Do Your Supplements Contain Carcinogens?

Author: Dr. Stephen Chaney

 

pahs in supplementsMost of us take supplements to improve our health. We count on those supplements being pure and effective. We don’t expect the supplements we take to contain carcinogenic (cancer causing) contaminants. However, that expectation appears to be unfounded. A recent study found that 72% of supplements tested were contaminated with a particularly dangerous class of cancer causing chemicals called polycyclic aromatic hydrocarbons (PAHs)

Where Do PAHs Come From  andWhy Are TheyDeadly?

Polycyclic aromatic hydrocarbons (PAHs) are produced by incomplete combustion of organic materials. Major environmental sources of PAHs are incomplete burning of gasoline, coal and other fuels. Unfortunately, automobile exhaust, coal burning power plants, and exhaust from factories are almost ubiquitous in today’s world, resulting in significant PAH contamination of our air, water, and soil. The unfortunate truth is that we all live in an increasingly dirty and toxic environment.

pahs can come from highwayAs you might imagine, cigarette smoke is the #1 source of PAHs in humans. However, foods are a major route for PAH exposure in humans as well. There are many food sources of PAHs. For example,

  • Grilling, roasting and frying foods, especially meats, at high temperatures creates PAHs.
  • Smoking fish or meats creates PAHs.
  • Barbecuing meats creates PAHs.
  • Even plant-based foods can contain PAHs if the soil, air or water they were grown in was contaminated.
  • PAHs can be introduced into supplements if any of their ingredients are dried at high temperatures as part of the processing procedure.

By now you are probably realizing that it is not just our environment that is increasingly being contaminated with PAHs. We are all becoming contaminated with PAHs as well. Our bodies are becoming toxic waste dumps.

Unfortunately, PAHs are not innocuous chemicals. Perhaps the best studied and deadliest of the PAHs is a compound called benzo[a]pyrene. It is classified as a class 1 carcinogen and mutagen by the IARC (International Agency for Research on Cancer). Perhaps some explanation is in order:

  • The IARC is an international organization that is charged with evaluating the scientific evidence for the carcinogenicity of various chemicals. It also sets upper limits for safe exposure to those chemicals.
  • Class 1 carcinogens are compounds that the IARC has classified as definitely carcinogenic to humans. Simply put, the IARC considers the scientific evidence to be overwhelming that those compounds are carcinogens.

To date only 118 compounds have been blacklisted by the IARC as class 1 carcinogens and benzo[a]pyrene is one of them. However, many of the other, less studied, PAHs are classified as probable carcinogens by the IARC.

Unfortunately, in most countries of the world (including the United States), PAH limits in food and supplements are unregulated. Because they are unregulated, many supplement companies don’t even test for them. That is unfortunate because a recent study shows that many supplements are contaminated with high levels of PAHs, and their manufacturers didn’t even know it.

Do Your Supplements Contain PAHs or Other Carcinogens?

carcinogens in supplementsThe European Union has taken the lead in regulating PAH levels. They have used the IARC guidelines to create upper allowable limits for PAHs in food and supplements. Separate standards were set for benzo[a]pyrene and the total of the four most common PAH contaminants (benzo[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthrene, and chrysene). Those new regulations just went into effect April 1st 2016.

To gauge the impact of these new regulations on the supplement industry, the EU asked the European Union Reference Laboratory to measure the levels of PAH contamination in supplements sold in the EU prior to the implementation of the new regulations. Because vitamin and mineral supplements are seldom contaminated with PAHs, they were excluded from the study.

The EU Reference Laboratory started collecting a wide range of herbal and botanical supplements, fish and edible oil food supplements, and propolis and other bee supplements sold in the EU in 2013. The Reference Laboratory analyzed 94 different supplements for PAH contamination, and the results of these analyses were published in October 2015 (Z. Zelinkova and T. Wenzyl, Food Additives & Contaminants: Part A, 32: 1914-1926, 2015).

[In case you, like me, were wondering what propolis is, it is a resin like substance that bees use as a glue to hold their hives together. WebMD states that it may have some use as a topical agent for cold sores, genital herpes, and after mouth surgery, but that any other uses are unproven. However, if you visit websites for propolis products you find it in capsules and liquids for internal consumption. You are told that it cures bacterial and fungal infections, cures viral infections like AIDs, cures cancer, and removes warts.]

The results of their analysis were pretty scary:

  • 72% of the supplements tested exceeded EU limits for the four most common PAH contaminants, and 52% exceeded EU limits for benzo[a]pyrene.
  • Propolis and spirulina were the most heavily contaminated supplements. Valerian and St. John’s Wort had moderately high levels of contamination, and some samples of bee pollen, sea buckthorn oil, barley greens, Echinacea, and Ginko far exceeded EU standards.
  • If consumers took the recommended dosage of the two most contaminated products (Premium Spirulina and Propolis Intense) they would more than double their daily intake of PAHs and far exceed what the IARC considers safe.
  • Fish oils generally had low levels of PAH contamination. The authors speculated this may be because fish have the ability to metabolize PAHs. However, other edible oils, particularly sea buckthorn oil and a mixture of garlic oil with soybean and sunflower oils did exhibit significant PAH contamination. The authors speculated that this PAH contamination may have been introduced during the processing of these oils.

Why The PAH and Contamination Problem Is Worse Than You Thought

worseYou might be thinking what could be worse than 72% of supplements being contaminated with cancer causing PAHs? Here is some food for thought.

  • PAHs are just the tip of the iceberg. Many supplements are also contaminated with PCBs and heavy metals. For example:
  • Fish oil is often contaminated PCBs.
  • Rice protein and other rice-derived ingredients are often contaminated with lead and/or mercury.
  • The US regulates PAHs in our water supply, but does not currently regulate PAHs in our supplements. That means that manufacturers that make products primarily for consumption in the US have no incentive to test their products for PAH contamination. Most of them have no idea whether their products are safe or not.
  • There is no guarantee that even products labeled Certified Organic and Non-GMO are free of PAH contamination. For example:
  • Organic certification just means that the crop was raised using organic methods. No analysis of purity is required to assure that the crop had not been inadvertently contaminated. The same is true of non-GMO certification. No analysis of purity is required.
  • Organically grown, non-GMOcrops that are used as ingredients for supplements can still be contaminated if the air, soil or water is contaminated from any nearby pollution source. For example, ground water pollution is the major source of the heavy metal contamination often seen in rice-derived ingredients.
  • Organically grown, non-GMO crops can even become contaminated by PAHs if they are grown next to a busy highway.
  • Even if the ingredients are pure to begin with, PAH contamination can be introduced during processing.

What does all of this mean to us? It means that it is absolutely imperative that we do our due diligence and only choose supplement manufacturers whose quality control standards far exceed what is required of the industry. Our health just may depend on it.

 

The Bottom Line

 

  • A recent study has reported that 72% of herbal and botanical supplements, fish and edible oil food supplements, and supplements derived from bees sold in the EU were contaminated with high levels of cancer causing polycyclic aromatic hydrocarbons (PAHs).
  • The levels of PAHs in many of these products far exceeded standards recently enacted by the EU. If those supplements were taken as recommended, the daily intake of PAHs by people consuming them would also far exceed the safe limits of exposure to these toxic chemicals set in place by the International Agency for Research on Cancer.
  • While all of this sounds bad enough, the news is even worse for most of us living in the US.
  • PAHs are just the tip of the iceberg. Many supplements are also contaminated with PCBs and heavy metals.
  • The US regulates PAHs in our water supply, but does not currently regulate PAHs in our supplements. That means that manufacturers that make products primarily for consumption in the US have no incentive to test their products for PAH contamination. Most of them have no idea whether their products are safe or not.
  • There is no guarantee that even products labeled Certified Organic and Non-GMO are free of PAH contamination.
  • What does all of this mean to us? It means that it is absolutely imperative that we do our due diligence and only choose supplements manufacturers whose quality control standards far exceed what is required of the industry. Our health just may depend on it.  Remember, PAHs are not the only potential problem.

One of the Little known Causes of Headaches

Posted August 15, 2017 by Dr. Steve Chaney

Your Sleeping Position May Be Causing Your Headaches!

Author: Julie Donnelly, LMT – The Pain Relief Expert

Can sleeping position be one of the causes of headaches?  

A Sleeping position that has your head tilted puts pressure on your spinal cord and will cause headaches. I’ve seen it happen hundreds of times, and the reasoning is so logical it’s easy to understand.

causes of headachesYour spinal cord runs from your brain, through each of your vertebrae, down your arms and legs. Nerves pass out of the vertebrae and go to every cell in your body, including each of your organs. When you are sleeping it is important to keep your head, neck, and spine in a horizontal plane so you aren’t straining the muscles that insert into your vertebrae.

The graphic above is a close-up of your skull and the cervical (neck) vertebrae. Your nerves are shown in yellow, and your artery is shown in red.  Consider what happens if you hold your head to one side for hours. You can notice that the nerves and artery will likely be press upon. Also, since your spinal cord comes down the inside of the vertebrae, it will also be impinged.

In 2004 the Archives of Internal Medicine published an article stating that 1 out of 13 people have morning headaches. It’s interesting to note that the article never mentions the spinal cord being impinged by the vertebrae. That’s a major oversight!

Muscles merge into tendons, and the tendons insert into the bone.  As you stayed in the tilted position for hours, the muscles actually shortened to the new length.  Then you try to turn over, but the short muscles are holding your cervical vertebrae tightly, and they can’t lengthen.

The weight of your head pulls on the vertebrae, putting even more pressure on your spinal cord and nerves.  Plus, the tight muscles are pulling on the bones, causing pain on the bone.

Your Pillow is Involved in Your Sleeping Position and the Causes of  Headaches

The analogy I always use is; just as pulling your hair hurts your scalp, the muscle pulling on the tendons hurts the bone where it inserts.  In this case it is your neck muscles putting a strain on your cervical bones.  For example, if you sleep on your left side and your pillow is too thick, your head will be tilted up toward the ceiling. This position tightens the muscles on the right side of your neck.

Dozing off while sitting in a car waiting for someone to arrive, or while working for hours at your desk can also horizontal line sleepcause headaches. The pictures above show a strain on the neck when you fall asleep without any support on your neck. Both of these people will wake up with a headache, and with stiffness in their neck.

The best sleeping position to prevent headaches is to have your pillow adjusted so your head, neck, and spine are in a horizontal line. Play with your pillows, putting two thin pillows into one case if necessary. If your pillow is too thick try to open up a corner and pull out some of the stuffing.

If you sleep on your back and have your head on the mattress, your spine is straight. All you need is a little neck pillow for support, and a pillow under your knees.

Stomach sleeping is the worst sleeping position for not only headaches, but so many other aches and pains. It’s a tough habit to break, but it can be done. This sleeping position deserves its own blog, which I will do in the future.

 

Treating the Muscles That Cause Headaches

sleeping position causes of headachesAll of the muscles that originate or insert into your cervical vertebrae, and many that insert into your shoulder and upper back, need to be treated.  The treatments are all taught in Treat Yourself to Pain Free Living, in the neck and shoulder chapters.  Here is one treatment that will help you get relief.

Take either a tennis ball or the Perfect Ball (which really is Perfect because it has a solid center and soft outside) and press into your shoulder as shown.  You are treating a muscle called Levator Scapulae which pulls your cervical vertebrae out of alignment when it is tight.

Hold the press for about 30 seconds, release, and then press again.

Your pillow is a key to neck pain and headaches caused by your sleeping position.  It’s worth the time and energy to investigate how you sleep and correct your pillow.  I believe this blog will help you find the solution and will insure you have restful sleep each night.

Wishing you well,
