Formaldehyde: Health risks, and Environmental and Dietary sources.

I mentioned in my last post, (a long time ago – I’ve been busy spring cleaning), that I would discuss oxidative stress next – some background information first:

(“Formaldehyde is a cause of oxidative stress.” LMGTFY: 1,450,000 results.)

Formaldehyde:  formaldehyde is a chemical that can be produced within the body as part of metabolism, it is toxic however and the body would continue to break it down further for removal from the body in conditions of normal health. Formaldehyde is found in the environment from a variety of sources and is produced in the body or in food products as a metabolite (a chemical produced from the digestion/metabolism of a larger chemical) of some alternative sweeteners (G.48) and other dietary sources including fruit juices and artificial and natural flavorings. ((G.49, (p476, G.50)) (G.56)  “Formalin” is chemically very similar and may cause similar health symptoms. (G.42(G.25Formalin is used to induce pain in lab animals for experimental purposes and it was determined that the pain was due to activation of the TRPA1 channels. (G.86)

Environmental and dietary sources of formaldehyde include, (G.56):

  1. First and second hand smoke, (G.44); The formaldehyde content of some types of E-Cigarette preparations used for “vaping” instead of smoking the volatile gases have been found to vary significantly. Skipping to the last point on this list may provide the explanation – fruit flavoring based on fruit juice and essential oils from fruit and other artificial “flavorings” are frequently chemicals from a group of chemicals called aldehydes. They can break down over time into smaller chemicals which can include formaldehyde or other toxic types of aldehydes. (G.49) So if you are “vaping” in order to avoid toxins in cigarette smoke then it may be advisable to skip the “chocolate or fruit flavoring” and use an E-Cigarette product that just has the natural tobacco flavor instead. (Yes, tobacco is an herb and it has a flavor and nicotine can have some health benefits, however formaldehyde does not. The nicotine patch provides a steady dose of nicotine without any volatile toxins.)
  2. Poorly ventilated air or smog; (G.45)
  3. Vinyl and PVC plastic products off-gas formaldehyde and other volatile chemicals at levels that can make a sensitive person feel ill. (G.45). A poorly ventilated room would increase the risk of the gases accumulating to more toxic levels. The wax refinishing treatments used to clean and shine vinyl flooring are also sources of formaldehyde and other toxic gases. One re-waxing session can produce as much volatile chemicals from the chemical products that are used to strip off the old layer of wax polish and add a new layer, as the vinyl floor itself would off-gas throughout all the years of its installation. So making a choice about which type of flooring to install is also making a choice about the  type of cleaning products that will be needed to maintain the floor. (G.46) A Cleaning Product Fact Sheet is available from the California Environmental Protection Agency Air Resources Board: (G.47). Types of flooring and other building materials are discussed in extensive detail in a review article regarding sources of Formaldehyde in the Indoor Environment: (G.45).
  4. Metabolites of the breakdown of the alternative sweetener aspartame and Neotame include menthol and formaldehyde. (G.48)  
  5. Older packages of fruit juice also may contain formaldehyde in amounts that can continue to increase as the product ages. The formaldehyde is produced as other chemicals become unstable over time and metabolically breakdown into a variety of smaller chemicals which include formaldehyde. The food preservative method of ionizing radiation has been found to increase the chemical breakdown of larger aldehydes in apple juice into formaldehyde and other chemicals with toxic properties. (p476, G.50)
  6. Before leaving the topic of formaldehyde, the symptoms of toxicity with workplace exposure to formaldehyde have been reported to include allergic type symptoms including: “sneezing/airways-related symptoms, itching and watery eyes.” (G.51) Formaldehyde exposure may also be a cause of systemic allergic contact dermatitis, (G.52, G.53, G.54), possibly even with symptoms of rash occurring on the eyelids.(G.55) A diet designed to avoid formaldehyde intake may be helpful for alleviating the eczema like rash. (G.52)

A summary, in reverse order;

Formaldehyde might be accumulating from several sources, (G.56):

  • Workplace exposure; Workers more at risk might include health professionals, (G.51); and hair stylists or nail salon technicians, (G.58); and funeral directors may be more at risk for developing the paralyzing chronic disease ALS, (G.59); some industries such as the garment and textile industry may have formaldehyde exposure, (G.63);
  • Aseptically packaged juices, the amount may collect in older packages as the product ages, ionizing radiation methods of food preservation have been found to increase the amount of toxic aldehydes including formaldehyde and therefore is not a recommended technique for the juice industry, (p476, G.50);
  • Nutrasweet (aspartame) and Neotame, alternative sweeteners. (G..48)
  • Vinyl flooring, cleaning products, and other PVC type of plastic products. (G.45, G.46, G.47);
  • Poorly ventilated air or smog. (G.45); *Note, lighting large numbers of decorative candles may be increasing volatile chemicals in your air supply. Also air fresheners and cleaning products may contain chemicals that break down into formaldehyde. (G.60) Lifestyle choices besides smoking cigarettes can negatively affect health. Try a fern for air freshening instead; give it a nickname and you might get some emotional benefits in addition to other physical health benefits. Plants can be useful household decorations because some types can clean the air of formaldehyde and other toxins. The original research was by a NASA scientist for use in keeping the air fresh in living environments for astronauts. For the most effective air cleaning ability, the plant does need to be watered and misted as its particular type requires, because the chemical removal of formaldehyde from the air is dependent on the roots and leaves access to water. (G.61); a mechanical problem with the furnace or water heater and ventilation system may be leaking toxic chemicals into the building’s air supply; increased efficiency of insulation and other building materials have created rooms and buildings that are too good at preventing air circulation, which makes maintenance and cleaning of ventilation systems and fans important – otherwise everyone working or living in the space might start feeling some symptoms of “sick building syndrome.” (G.62)
  • Smoking cigarettes or other products, and flavorings in “vaped” E-Cigarettes may also be a source of formaldehyde. (G.44, G.49)

Fact Sheets regarding Formaldehyde, Environmental Safety and Health:

  • The Centers for Disease Control provides a fact sheet for further guidance regarding risks and precautions regarding formaldehyde: What You Should Know About Formaldehyde, (G.57)
  • The Environmental Protection Agency provides a fact sheet on sick building syndrome: Fact Sheet: Sick Building Syndrome, (G.62)
  • The Cleaning Products Fact Sheet, by the California Environmental Protection Agency’s Air Resources Board provides guidance regarding safer cleaning products: (G.47)
  • The National Cancer Institute’s Fact Sheet: Formaldehyde and Cancer Risk includes research on occupations that may be at risk for formaldehyde exposure and provides a list of organizations that might have more information or other help to offer. (G.63)

Sick Building Syndrome: Symptoms that may occur due to breathing air that contains too much formaldehyde may include sore throat, cough, scratchy eyes, and nosebleeds according to the fact sheet by the Centers for Disease Control. (G.57) So if everyone working in a building, or many workers or family members are all experiencing allergies or a slight cold that just doesn’t seem to want to go away – then bad air may be a problem. See the fact sheet on Sick Building Syndrome by the EPA for more information. (G.62)

Eczema: The eczema symptoms reported in medical research may occur with more chronic long-term exposure to formaldehyde and/or in individuals who also have more difficulties metabolically with detoxifiying formaldehyde – we don’t know all the answers. I have personally experienced skin rashes off and on all my life and was startled to develop it on my eyelids in my more recent past – and then was more startled, or more relieved to learn of the possible cause – formaldehyde exposure (G.55) and systemic allergic contact dermatitis, (G.52, G.53, G.54) Poor air quality was a problem at the time in part due to water heater mechanical problems, and also first and secondhand smoke were contaminants in my air supply – I cleaned up and changed habits somewhat and my eyelid rash got better – yeah science! To me that seems like an example of effective self care and effective use of evidence-based medical research even if I had to read it on my own.

Other health risks include cancer and neurological conditions: The link between cancer and formaldehyde may be less strong than for neurological disorders such as ALS in funeral home directors, (G.59), or autism in a child whose mother had prenatal exposure to formaldehyde, (G.56), however research has found some cancers associated with occupational exposure to formaldehyde. The National Cancer Institute also has a fact sheet on the topic of formaldehyde and it includes a convenient list of addresses and websites for organizations that might have more information for workers concerned about exposure risks such as OSHA, the Occupational Safety and Health Administration,. (G.64) See the National Cancer Institute’s Fact Sheet: Formaldehyde and Cancer Risk for more information and resources regarding formaldehyde and occupational safety: (G.63)

Houseplants can help offices as well as astronauts:

If you are looking for a hair salon that is likely to have less formaldehyde and other volatile toxins in the air then look for one with lots of healthy ferns and other tropical low light houseplants. (G.61) If you are a hair salon or other business owner interested in improving the air quality in your establishment with the help of ferns and other houseplants, then hire a staff member who knows and loves plants because they do require some consistent care that can vary quite a bit depending on the type of plant – or buy the book by the NASA research scientist and have an employee learn how to care for your indoor air-cleaning garden.

The scientist, B. C. Wolverton, organized what he learned to help astronauts in an easy to use plant guide that lists the species of plants which were found most effective at cleaning air. The book, How to Grow Fresh Air: 50 Houseplants that Purify Your Home or Office, includes guidance for caring for each species and also lists them by the types of volatile chemicals that they were able to remove from the air. (G.66)

Large urban areas may have office plant services available where a greenhouse or florist shop supplies and maintains lovely office plants for a subscription or rental type of payment. An employee of the plant business has a route of subscribing businesses to visit each week in order to water, mist, and trim plants of any dead leaves, even a healthy plant will look sad if it is covered in a layer of dust and has a few dead leaves. Plants that are sick are simply returned to the greenhouse for care or recycling and the empty spot is filled with a replacement by the plant business employee.

Ambius is an example of an office-plant company with service locations available in many urban areas in both Canada and the United States. See the Ambius website for more information and service locations:

The herbicide Round-Up found more dangerous than Glyphosate alone

The herbicide Round-Up contains glyphosate which is considered the active ingredient but research suggests that the supposedly inert ingredients in the mixed product make Round-Up as much as 125 times more dangerous to health than glyphosate alone. An international society for science has assembled a review of literature on the topic within the following article:

Round-Up ready crops have been found to require more water and do less well in drought situations than normal crops. Pigs fed GMO based foods were found to become significantly healthier when the farmer switched to non GMO based feed for them.

Glyphosate residues have been found to drop after individuals switched to a diet based on non GMO, organic foods and autism symptoms were found to improve for individuals who were switched to a non GMO organic food diet. Single case studies may be considered anecdotal and not worth considered but each and every patient is a single case study for themselves.

How many people need to get sick in the U.S. before we decide that we would rather not be experimented on by agribusiness and the processed food industry?

Excerpts from the article:

Glyphosate widespread in the environment and in our bodies

“Due to the official ‘safe’ status of glyphosate, data on how much we are being exposed have been scarce, forcing citizen activists and civil society organizations to find out for themselves. Friends of the Earth Europe commissioned an analysis of 182 volunteers across 18 EU countries and found detectable levels in 44 % of urine samples [13] with concentrations ranging from 0.16 ug/L average in Switzerland, to 1.82ug/L in Latvia. Of the UK citizens tested, 7 out of 10 were positive. In the US, urine samples show concentrations 8 times those in Europe [13]. The analysis, commissioned by Moms Across America, also tested 10 mother’s breast milk, which came up positive for glyphosate with levels ranging from 76 µg/L to 166 µg/L (76-166 ppb) (see [14]). These levels are 760 to 1600 times higher than the European Drinking Water Directive allows for individual pesticides, and raise obvious concerns as they fall within the range of concentrations at which developmental toxicity has been observed in animal studies (see below). This analysis is the only study on breast milk to date, as no government or public health body has found it necessary to carry out any study on bioaccumulation in internal organs and tissues or in breast milk fed to infants.”

Health of American citizens deteriorating

“One argument for the safety of GM food and their associated pesticides is that the US has been consuming them for years without ill effect. However, in the absence of labelling GM foods, it is illegitimate to make such a claim. On the contrary, there has been a drastic deterioration of public health in the US since GM crops were introduced. A new publication by Swanson and colleagues plots the rise of 20 chronic diseases using available US government data, all correlating closely with increasing glyphosate application to corn and soy crops, especially over the past several years. The diseases included cancers, Parkinson’s, autism, obesity, diabetes, heart disease, digestive disease and kidney failure [62]. Correlation does not prove causation, but such strong association certainly cannot be dismissed, especially in combination with the plethora of other evidence from laboratory studies, and the experiences of doctors in their clinics and farmers in the fields. For a detailed analysis of the study please see [67] Marked Deterioration of Public Health Parallels Increase in GM Crops and Glyphosate Use, US Government Data Show ( SiS 65).”

Glycine is an amino acid with neurotransmitter roles

Subtitle: Rebranding and the power of a name: “Essence of Meat-ade” or “Cheerful Juice.”

Sub-subtitle:  Genetic defects in metabolism can affect the entire body due to lack of essential nutrients.

Background: I was found to have eleven of thirty defects in the methylation cycle that were known to be more common in patients with autism spectrum disorder. The screening is not for diagnostic purposes at this stage but is available to consumers interested in the information for their own research purposes (which might include what to feed their child or themselves for better management of autism symptoms – but it is use at your own risk information rather than ‘evidence based’ medical treatment approved for a certain diagnosis).

One of my genetic defects affects my ability to break down betaine into the free amino acids glycine and methionine (roughly, I would have to review the chemistry for the specifics). So armed with this new information I ordered tablets of each amino acid and started taking them each day as supplements. They seemed to help but it wasn’t a dramatic change in how I felt.

A month or two later before reordering more bottles I considered the question of just how much glycine or methionine I might need each day if I had a defect that prevented me from digesting protein and releasing the essential amino acids. When I looked into how much glycine might be needed by the body each day, I didn’t find much research but there was some and the amount suggested was far greater than the amount I was taking in the form of a tablet — 200 milligram tablet compared to two grams of the essential amino acid as a minimum recommendation with up to ten grams being proposed as possibly beneficial. And no toxicity risks were mentioned. Two grams is equivalent to 2000 milligrams or ten of the tablets each day, which would be expensive and a lot of tablets.

Many things that are available as supplements are also available in bulk as a powder that companies might use to make capsules or tablets for the individual consumer to purchase. The amino acids glycine and methionine were available online in a package size that was designed for individual use, possibly being marketed to people interested in body building or weight lifting.

A teaspoon of a powder substance is roughly five grams, depending on the density of the powder. I decided to try one teaspoon of glycine and one teaspoon of methionine per day as that would easily provide two grams and might provide up to five grams per day.

Results: Free essential amino acids are acidic — like lemonade — but taste a little like protein aka meat, so two teaspoons of free amino acids in water tasted VERY BAD. My nickname for the concoction became “Essence of Meat-ade” for the first day or two, however almost immediately after drinking the vile drink my mood became incredibly cheerful and I was suddenly filled with energy. I was amazed — how could a horrible tasting glass of water change my mood? I started looking forward to the drink and while I had started taking it in the evening I gradually switched to taking it earlier in the day and even twice a day occasionally, which would provide about ten grams of the powder.

My mental nickname changed from “Essence of Meat-ade” to “Cheerful Juice,” it helped my mood so much that I loved the stuff no matter how silly my face looked while trying to gulp it down too quickly to taste. I was amazed, and a little sad to consider that I had been without “Cheerful Juice” for my first fifty years of life — but better late than never is a motto of mine. With a double genetic defect I wouldn’t have been able to release glycine or methionine from larger proteins for my entire life — and therefore wouldn’t have had the cheerful effects or boost in energy due to the incomplete digestion of my food.

Why would a bad tasting drink give me a good mood?

I knew the amino acids glutamine and aspartic acid can act as messenger chemicals within the brain so I looked up glycine and methionine and sure enough they both also can act as brain signaling chemicals.

The rest of this information is about glycine’s role as a brain neurotransmitter. It doesn’t cover methionine but it also has roles in brain chemistry.

Glycine is a Neurotransmitter: 

Glycine has inhibitory and excitatory roles in the brain as a neurotransmitter – a type of chemical that can serve as a messenger between brain cells which are called neurons.

“Interestingly, glycine receptors comprised of a1 subunits are efficiently gated by taurine and b-alanine, whereas a2-containing receptors are not (8). The a1 and a2 genes are expressed in the adult and neonatal brain, respectively.”

ie-the type of glycine receptor found within the baby brain is not as well protected as the type found within the adult brain, later in the next paragraph:

“Recently, the expression of a1 and a2 subunits has been shown to be developmentally regulated with a switch from the neonatal a2 subunit (strychnine-insensitive) to the adult a1 form (strychnine-sensitive) at about 2 weeks postnatally in the mouse (8). The timing of this “switch” corresponds with the development of spasticity in the mutant spastic mouse (5), prompting speculation that insufficient expression of the adult isoform may underlie some forms of spasticity.” [1]

Background: Glyphosate is chemically very similar to glycine in that it may be incorporated into proteins but is not functionally the same. A protein containing glyphosate instead of glycine would be dysfunctional. Glycine provides methyl groups which are important for turning strands of DNA on and off, (DNA is the genetic material that acts as recipe cards for making proteins).

If glyphosate is being physically incorporated within body tissues in place of the amino acid glycine, then the role of glycine within early fetal development discussed in the above excerpt might be part of the mechanism for how autism risk may be occurring during the prenatal stage of life.

From a Marketing Perspective: How to sell something that tastes horrible but makes certain people feel great?

From my experience working with special need infants and children I learned that sick children when given a formula they can tolerate will cheerfully start drinking the formula if it  isn’t making them feel sicker — no matter how bad the formula tastes — and some of them are like “Essence of Meat” because they are based on free amino acids that would be easy to digest and wouldn’t have the same allergy risk as the larger and more complex proteins.

So how to market a specialty product? Target the special needs market, and pitch having the genetic screening done first in order to find out who needs the special product — and put the bulk powder in capsules  😉 , I tried to add lemon flavoring to make it more like lemonade but that didn’t change the flavor enough — I’m working on acquiring a taste for it instead.

The genetic screening I had done is “For Research Purposes Only” but it was assembled by a specialist with a PhD and experience in genetics. She is not a medical doctor and no diagnoses are provided however some health information is provided I haven’t reviewed it yet and therefore can not provide any feedback regarding it.

  • The Methylation Cycle genetic screening test:
  • My results and my notes regarding the 11 defects, this is a list of notes rather than being in article format, see number three of the double defects for details about the gene BHMT/1 (Call – T), which is for the enzyme Betaine-homocysteine methyltransferase (BHMT):
  • An excerpt from that post regarding diagnoses that may be helped by use of dimethylglycine (DMG) and methionine as supplements : DMG has been found helpful in ADHD, autism, allergies, alcoholism, drug addiction, and chronic fatigue syndrome among other chronic issues. Methionine has been found helpful in treating depression, allergies, alcoholism and schizophrenia among other chronic issues.
