grains may be involved in all of these diseases through a process of molecular mimicry whereby certain amino acid sequences within specific polypeptides of the gramineae family are homologous to (have the same structural form as) a variety of amino acid sequences in mammalian tissue. These homologous amino-acid (AA) sequences can ultimately confuse our immune systems so that it becomes difficult to recognize "self" from "non-self." When this happens, T-cells, among other immune-system components, launch an autoimmune attack upon a body tissue with AA sequences similar to that of the dietary antigen.

It seems that grass seeds (gramineae) have evolved these proteins with similarity to mammalian tissue to protect themselves from predation by mammals, vertebrates, and even insects. This evolutionary strategy of molecular mimicry to deter predation or to exploit another organism has apparently been with us for hundreds of millions of years and is a quite common evolutionary strategy for viruses and bacteria. It has only been realized since about the mid-1980s [Oldstone 1987] that viruses and bacteria are quite likely to be involved in autoimmune diseases through the process of molecular mimicry. Our research group has put together a review paper compiling the evidence (and the evidence is extensive) implicating cereal grains in the autoimmune process, and with a little bit of luck it should be published during 1998. [Editorial note as of June 1999: The paper has now been published; the citation is: Cordain L (1999) "Cereal grains: humanity's double-edged sword." World Review of Nutrition and Dietetics, vol. 84, pp. 19-73.]

Without the evolutionary template and without the evidence provided us by the anthropological community showing that cereal grains were not part of the human dietary experience, the idea that cereal grains had anything to do with autoimmune disease would probably have never occurred to us. This new electronic medium has allowed instant cross-fertilization of disciplines which probably would have rarely occurred as recently as five years ago.

Insulin Resistance- cause of ADD, diabetes, narcolepsy, etc etc

Insulin Resistance Insulin Resistance Have you been diagnosed with clinical depression? Heart disease? Type II, or adult, diabetes? Narcolepsy? Are you, or do you think you might be, an alcoholic? Do you gain weight around your middle in spite of faithfully dieting? Are you unable to lose weight? Does your child have ADHD? If you have any one of these symptoms, I wrote this article for you. Believe it or not, the same thing can cause all of the above symptoms. I am not a medical professional. I am not a nutritionist. The conclusions I have drawn from my own experience and observations are not rocket science. A diagnosis of clinical depression is as ordinary as the common cold today. Prescriptions for Prozac, Zoloft, Wellbutrin, etc., are written every day. Genuine clinical depression is a very serious condition caused by serotonin levels in the brain. I am not certain, however, that every diagnosis of depression is the real thing. My guess is that about 10 percent of the people taking

Could Narcolepsy be caused by gluten? :: Kitchen Table Hypothesis

Kitchen Table Hypothesis from www.zombieinstitute.net - Heidi's new site It's commonly known that a severe allergy to peanuts can cause death within minutes. What if there were an allergy that were delayed for hours and caused people to fall asleep instead? That is what I believe is happening in people with Narcolepsy. Celiac disease is an allergy to gliadin, a specific gluten protein found in grains such as wheat, barley and rye. In celiac disease the IgA antigliadin antibody is produced after ingestion of gluten. It attacks the gluten, but also mistakenly binds to and creates an immune reaction in the cells of the small intestine causing severe damage. There is another form of gluten intolerance, Dermatitis Herpetiformis, in which the IgA antigliadin bind to proteins in the skin, causing blisters, itching and pain. This can occur without any signs of intestinal damage. Non-celiac gluten sensitivity is a similar autoimmune reaction to gliadin, however it usually involves the

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed Scientists at John Carroll University, working in its Lighting Innovations Institute, have developed an affordable accessory that appears to reduce the symptoms of ADHD. Their discovery also has also been shown to improve sleep patterns among people who have difficulty falling asleep. The John Carroll researchers have created glasses designed to block blue light, therefore altering a person's circadian rhythm, which leads to improvement in ADHD symptoms and sleep disorders. […] How the Glasses Work The individual puts on the glasses a couple of hours ahead of bedtime, advancing the circadian rhythm. The special glasses block the blue rays that cause a delay in the start of the flow of melatonin, the sleep hormone. Normally, melatonin flow doesn't begin until after the individual goes into darkness. Studies indicate that promoting the earlier release of melatonin results in a marked decline of ADHD symptoms.
