Do They “Cherry Pick” Scientific Studies?

Author: Dr. Stephen Chaney

cherry picking studiesWhen we buy a food supplement from a company we assume that it will provide a benefit. We are trusting that company to be honest in their product claims. But, are there any honest nutritional supplement companies?

  • What if they were lying to us?
  • What if they had no clinical studies done with their product?
  • What if they were just quoting studies done with ingredients found in their product?
  • What if they were “cherry picking” the studies they listed to support the claims they wanted to make?

Unfortunately, that happens far too often in the nutraceutical industry. As an example, I came across an article in a recent issue of www.nutraingredients.com about a FDA warning letter (http://www.fda.gov/ICECI/EnforcementActions/WarningLetters/2016/ucm518533.htm) to a noni juice company.  In case you are wondering, noni fruit is the latest in a long line of “magical fruits” that is going to cure everything that ails you.

The thing that brought this company to the FDA’s attention in the first place was the health claims the company made on their website. The company claimed or implied that their product would cure cancer, cure gout, cure arthritis, lower cholesterol, and help fight infections. Claims like that always invite FDA scrutiny.

What caught my attention, however, was the quote by an attorney specializing in FDA compliance issues that the studies cited on their website were “cherry picked” to support their claims. He said that the studies they cited “…do not meet the standards of third party literature…You have to include a full range [of published studies], and not just cherry pick the positive studies. It has to be a balanced presentation. It looks like they just did a literature search on noni and included only the positive studies.”

That statement caught my attention because it doesn’t just apply to just this one company. It is a practice that is common in the nutraceutical industry.  Many supplement companies cherry pick studies from third party literature. They list only the studies that support their product claims and ignore the rest. That is misleading because it implies a level of proof for their product claims that does not exist.  It is fundamentally dishonest. These are certainly not honest nutritional supplement companies.

Using Borrowed Science

I call this “borrowed science” because the studies were not actually done with their products. They were simply trying to “borrow” results done with individual ingredients and pretend that they applied them to their product.

Let me be clear. Third party studies done with ingredients found in a company’s product are of little value in predicting whether that product will provide any benefit to you. To claim otherwise is dishonest.  Again, these are not honest nutritional supplement companies.

There are several reasons this is true.

  • In many cases, the amount of that ingredient provided by the supplement does not match the amount actually used in the clinical study they quote. The ingredient may or may not be effective at the dose provided in the supplement.
  • More importantly, a supplement usually contains multiple other components that may influence how a single ingredient works in your body. The other components may enhance the effectiveness of the ingredient in question, or they may inhibit it.
  • Without clinical trials done with their product, companies actually have no idea whether their product works or not.

Unfortunately, I see this practice all too frequently in the nutraceutical industry. Clinical trials are expensive. It’s cheaper and easier to search the literature for published studies you can “borrow” to support your product.

 

Honest Nutritional Supplement Companies Do Not“Cherry Pick” Studies

dishonest supplement companiesEven worse, many companies cherry pick studies from the literature to support the product claims they want to make.

To understand what that statement means you need to know a little bit about the scientific method. Most scientists design their experiments to disprove what other scientists have published. This is a self-correcting process that is a strength of the scientific method.

However, it also means that you will find articles in the literature supporting and refuting the benefits of almost every nutraceutical ingredient. The scientific community waits until enough studies have accumulated and then relies on the weight of evidence before drawing any conclusions.

Unfortunately, unscrupulous supplement companies decide first on what claims they want to make and quote only the studies that support those claims. This is what is referred to as “cherry picking” the studies.

The Dietary Supplement Health and Education Act of 1994 (otherwise known as DSHEA) is very clear about that. Section 5 of DSHEA states “…scientific journal articles, books and other publications can be used in the sale of dietary supplements provided…[they] are presented with other materials to create a balanced view of the scientific information…”

In plain words this legalese simply means that you can’t cherry pick studies. You can’t select only the studies that support your product claims and ignore those that don’t.  Honest nutritional supplement companies would not use these deceitful practices.

However, this is a practice that I see all too often in the nutraceutical industry. It is dishonest. It is disgraceful

 

Are There Any Honest Nutritional Supplement Companies?

The bad news is that there are lots of supplement companies that do no clinical studies of their own. Instead they rely on borrowed science from studies that really do not provide proof that their products are either safe or effective. Even worse, many of those companies cherry pick only the studies that support their product claims and ignore studies that do not. This is a practice I regard as clearly dishonest. Those are companies I would avoid.

The good news is that there are a few companies that actually support clinical studies on their key products and publish those studies in peer reviewed scientific journals. Those are companies worthy of your consideration.

There are other things to take into account in selecting the best of the best – things like the number of studies and the quality of the studies. However, that’s a topic for another day.

 

Many Blogs Cherry Pick As Well

deceitful supplement companiesI can’t leave this topic without pointing out that many popular health and nutrition blogs, including those written by some well-known doctors, do exactly the same thing.

The pressures that lead to this behavior are obvious. The very popularity of these blogs depends on them being sensational week after week.

Unfortunately, true science is rarely sensational. It’s usually pretty wishy-washy. If you do a complete search of the literature, you usually find articles that are both for and against any point of view you wish to express. Occasionally, enough evidence accumulates on one side of an issue that scientists are willing to come to a definitive conclusion, but that conclusion is hardly ever sensational.

The only way that the authors of these popular blogs can make sensational claims each week is to cherry pick only the studies that support their point of view and ignore everything else.

Unfortunately, the average reader doesn’t realize this. They see the list of references supporting the claims and believe what they read. Then these bizarre claims get reposted over and over until the general public actually starts believing that they are true.

It really is a shame that DSHEA doesn’t apply to blogs. If it did, they wouldn’t be nearly as sensational, but they would be much more accurate. They would have to report on the whole body of scientific literature, rather than cherry picking just the studies that support their point of view.

In conclusion, there are some honest nutritional supplement companies, but be sure the company you choose to believe is citing studies on their actual products and not just ingredients in their products.  Also, watch out for “cherry picking.”

 

The Bottom Line

 

  • The FDA recently sent a warning letter to a noni juice company for making unsupported health claims for their product. The company was claiming their product could cure things like cancer, gout and arthritis. Whenever a company makes claims like that, they can expect to draw the attention of the FDA.
  • An outside attorney specializing in FDA compliance pointed out that the company also had no good evidence to support their product claims. The company had done no clinical studies on the products. Instead they had “borrowed” the results of third party studies done with ingredients found in their product. Even worse, they had cherry picked only the studies that supported their product claims and ignored the studies that did not.
  • Third party studies done with ingredients found in a company’s product are often worthless in predicting whether that product will provide any benefit to you. I discuss the reasons for that in the article above.
  • Cherry picking only the studies that support a company’s product claims runs afoul of the Dietary Supplement Health and Education Act of 1994 (DSHEA) requirement that companies provide a balanced view of the scientific literature relating to their products. It is also misleading and dishonest.
  • Unfortunately, the practice of using “borrowed science” from third party studies and cherry picking only the studies that support their product claims is common in the nutraceutical industry. Supplement companies that rely on this kind of evidence to support their product claims are dishonest and should be avoided.
  • For products you can trust, choose companies that support clinical studies on their key products and published those studies in peer-reviewed journals. You should also look at the number and quality of studies, but that is a topic for another day.

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

Editor: Dr. Steve Chaney

 

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,

Julie Donnelly
