Distractions from nutrition – a timeline

Goals for the chronically ill often are different than for those who enjoy typical health – avoiding a cold is less difficult than avoiding increased inflammation that can lead to an inability to digest food, or to heal small wounds, or to grow skin in areas where skin cells are replaced on a weekly basis such as in mucous membranes of the nose or mouth or in the ear canal. Those rapidly growing areas represent all of the lining of the intestinal tract. If your skin isn’t healing well from minor scrapes and you have frequent nose bleeds then likely your entire digestive tract isn’t in good shape either. Cells are replaced throughout the body on a regular basis but some areas have a longer life cycle for the replacement than other areas.

(Non-healing sores may be more common in autoimmune condition Lupus, patient forum, may also occur with vasculitis – migraines may involve vasculitis. Patient forums for people with odd diseases can be comforting if only to let them know they aren’t alone. Sunlight exposure can make Lupus worse or be a trigger for some types of vasculitis sores.  The patient forum tips also included a warning not to use petroleum jelly (Vasoline TM) within the nasal passages as it can increase risk for a type of lung infection. Coconut oil was recommended by another forum comment and is the active ingredient in a product that I’ve found helpful for moistening the dry scabby tissue – pain is the common complaint along with bleeding or seeping plasma from the sore tissue. Applying tiny amount within the nasal passage or ear area is not easy but pain is unpleasant. /(After reading the patient forum tips I’ve switched to plain coconut oil as was suggested and it does seem more healing than the thicker chapstick which likely contains some waxes in addition to coconut oil. While a humid, moist air quality is helpful I’ve also found that clean air is important, smoke or smog like air made the skin condition worse whether there was a humidifier or not.)/

I’ve also found relief after a magnesium sulfate/Epsom salt bath and the dryness is reduced with adequate humidity in the air. A damp towel hung near a heating vent can help add humidity to a closed small room if a commercial humidifier isn’t available or seems inadequate. Commercial humidifiers should be cleaned with bleach water or another sanitizing agent occasionally or they may be adding mold or other infectious pathogens to the air – the damp towel dries each night and needs to be remoistened and simply washed occasionally as it doesn’t really get dirty or mold because it doesn’t stay damp. Mold and pathogens can grow on the commercial humidifiers because they tend to always retain some moisture in portions of the machinery. )

Not having a severe headache, migraine pain, and being able to breathe through both nostrils at the same time due to frequent congestion problems are also part of my good days versus bad days. Severe exhaustion and just having the energy to get dressed can be a limiting factor for a day’s goals to get anything else accomplished. Chronic illness is becoming more common rather than less common and how to help prevent or manage it is something that nutrition can help in ways that a bottle of medication can’t because the cell repair throughout the body needs many trace nutrients, vitamins and minerals, and an adequate amount and variety of protein and essential fats and carbohydrates – every day, throughout the day.

Strolling through the distractions used to suggest my concerns about nutrition are unfounded simply reveal the accuracy. (More on the “Weaponization of Social Media” by the U.S. and others) My providing free information is simply in the hope that it might be helpful to someone. I will be fine because I’ve found the research and am using it for my own benefit. Living in a desert is not something that my health can handle however and has never been my goal. The advantage of a virtual world is that if twenty readers find my information valuable then they can benefit from it wherever they are sitting and don’t need me to be present or to be living in a desert area.

Do your own research or find a health care practitioner that is trained in nutrition to help guide you if you are interested in taking better care of yourself now rather than waiting for worse chronic illness or brain degeneration. You could be one of the twenty readers who are interested or not, life is full of choice but consider whether you are choosing for yourself or whether you are accepting society’s Darwin Award of chronic illness via modern lifestyle. The United States is becoming one of the most unhealthy countries on average. Qatar is leading the group too but only since the decades since switching to a modern lifestyle and dietary habits.  (20% diabetes rate in Qatar)(Magnesium deficiency causes insulin resistance)

Supporting big business profit goals is noble but so is survival of the ecosystem over the next thousand years – if we make it through the next one hundred I have hope that we will have figured out more sustainable ways to produce energy and use renewable agricultural methods and that we will survive the next thousand – we are at a turning point where pretending the status quo is working is no longer helpful and is harmful even over the short term.

  1. Obsessive about vitamin D, must be crazy – no my recommendation to not take excessive vitamin D and calcium supplements as it is not a sure way to protect against bone fracture risk and may be harmful, has been since supported by research and is now the standard recommendation. My initial recommendation was in February 2011, this update is December 2017:  https://www.acsh.org/news/2017/12/27/calcium-and-vitamin-d-supplements-still-do-not-prevent-fractures-12329
  2. Some people may truly have low vitamin and hormone D levels while others may have a condition that causes the inactive vitamin D level to be low while the active hormone D level is elevated and likely causing an elevation or tendency to elevation of the body’s calcium levels through increased absorption and decreased excretion and which also leads decreased magnesium absorption and increased magnesium excretion as the minerals are kind of a team. In ancient times magnesium was very plentiful in the water and food supply while calcium is rare so our evolutionary physiology tipped towards conserving calcium and wasting magnesium. Ideally simply ask to have both your inactive vitamin D level (25-D) and your active (1-25-D) hormone D levels to be tested but the current treatment and research recommendations generally just test the less expensive measurement of 25-D. Sarcoidosis, HIV, tuberculosis, Rheumatoid Arthritis are some examples of diseases that may have altered balances of 25-D and 1-25-D. The metabolism of vitamin D is complicated and the commonly used herbicide Roundup which contains glyphosate may be inhibiting the CYP enzymes that are needed to make the active form of hormone D from the inactive form or to make the inactive form with sunshine. This is not a widely accepted theory yet (more on the topic in a previous post) but my own health is better for having reduced my intake of foods that may contain glyphosate and by adding a powdered form of the amino acid glycine to my daily routine. I added the supplemental powder when I had a genetic screening performed that revealed a double gene difference in my ability to digest larger proteins down to the individual glycine. It has active roles within the brain which can help reduce anxiety as well as performing other functions and my health has been much improved. Glyphosate is only one methyl group (-OH, one atom of oxygen and one of hydrogen) different from glycine. (more on glycine & glyphosate in this previous post) Inhibition of CYP enzymes might also increase risk of pancreas problems and diabetes and may play a role in risk of developing autism but it isn’t the only chemical that is likely involved and deficiency of vitamin D is likely not the only nutrient deficiency involved – (more on that in this post.)  By the way, I’m looking for a particular link and just haven’t found it yet – please be patient. Still looking but here is a post with some dietary guidance for prenatal or other people interested in reducing intake of foods that may contain glyphosate: (Self care for prenatal care, part one) Okay I found it, see link [page 19, 1] “Other pathogens that have been shown to reduce the activity of the Vitamin D Receptor, in addition to the pathogen that causes Tuberculosis, include the mold Aspergillus, the viruses that cause Epstein-Barr chronic fatigue syndrome and HIV/AIDS, and the autoimmune diseases sarcoidosis, Crohn’s Disease, and Rheumatoid Arthritis. Elevated levels of 1, 25(OH)2D are seen with the bacterial infections: “Elevated 1,25(OH)2D appears to be evidence of a disabled immune system’s attempt to activate the VDR to combat infection.” [page 19, 1]”  an excerpt from post: [http://transcendingsquare.com/2015/08/11/whether-to-be-compliant-or-to-be-healthy-seems-like-an-easy-question-to-answer/]” which I included in (Preventing autism perinatally – before conception) Newborn umbilical cord samples which are already collected could be tested for more chemicals in order to help identify which infants are likely to be more at risk for developing autism – I would be because of my genetic difference in my ability to digest protein down to the individual amino acid glycine. A researcher found 15 lab test biomarkers/chemicals in common and to save money organized them into three groups – if an infant has the first five, then pay for the screening of the second set of five and if the infant also has those differences then screen for the last set of three chemicals. If all fifteen or most of the fifteen are different than average than the infant may need dietary modifications to help with special methyl forms of B vitamins or supplements of glycine or methionine or help with detoxifying heavy metals for example. See (Newborn Sceening for Autism – 3 sets of 5 potential biomarkers) As an overview and update I will add a link to an article about a recent review of research on the finding that low vitamin D levels are associated with increased risk for many types of cancer – but – excess levels of vitamin D don’t help protect even more than adequate or good levels. Some nutrients and chemicals are safe at elevated levels because they are excreted easily while others are safe and helpful in a -U- shape, too little or too much can be unsafe to health. Vitamin D when activated to the hormone can help control our own immune system’s ability to make antibiotic type chemicals of our own – all day, everyday as long as the nutrient building blocks are available. Too much or too little vitamin/hormone D can increase risk of cancer or of autoimmune disease.
  3. This isn’t about “I told you so” it is about our government or some other agent actively preventing helpful information from being shared. I will keep sharing information that can be helpful because I know how much pain hurts and some chronic degeneration of body and brain function can not be reversed it can only be prevented – seeing your loved ones and having them not remember basic facts about themselves or their family members hurts emotionally – having them forget how to be able to swallow food hurts them physically unless caregivers to spoon feed them can be afforded or are available within the family. You may have to physically massage their throat to help stimulate a swallow reflex, simply putting the spoon in the mouth may not be enough to stimulate a swallow reflex in end stage Alzheimer’s Disease.
  4. Magnesium matters – and Epsom salt baths or foot-soaks (about one cup magnseium sulfate salt to a half bath for 20 minutes every 3 to 4 days or half cup in a tub of water for a 20-40 minute footsoak) can be a better absorbed method – this is now supported by research. It may also help protect against and reverse early stages of Alzheimer’s  Disease. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4182554/
  5. Symptoms of magnesium deficiency can include mood changes such as depression, anxiety, or anger and irritability and physical symptoms such as muscle cramps, eye twitches, or dry eye. https://www.healingtheeye.com/dry_eye.html
  6. Magnesium is nature’s method for blocking calcium channels – and it doesn’t cause the potential side effects that pharmaceuticals may cause (PPIs such as Pprilosec, Nexium and Prevacid.) http://transcendingsquare.com/2015/10/18/magnesium-deficiency-can-cause-irritability-anxiety-and-chronic-degeneration/
  7. Iodine is an essential nutrient for a healthy weight and appetite for adults and infants and moderate deficiency during pregnancy may be an under lying cause of later development of autism. For some reason I can’t imagine the U.S. nutrient database for iodine content was deleted some point in time between when I first started writing about it in 2010/2011 and now. I keep checking in the hope that the information has been restored – but that day isn’t today: https://ndb.nal.usda.gov/ndb/nutrients/index
  8. Zinc, B12 and vitamin D deficiency can mimic symptoms of schizophrenia which is a mental disorder where the brain isn’t recognizing the person’s own subvocal thoughts and mutterings. Treating with psychiatric drugs or only one of the missing nutrients wouldn’t cure the person of the symptoms if multiple nutrient deficiencies were the cause.  Low thyroid levels may also be a risk factor and elevated C-reactive protein or an elevated copper to zinc ratio may also be a factor. http://transcendingsquare.com/2016/03/19/the-voices-that-people-with-schizophrenia-are-hearing-are-probably-their-own-inner-thoughts/
  9. Calcium or vitamin D deficiency can cause hyperparathyroidism which can cause disoriented thinking and may cause self injury or suicidal urges. http://transcendingsquare.com/2016/04/23/self-injurious-behavior-in-autism-patients-with-low-calcium-levels/

That’s the short list.

Calcium and vitamin D supplements are not recommended to help prevent hip fractures

A recent meta-analysis  published in JAMA (2) of research on the efficacy of calcium and vitamin D supplements to help prevent hip fractures and other types of bone fractures in Senior Citizens or post-menopausal women found no benefit compared to placebo or no treatment.  The meta-analysis included 33 clinical trials involving 51,145 participants.

The brief overview article does not mention if harm was found but concludes with the simple statement that the findings do not support a routine recommendation or use of calcium and vitamin D supplements in community dwelling older people. Read more: Thumbs Down on Calcium and Vitamin D to Prevent Hip Fracture (1)

Adequate magnesium in a form the body is able to absorb well, which may require a topical form such as soaking with magnesium sulfate salt (Epsom salt) or magnesium chloride products, is required for maintaining bone health. The minerals silicon and boron are also important and the mineral strontium in microgram amounts may help. Vitamin K from leafy green vegetables and green herbs and spices (or in the form of vitamin K2 supplementally may be helpful) is also important for maintaining bone density. (3)

EMFs and Intracellular Calcium – Magnesium is nature’s calcium channel blocker

Electromagnetic fields, (EMFs) are the non-ionizing radiation that makes WiFi connections work and other devices like televisions and cellphones. The electronic details are beyond my field of experience and they are generally claimed to be harmless however research is being done on the health effects on people and other species. As more and more ‘hotspots’ become active and there is discussion of making entire regions WiFi spots the question of whether the radiation is truly harmless or not is important.

The research that has been performed suggests that the mode of action is on the ion channels in cell membranes called voltage-gated calcium channels (VGCCs). The EMF radiation seems to activate ion channels and allows the interior of the cell to fill with calcium which then can proceed to activate membrane breakdown and other actions within the cell. Oxidative stress can involve an excess of calcium within the interior of the cell which leads to other free radical chemicals – electrically active chemicals which antioxidant nutrients can help deactivate. See: (1)

Oxidation is a normal part of cell function as it is how glucose sugar energy is freed for use. Too many oxidative free radical chemicals also called, reactive oxygen species (ROS), can overpower the natural antioxidant chemical pathways and lead to increased cell damage and even cell death. (2, 3, 4)

Ion channels refer to chemicals that contain atoms that have a positive or negative charge which can be used to provide energy for chemical reactions. Ions in nature generally are found in pairs with a balance of positive and negative charges so the grouping is fairly stable. Calcium and magnesium both have ionic forms with a chemical charge of +2, which means they are missing two electrons. Sodium and potassium have ionic forms with a chemical charge of +1 – they are missing one electron each.

An ion is an atom or chemical that has more protons than electrons and carries a positive charge or has more electrons than protons and carries a negative charge, while a free radical specifically has at least one unpaired electron in its outer electron shell/valence which makes it very reactive but does not necessarily mean an electron is missing nor suggest a negative charge. Depending on their chemistry they may be able to receive or donate another electron and are very reactive, very active chemically, as the outer shell prefers to be stable chemically. The presence of an unpaired electron makes the free radical chemically encouraging other chemicals to give up or receive the unpaired electron even if the other chemical is more chemically stable. (7) The electrons in an atom are arranged around the inner ball of positively charged protons and neutrally charged neutrons in layers of electrons (valences) which prefer to be in groups of 2, 6 or 8 electrons, so a free radical with an outer layer with one electron might want to donate it while one with an outer shell with seven electrons might want to receive an extra electron.  Element valences are slightly different than what might be expected looking at the Table of Elements – here is a chart of the typical ion or free radical charges: (6)

Oxygen can carry an electrically negative charge of -2, meaning it can accept two additional electrons in its outer valence. (6) And hydrogen can accept or donate an electron, +1 or -1, (6) which chemically can result in our most important molecule for life – water, H2O, formed from two atoms of hydrogen sharing their unpaired outer electron with one atom of oxygen which wants an additional two electrons. The slight preference for different electric charges gives the molecule of water a slight polarity, the oxygen part of the water molecule has a slight negative charge on average while the hydrogen parts of the molecule have slight positive charges. (8) A more thorough description of the chemical structure of the water molecule and its electrical charge distribution with illustrations is available here: (12).

Why is this important? Because our bodies are made up of at least 70% water and electromagnetic radiation does have effects on water (9) so a basic understanding of the chemistry can help understand the more complex issues of why having region wide areas of WiFi might affect health of humans and other animals, plants and possibly even microbial life. There is evidence that microbes can modify nearby DNA via EMFs generated by the microbial DNA when both sets of DNA are in a watery dilution. (10, [1602 from ref 9]) This may increase risk of infection or cross contamination of infectious substances. We don’t know what we don’t know. The research may simply confirm the need to be concerned about Electromagnectic fields on DNA. The negative effect of EMF exposure to DNA and an increase in DNA breakdown/fragmentation was mentioned in the first link. See: (1).

Research that looked for epigenetic effects on DNA that might be associated with leukemia or other cancerous changes found that Extremely Low Frequency-Magnetic Fields which have been labeled potentially carcinogenic as some association with leukemia has been noted, did not consistently lead to epigenetic changes in the study. Changes that did occur were more likely to be found when the genetic material, called chromatin, was in a more open and active form rather than when it was in the condensed, non-replicating form. (13) Pregnancy would be a time when DNA is expected to be more active, and infancy and childhood are also times when growth and replication of cells is expected. Concerns and a review of available research about the risk of EMF radiation for adults and childhood development is discussed in a Special Section of the journal Childhood Development: (14)

Calcium channel blocker medications have been found to help reduce the effects of EMF radiation for individuals who seem to be more sensitive to ill effects from the form of radiation than the average person. See: (1)

Magnesium is nature’s calcium channel blocker so there may be an underlying deficiency of magnesium in the the people who are more sensitive to EMFs. A number of conditions can make the intestines absorb less magnesium and more calcium than average and the kidneys can be better at holding onto calcium and more likely to excrete magnesium than average. The food and water supply is not as rich in magnesium as it was during earlier centuries of human development. Magnesium deficiency as a risk factor in sensitivity to EMFs is discussed in the first link and it introduces a protective factor that can be increased with more variety of vegetables and other phytochemical rich foods in the diet – nuclear factor erythroid-2-related factor 2 (Nrf2). See: (1)

Specific foods or phytochemicals mentioned to help increase Nrf2 include:

  • sulforaphane from cruciferous vegetables, (such as broccoli and cauliflower);
  • foods high in phenolic antioxidants, (This is a large group including bright yellow and red fruits and vegetables, and deep purple produce. The group includes the subgroup flavonoids which include anthocyanins, flavonols, and it also includes the less familiar subgroup chalcones which are found in the commonly used fruits apples, pears and strawberries. The group also includes aldehydes which are found in vanilla and cinnamon, phenolic acids which include salicyclic acid, and tannins which are found in tea, coffee and wine. Baking cocoa and cherries, beans and whole grains are also mentioned, the summary point would be eat more fruits and vegetables; see: (11))
  • the long-chained omega-3 fats DHA and EPA, (salmon, tuna, sardines, krill oil, ground flax meal, walnuts, hemp seed kernels);
  • carotenoids (especially lycopene), (such as carrots, winter squash, sweet potatoes, cantaloupe, apricots, and lycopene is in tomato, watermelon, pink grapefruit, guava); 
  • sulfur compounds from allum vegetables, (such as onions, garlic, shallots, green onions); 
  • isothiocyanates from the cabbage group and
  • terpenoid-rich foods. (Terpenes are found in real lemon and lime oil, rosemary, oregano, basil and other aromatic green herbs).
  • The Mediterranean and the traditional Okinawan Diets are also mentioned as being Nrf2 promoting diets. See: (1)

A 2012 article that discusses the science known at the time and reviews cellphone cases designed to redirect EMF radiation away from the user available at the times suggests some health evidence exists but that the information is not conclusive yet but that no study has been longer than ten years. Children have less dense bone structure and may be accumulating more life time exposure so limiting use of cellphones around children or their use by children may be playing it safer until more research is available. (5) Turning off cellphones when not needed can save battery time and would be turning off the WiFi when it is not needed. You can always check for messages when you turn it back on again. Using a hard wired computer at home or at least turning off the laptop at night is recommended along with other tips in the first link. See: (1)
