Every once in a while, a scientific study revolutionizes the practice of medicine and transforms how we lead our lives. The study showing that folic acid supplementation reduced the risk of neural tube defects in newborns was such a study.

First a little history: Dr. Richard Smithells and his colleague Elizabeth Hibbard first started to suspect that folic acid deficiencies were linked to neural tube defects such as spina bifida in the early 60s. By the early 70’s there was enough circumstantial evidence for this link that most doctors were recommending pregnant women start on a prenatal supplement containing folic acid once their pregnancy was confirmed by the obstetrician.

That was when Dr. Smithells convinced the Medical Research Council (MRC) of England to conduct a major, multi-center trial to definitively test his hypothesis. The MRC study (MRC Vitamin Study Research Group, Lancet 338: 131–137, 1991) was terminated in 1991 when it became clear that it was unethical to continue withholding folic acid from the placebo group. The study clearly showed:

  • Folic acid supplementation reduced the incidence of neural tube defects in newborns by 72%.
  • Supplementation with folic acid must start prior to conception for maximum efficacy. If women waited until their pregnancy was confirmed by their doctor, the benefits of folic acid supplementation were much weaker. By then, as the old saying goes: “The horse was already out of the barn”.
  • Subsequent studies have shown that folic acid supplementation is effective at reducing neural tube defects even when the mother and/or baby have MTHFR deficiencies.

As I mentioned before, this study revolutionized medicine and public health in this country.

  • The U. S. Public Health Service and CDC changed their recommendation to “All women of childbearing age should consume at least 400 micrograms of folic acid daily to prevent neural tube defects.
  • Starting in 1998, the United States and Canada mandated folic acid fortification of all flour, enriched pasta, and cornmeal.

 

What About Congenital Heart Defects Prevention?

 

folic acid congenital heart defectsWith the clear success of folic acid reducing the risk of neural tube defects, it was natural to ask whether folic acid supplementation might also help with congenital heart defects prevention. Heart defects affect 1% of all newborn babies. While they can often be treated with surgery, that is horribly expensive and not always successful.

As with neural tube defects, previous clinical studies have provided clear evidence that supplementation with at least 400 mcg/day of folic acid reduces the risk of heart defects in newborns. A meta-analysis of 18 clinical studies estimates the risk-reduction at 28% (Scientific Reports, 5: 8506, DOI: 10.1038/srep08506 ).

The authors of this study (Liu et al, Circulation 134: 647-655, 2016 ) set out to determine whether folic acid fortification had significantly reduced newborn heart defects in Canada. They utilized a database of the Canadian Institute for Health Information that covered 98% of births and stillbirths between 1990 and 2011.

Did folic acid supplementation aid in congenital heart defects prevention?

Of the 5,901,701 births and stillbirths in this database, 72,591 were diagnosed with some type of heart defect. The investigators then compared the prevalence of heart defects before and after 1998 to determine the effect of folic acid fortification on heart defects.

 

Does Folic Acid Aid in Congenital Heart Defects Prevention?

 

folic acid fortifiedThe results of the study were clear cut. Folic acid fortification of flour:

  • Reduced heart outflow abnormalities by 27%.
  • Reduced narrowing of the aorta by 23%.
  • Reduced holes in the heart wall separating the chambers by 15%.

Some types of heart defects were not significantly affected by folic acid fortification, so the overall reduction in newborns with heart defects was 11%.

The paper concluded “Although food fortification with folic acid was aimed primarily at reducing neural tube defects, this population based intervention may also have had a beneficial effect on specific types of [heart defects], which in aggregate are more common.”

Overall, folic acid fortification (providing an extra 100 mcg/day folic acid) did not appear to be as effective as supplementation with 400 mcg/day folic acid at reducing total heart defects in newborns. Perhaps because of that, the senior investigator in the study was quoted as saying “Women who are likely to get pregnant should start taking folic acid supplements before getting pregnant as they may not necessarily receive adequate folate from diet alone.”

 

Does Methyl Folate Aid in Congenital Heart Defects Prevention as Well?

methyl folate mythMethyl folate is being widely promoted as safer, more natural, better absorbed, and more effective than folic acid. I have thoroughly debunked the first three claims in my video “The Truth About Methyl Folate.

What about the claim that methyl folate is more effective than folic acid?

The fact is we don’t even know whether methyl folate is even as effective as folic acid. The studies on neural tube defects and heart defects were done with folic acid, not methyl folate. There are literally thousands of studies on the health benefits of folic acid. Almost all of them were done with folic acid, not methyl folate. It is reasonable to assume that methyl folate might be as beneficial as folic acid, but without clinical studies we simply don’t know.

The few clinical studies that have used methyl folate have not included patients that were given folic acid instead of methyl folate. Without that kind of direct comparison, it is impossible to know whether methyl folate is less effective, the same, or more effective than folic acid.

Finally, there is the claim that methyl folate is more effective than folic acid in people with MTHFR deficiencies. Until we start seeing clinical studies directly comparing the effect of methyl folate and folic acid supplementation on health outcomes in people with MTHFR deficiencies, it is impossible to verify that claim. Once again, methyl folate might be less effective, the same, or more effective than folic acid. We simply don’t know.

Folic Acid does aid in congenital heart defects prevention and methyl folate may.

 

The Bottom Line

 

  • It has been clearly established that folic acid supplementation reduces the risk of neural tube defects in newborns, and that food fortification with folic acid has also helped reduce the incidence of neural tube defects.
  • Previous studies have also shown that folic acid supplementation reduces the risk of heart defects in newborns.
  • A recent study has shown that food fortification with folic acid also contributes to a reduction in the risk of giving birth to babies with heart defects.
  • The U. S. Public Health Service and CDC recommend “All women of childbearing age should consume at least 400 micrograms of folic acid daily to prevent neural tube defects.” Based on the latest studies, folic acid aids in congenital heart defects prevention as well.
  • The studies on neural tube defects and heart defects were done with folic acid, not methyl folate. It is reasonable to assume that methyl folate might be as beneficial as folic acid, but without clinical studies we simply don’t know whether it is even as effective as folic acid.
  • As for other claims about methyl folate, there are no clinical studies I am aware of directly comparing methyl folate and folic acid. Without that kind of study, it is impossible to know whether methyl folate is less effective, the same, or more effective than folic acid.

    No mention here of the 4 possible MTHFR mutations that I understand is present in 30 – 40% of the population. People with this mutation do not adequately process folic acid into methyl folate. For the most affected taking folic acid can be harmful. This can contribute to heart disease and play a role addiction behaviors and heart disease and bipolar disease.

      Dear Robin,

      Unfortunately, there is no evidence to back up your statements. I have addressed this in detail in my video “The Truth About Methyl Folate”

    Dr. Chaney,
    I like what you have to say. You are very sincere and scientific and do not prey on the ignorance of most people. I like the fact that your articles are short, not too technical, and not full of promises. I also like the summary at the end of each article.
    Can you address the issue of clean water and whether or not to add minerals to distilled or purified water? If you have already addressed this issue please send me a link.
    Thank you and God bless your work,
    Jeanne Dart

Stress and Jaw Pain

Get Rid Of Jaw Pain Forever

Author: Julie Donnelly, LMT – The Pain Relief Expert

Editor: Dr. Steve Chaney

 

In this article we will show a connection between stress and jaw pain. 

stress and jaw painStress is a part of everyone’s life, but the way you handle it makes a huge difference.  People think of stress coming from challenges like divorce, bills, etc., but it can also come from happy situations. Positive life changes such as getting married or having a baby can also cause stress.

For some people, the solution to stress is to take a yoga class or practice tai chi regularly.  For others, running, exercising, or listening to music eases their mind.

In my Muscular Therapy office, people frequently tell me “I hold my stress in my shoulders,” or “…in my back.” However, a common stress reaction is to clench your teeth tightly. Actually, people hold stress all over their body, from headaches and clenched jaws to foot pain. I want to discuss how clenching your jaws is a common cause of TMJ. Fortunately, it’s a condition that is easy to treat by yourself.

Stress And Jaw Pain

jaw painJaw pain is commonly caused by a shortening of the masseter muscle. The masseter muscle (circled on graphic) is the muscle that contracts to enable you to chew your food.  Normally, as you chew the muscle shortens and then lengthens as you put more food into your mouth.  How can stress and jaw pain be related?  If you are under stress and your teeth are clenched, you miss the lengthening movement. This imbalance causes the muscle to shorten.

Put your fingers on your cheeks so you are pressing into your back teeth.  Now, clench your teeth and you’ll feel the muscle bulge.  If you clench your teeth when you sleep or you tend to clench your teeth when you are upset, you are setting yourself up for TMJ.

Stress And Jaw Pain (TMJ)

TMJ (Temporomandibular Joint) pain is a condition where your jaw bone rubs or “clicks” over the bone that is just in front of your ear. It is painful, and over time it will damage the bones. When you are under stress and clenching your teeth, you are shortening your masseter muscle. A phenomenon called “muscle memory” will cause the muscle to actually get stuck in the shortened position. The now-shorter muscle prevents you from opening your jaw completely.  For example, when you yawn.  As you are trying to yawn, your jaw flips over the bone and it hurts.

Several years ago, I had a client who had such tight masseter muscles that a dental surgeon was going to sever them so she could open her mouth.  This is a terrible solution because it would mean her mouth would hang open for the rest of her life. Fortunately for this client, she had to get medical approval before she could have the surgery.  When Dr. Cohen (the doctor I worked with) felt her masseter muscles, he refused to sign the permission form. He told her that she had to see me first.  Fortunately, I was there at the time.  It took just 30 minutes for me to release the spasms and teach her how to do the treatment.  At the end of the session she was pressing into both masseter muscles and opening her mouth.  She did it easily and without pain!  She started to cry because she came within one day of having this unnecessary surgery.

Her life was changed by just a simple self-treatment!

Self-Treatment For TMJ Pain

stress and jaw pain reliefHere is how to administer TMJ pain relief to yourself.  Place your fingers as shown in the picture to the left.  Clench your teeth so you can feel the muscles bulge.

Apply deep pressure on just one side for 5 seconds. Then release that pressure and apply deep pressure to the opposite side for 5 seconds. Go back and forth until it doesn’t hurt anymore.  Then find a different “hot spot,” and repeat.  Continue doing this until you can’t find any more tender points on your muscle and jaw.

To stretch the masseter muscle, just press deeply into the original point on the muscle pain free living book coverand slowly open your mouth wide.

Hopefully, you can now see the connection between stress and jaw pain.  Stress is a killer, and is the cause for pain all over your body.  It’s also important to find the cause of stress and do all that is necessary to resolve it.

My book, “Treat Yourself to Pain-Free Living,” will show you how to self-treat painful spasms throughout your body.  Don’t let the pain caused by stress stop you in your tracks. You can become pain-free, and then go and enjoy a yoga class to release stress from your life.

Wishing you well,

Julie Donnelly
