Protecting Yourself From Environmental Toxins

Environmental toxins are toxins that may be in your drinking water, in what you eat, in the air you breathe, or they enter your body through your skin when you swim in contaminated water or walk on a sandy, wet beach.

In the following blog I will address some of these issues and how we can defend ourselves against toxins.

The youngest and most vulnerable

Toxins are particularly bad for infants and premature babies.

The reasons for this are the following ones: their kidney function (tubular secretion) is only 20% to 30% of that of an adult; the cytochrome P-450 enzyme system in the liver, one of the toxin eliminators is slowed down to only 25% to 50% of the adult activity and glucuronidation in the liver, another detoxification process, reaches adult levels only at the age of 3 years. The kidneys and the liver are limiting the removal of toxins by way of urine and bile in the newborn. Stomach acidity in a premature has a pH of 4.7, in a full-term newborn 2.3–3.6 and in an adult 1.4–2.0. This is important to note as a lack of stomach acid increases susceptibility of newborns and infants to gastrointestinal infections and cause diarrhea. Percutaneous absorption in newborns is much higher than in adults, which makes them very susceptible to absorbing toxins through the skin (Ref.1).

Diabetes from environmental toxins

Environmental toxins can cause insulin resistance and type 2 diabetes.

Bisphenol A (BPA) is used to make polycarbonate and epoxy resins and is found primarily in food and beverage containers. The world population has been exposed to this since 1957 and as a result 90% of US residents have detectable levels of BPA in their urine. Ref.2 explains that the higher the urine concentration of BPA, the higher the risk is for developing diabetes.

Persistent organic pollutants are another source of concern: pesticides and herbicides, dioxins, polychlorinated biphenyls, hexachlorobenzene, and hexachlorocyclohexane have all been found in humans. Several investigators have shown that virtually all of the risk in obese patients to develop diabetes comes from the fat-soluble persistent organic pollutants (Ref.2).

Inorganic arsenic is another pollutant that is found in soil and rock naturally and finds its way into the drinking water. About 8% of the public water system of the US exceeds 10 mcg/L for drinking water, which has been set as the safe limit for drinking water by the US Environmental Protection Agency’s standard. Anything above those levels is considered toxic.Ref.2 describes that people who ingest inorganic arsenic will excrete it in the urine; the highest group with arsenic in their urine had a risk of 3.58-fold to develop diabetes when compared to the lowest group. Curiously enough organic arsenic that is found in fish and shellfish is excreted in the urine unchanged and does not cause diabetes. Overall this indicates to me that nobody should consume or cook with contaminated water that contains inorganic arsenic. Reverse osmosis filters will protect you from this risk.

Other toxins around the house

Volatile organic compounds are often contained in carpets, but also in laser and inkjet printers. They are part of everyone’s life as this link shows. Varied symptoms like irritation of eyes, nose or throat, breathing problems, headaches, loss of coordination, damage to the liver, kidneys and the brain have been reported after exposure to volatile organic compounds. Long-term exposure can even cause cancer in animals and has been suspected to cause cancer in humans as well.

Air fresheners and cleaning solutions that contain ethylene-based glycol ethers and terpenes have been the subject of a study that examined concentrations in the air and interaction with ozone that can also be released by some cleaners. As this link shows the investigators concluded that with exposure to high enough concentrations and long enough exposures to these fumes lung cancer can be caused in cleaning personnel. They recommended to use cleaning solutions only in diluted form and to air out the premises well after cleaning. Another component of many air fresheners and cleaning chemicals is paradichlorobenzene, the same chemical that is contained in mothballs.

There have been problems with flame retardants: polybrominated diphenyl ethers, which are cancer producing; they have been outlawed in the US since 2004, but older mattresses, upholstery, television, computer casings and circuit boards may still contain them.

Lead and mercury poisoning, and radioactive pollutants

Manufacturers were not allowed to use lead in paints anymore since 1978. Paint from buildings older than that still may contain lead. There have been serious lead poisonings in children who were gnawing on items painted with lead containing paint. Lead causes problems with your central nervous system, brain, blood cells and kidneys. Just last year a news story about lead found in fashion jewelry surfaced warning about cheap fashion jewelry from China. Lead form these items can be absorbed through the skin and cause lead poisoning. Because of the apparent lack of regulations in China it is my recommendation not to buy anything that goes into your mouth or on your skin, if it has been grown or produced in China.

Mercury from tuna and other predator fish: It is sad that the oceans are polluted to the point where it has become unsafe to eat predator fish as there is an accumulation of mercury through the food chain.

How did things develop this way? Back 100 years and more ago gold panning and the purification process of gold caused mercury to enter into rivers and allow mercury to end up in the oceans where it has since accumulated; it just sits there as it has nowhere to go.

Coal burning (yes, there is mercury in coal) has also contributed to this by smoke being emitted from smoke stacks containing mercury vapors, which ended up returning to earth as polluted rain and drained through the river system into the oceans.

It is monomethylmercury that accumulates in the tissue of humans. It affects many organs, such as the brain, kidneys, lungs, and skin. It causes various symptoms like red cheeks, fingers, and toes; there can be bleeding from the mouth and ears; it can cause rapid heartbeats, high blood pressure, intense sweating, loss of hair, teeth, and nails. It also can cause blindness, loss of hearing, impaired memory, and lack of coordination, disturbed speech and birth defects. You may think all mercury comes from the outside. However, silver amalgam fillings in your teeth could also be the source of mercury poisoning. It is a good idea to replace amalgam/mercury fillings with ceramic fillings.

There are many forms of other marine pollution as this link shows.

One particular concerning aspect is pollution with radioactive materials as the Fukushima disaster in Japan has shown. Following the catastrophe on March 11, 2011 there have been several leaks of radioactive material into the ocean, which are described here. Dr. John Apsley II pointed out that with the explosions in Fukushima there were also several releases of radioactive pollution into the stratosphere. This pollution has subsequently traveled around the globe and has come down as radioactive rain. He has made it his ambition to help people minimize radiation exposure from nuclear accidents such as Fukushima.

Protecting yourself from toxins

Having said that pollution and toxins are problems that we are living with, how can we protect ourselves from all of that?

1. Avoid as many unsafe chemicals around you as you can. This includes checking ingredients in hair care and body care products, toothpaste, hair dyes, cosmetics, mouthwashes and underarm deodorants.  I have written a blog about toxins in the bathroom and what you should watch for.

2. I would recommend you switch from a standard food to organic food. It has become unsafe to eat non-organic meats, leafy vegetables, vegetables and fruit. There are too many residues of herbicides and pesticides contained also in meat, not only in vegetables and fruit. Washing will not remove these substances, even though some merchants may tell you otherwise. Buyer beware!

3. Detoxification methods are available and I have reviewed them in this blog. Briefly, to remove lead and mercury a formal intravenous chelation protocol should be followed.  Depending on how many heavy metal toxins you have on board, you may need only a few treatments or else up to 20. Here is a more conservative website stating that it would be safe to have silver amalgam fillings. I think that gold and ceramic fillings are much safer.

4. Genetically modified food is another danger as I have summarized in this blog. This is another reason why I like to stick to organic food. There is evidence that GMO food causes autoimmune diseases, infertility and chronic inflammation that can eventually lead to cancer. It may take decades to prove this, but I am not willing to be a human guinea pig.

5. I have mentioned in a prior blog that we live in a toxic world. You need to carefully look at your home and remove toxins. You need to assess your drinking water. A water analysis can tell you how good the water in your home is and whether there are concerns about inorganic arsenic. Usually places that sell filter systems can advise you in that regard. Your drinking water should either be bottled pure water or else reverse osmosis water that can be part of a filter system in your house.

6.Vitamins and supplements have been shown to support your cell integrity and have anti-inflammatory and antioxidant effects that protect you from toxins. I discussed this in detail in my NetHealthBook under nutrition. For instance vitamin D3 in doses of 5000 IU or more and CoQ-10 are powerful anti-inflammatories and CoQ-10 is also an antioxidant and preserves mitochondrial function. High fish oil supplements (3 to 6 Grams per day) have anti-inflammatory effects and protect your cell membrane integrity. With these overlapping qualities of vitamins and supplements your body will be in a much stronger position to defend itself against the negative effects of toxins. When you take multivitamins, this translates into telomere lengthening of 5.1% (or converted into a survival advantage of 9.8 years when it is accumulated over a life time). Ref. 4 explains this in more detail.

7. Exposure to radioactive substances is a scary thought, but this is becoming more and more a reality, at least for those who live close to disaster areas such as the Fukushima site in Japan or the Chernobyl site in the Ukraine. But according to Dr. Apsley II low dose radiation that we have already received in the US and in Canada following the Fukushima disaster is equally disastrous (Ref.3). Many of the vitamins and supplements I have mentioned are also cell and mitochondria protective and will help with DNA repair following radiation damage, but you must avoid sugar and other refined carbs and starches to reduce the oxidative effect on cells and on LDL cholesterol to prevent premature aging and cell death. Ref. 3 contains a lot more detail about this and explains what specific supplements can be taken to detoxify your system from specific radioactive elements that function as free radicals. There are specific antidotes for radioactive iodine-129 and iodine-131, radioactive cesium-137 and others.


Many people shrug their shoulders when they hear that pollution has an effect on their lives. They feel that they are powerless and cannot do anything about this. The truth is far from this! Above I mentioned seven points that you can follow to counter toxins. On top of that you can get politically active and urge your government representative to create a nuclear free zone in your area. Ref. 3 contains compelling evidence why this is so important not only for us now, but for future generations and the future of mankind. We need to hold those who provide us with food and beverages accountable for the quality of these. Shrugging it off is not good enough. Get involved. Buy organic food. Avoid the section in the grocery store where sugar and high carb foods are sold. It’s good for your own health, but it will collectively change the mentality of the grocery store owners who will notice that they are stuck with the comfort foods that sold well in the past. This new trend will result in cheaper prices for healthy foods and more availability of organic food.

Peanut Allergies Are Deadly

In the US 1.5 million suffer from peanut allergies (Ref.1). People who have peanut allergies have to avoid peanuts and foods that contain even traces of peanuts lifelong. Here is a recent example of a 13-year old girl who died at a camp when she tried food contaminated with peanuts. Before we discuss peanut allergies in detail, we need to review first how the immune system is functioning.

How the immune system is primed to develop an allergy

Our immune system knows the difference between our own body components and substances that come from the outside. Scientists call this tolerance to our own surface proteins; and scientists call it an immune reaction that is mounting as a reaction to anything different from the surface antigens. There are different cells that make up the immune system. One of the main working cells of the immune system are the lymphocytes, with B cells originating from the bone marrow producing antibodies when an immune reaction occurs. Antibodies fit like a lock and key to the surface of an antigen, in this case the peanut protein. T helper cells are T lymphocytes (thymus derived lymphocytes) that help the B cells to recognize the difference between the own protein components and the outside components. There are also T killer cells, which get activated when parasites or viruses enter the body. With regard to peanut allergies it is the B cells and T helper cells that interact and the B cells produce a powerful, very specific IgE antibody directed against peanut protein. There are memory B cells, which continue to produce these specific anti-peanut protein antibodies and cause severe allergic reactions when future exposure to peanuts (even traces) occurs. So, the more often a person who is allergic to peanuts encounters even traces of peanuts, the immune system will get boosted and produce even more antibodies of the IgE type through reactivated B memory cells (Ref. 2). 98% of the population does not react to peanut exposure with allergies, but the other 2% who may have genetic susceptibility factors that predispose them to this often develop life-threatening reactions (an anaphylactic reaction).

What is an anaphylactic reaction to peanuts?

The most extreme form of allergies involving IgE antibodies can cause anaphylaxis. In the beginning stages of a peanut allergy there may only mild symptoms such as hives on the skin, itching and tingling around the mouth, a runny nose, a scratchy throat, wheezing, stomach cramps, vomiting or diarrhea. However, with a more severe allergy an asthma attack can develop, blood pressure drops leading to fainting or shock and severe airway obstruction in the throat or lungs can cause suffocation.

I vividly remember an 11-year-old boy who was brought in by ambulance to the emergency room of the hospital where I was working as the on-call physician. He had a hard time talking as his throat was swelling up as part of his anaphylactic reaction, within minutes he passed out completely (shock). Fortunately an anesthetist was in the department and could intubate him very quickly. However, despite adrenaline treatment, oxygen  by artificial ventilation and high doses of corticosteroid drugs he did not wake up until 10 hours later. In retrospect it turned out that he had eaten some crackers of a familiar brand that he knew as being free of peanut flour. However, he had seen an ad that the same brand of crackers was available as cheese crackers and he tried one of these, which prompted his admission to the hospital. The parents read the ingredients later: the label on the cheese crackers noted in small print that the flour of the cheese crackers contained peanut flour! Always read labels, even if it is a familiar brand! Fortunately for this boy he did not have brain damage from the time of his unconsciousness. He has been extremely careful since and is reading labels and avoiding unknown food items.

Cross-reactions between peanuts and other allergens

Allergies can be made worse when a person has inhalant allergies from pollens of trees or grasses that can share protein components from protein found in foods. The latest findings are that there are cross allergies between Fenugreek and lupine, which are both legumes, as are peanuts, so there are common antigens present in their proteins. A mouse-testing model has shed more light on this. Fenugreek has been shown to control mild diabetes by improving insulin resistance, but it cannot be consumed by persons who are highly allergic to peanuts because of the cross allergy mentioned.

There are other possible cross allergies to legumes like lentils, soy and chickpeas.

Other factors that can cause allergies to get worse

In the past the RAST test was often used.  This is a blood test for common food allergies that can cause severe allergic reactions like egg, milk, peanut, tree nuts, wheat, crustacean shellfish and soy. However, since about 2010 this has been replaced by the more sensitive ImmunoCAP Specific IgE test. Children who have food allergies to egg, milk, wheat, nuts, peanuts and soy often outgrow these allergies when they age, in other words their immune system can develop tolerance to many of these foods. Not so with peanut allergies ! They tend to be very persistent.

The immune responses to food allergies are complicated as there are immediate type immune reactions and delayed type immune reactions. The immediate immune responses are investigated with the above mentioned ImmunoCAP Specific IgE test. The delayed immune responses can be measured using the ELISA test. Positive IgE antibody tests for peanut protein are a marker that the person affected likely has more other allergies and they should be investigated by a knowledgeable allergist in that regard (Ref. 2).

What complicates the allergy sufferers’ lives even more is the fact that new wheat varieties since the 1970’s, called Clearfield wheat have a much higher gliadin (gluten) and lectin content than the old wheat varieties. As a result of exposure to this new type of wheat gluten intolerance and leaky gut syndrome have increased substantially in the world population (Ref.3). In addition, genetically modified foods like soy, corn, sugar beets, canola and others have challenged the immune system of sensitive humans even more. We do know that some people can develop autoimmune diseases from GMO foods and modern wheat, and this may be the reason that a host of diseases that belong into this disease category (MS, rheumatoid arthritis, Hashimoto’s thyroiditis, ankylosing spondylitis etc.) are much more common now than in the past. The geneticists who developed GMO foods seemed to be unaware how sensitive the immune system is, which will detect a few different amino acid sequences in a protein mounting a strong immune response to it.

Treatment for peanut allergies

The key for sufferers from peanut allergies is to avoid exposure to it. Read labels and use common sense. If something is not labeled, do not be tempted to eat it. Peanut flour is often mixed into the dough of crackers, not being labeled properly or only in fine print. With peanuts the antibodies usually circulate in the blood life long as the B memory cells do not diminish and get reactivated very quickly on repeat exposure producing antibodies again. As exposure to peanuts can cause severe asthma or anaphylactic shock, it is important to carry an EpiPen with you and to know how to use it.

In Europe attempts have been made to develop an oral desensitization method for food allergies including peanut allergies, but it has not produced concrete results yet. Recently, however, research from Texas, USA showed that it is possible to desensitize patients with peanut allergy by oral desensitization. In Australia where food allergies are more prevalent than in the US, tolerance to peanut, nut and shellfish allergies is being pursued by oral immunotherapy. Another group in Australia has developed a vaccination method using peptides, which are a sequence of amino acids, but shorter than the full peanut protein. It appears that this is the future direction of  treatment for peanut and other IgE mediated allergies: a kind of vaccination treatment to induce competing antibodies, which will neutralize the allergic IgE antibodies.


Peanut allergies have become more troublesome as the food industry has mixed peanut flour into Thai sauces, drinks, cookies, crackers and such. The person allergic to peanuts must read food labels and eat as much single-ingredient natural food as possible. This goes against the tendency of food processors who produce foods with a long rat tale of ingredients. If you see a label “may contain nuts or peanuts”, stay away from this product, as it is safer. Always carry an EpiPen or Twinject with you, just in case you develop an anaphylactic reaction (you only have a few minutes to stop the allergic reaction with adrenaline). In the future vaccination with a peanut protein specific peptide vaccine as mentioned regarding the Australian research, will probably become the treatment of choice.

Getting Ready For Ragweed Allergies Is Important

Allergies are often associated with watery eyes and sneezing, and in commercials that promote over-the counter anti-allergy pills (antihistamines) the effects are shown as merely bothersome. The commercials are often amusing. The facts for the allergy sufferer are neither amusing nor are allergies a minor bother. They have to be taken serious, as they can affect the quality of life and even be potentially life threatening. A very common plant that can be the culprit for serious allergies is ragweed. Two varieties of the plant are accounting for the worst problems, Ambrosia trifida and Ambrosia artemisiifolia. People who are sensitized to the pollen of ragweed have the most severe symptoms in the months of August to October. Nasal congestion, sneezing, a constantly runny nose and itchiness of eyes, nose and throat are the problems that are encountered by the patient, but asthma can be the more serious consequence. The quality of life in the peak season of ragweed shows significant deterioration for allergy sufferers, as nasal congestion alone is linked to poor sleep quality which in turn leads to decreased productivity at work or in school. A skin rash can be another form of an allergic reaction. It is the less common form of ragweed allergy, but left untreated it becomes chronic and progressively worse. Other herbal products (chamomile and arnica), which may be used as compresses and as an ontment, can cross-react with ragweed exposure and produce a skin rash or dermatitis. Adults are more affected than children, and people with outdoor occupation (farmers, gardeners, harvesters, carpenters) are the group most at risk. Unfortunately, ragweed particles are very small and very light, which makes it very difficult to avoid them in the peak season, but there are measures one can take to avoid exposure.

Getting Ready For Ragweed Allergies Is Important

The peak time of pollen exposure is in the middle of the day, and it is a good idea to keep the windows closed to prevent large amounts of pollen from drifting into your home. The use of an air conditioner in the car or at home can be helpful. After spending time outdoors it can be helpful to change into fresh clothes and perhaps even take a shower. Drying clothes on the laundry line in peak season should be avoided, as they are prone to collect large amounts of pollen.

Ragweed Blossoms Late In The Season

Timing vacations to leave ragweed-infested areas for other parts of the country can also help. It is also important to take action as soon as symptoms are present. Letting things take their course, will just have a snowball effect. An allergist can do patch tests to determine whether there is a reaction to ragweed. If ragweed dermatitis is present, it has to be treated early on to avoid the difficult to treat chronic state, in which a lower UV threshold is also part of the condition. Decongestants may help with nasal congestion, but unfortunately they tend to cause side effects, such as sleeplessness and a rapid heart beat. The physician can point out the most effective antihistamine to the patient, and intranasal cortico steroids (INCS) may be preferable over oral antihistamines. Newer INCS medications have shown to provide quick control of nasal symptoms, and they can actually minimize the emergence of symptoms, if they are started before the ragweed season begins in mid summer.
