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

Relieve Hip Pain After Sitting or Driving

Posted June 20, 2017 by Dr. Steve Chaney

Relief is Just a Few Movements Away!

Author: Julie Donnelly, LMT – The Pain Relief Expert

Editor: Dr. Steve Chaney

 

relieve hip pain after sittingI’m on a long business trip, speaking and teaching in Tennessee and New York, and the drive from Sarasota, FL meant many hours of driving over several days.  One of my stops was to visit with Suzanne and Dr. Steve Chaney at their home in North Carolina.  It was that long drive that became the inspiration for this blog.

After all those hours of driving, my hip was really sore. It was painful to stand up. While talking to Suzanne and Dr. Chaney I was using my elbow to work on the sore area, and when we were discussing the blog for this month it only made sense to share this technique with you.  So, Dr. Chaney took pictures and I sat at his computer to write.  I thought others may want to how to relieve hip pain after sitting or driving for long periods.

What Causes Anterior Hip Pain?

As I’ve mentioned in posts in the past, sitting is the #1 cause of low back pain, and it also causes anterior hip pain (pain localized towards the front of the hip) because the muscles (psoas and iliacus) pass through the hip and insert into the tendons that then insert into the top of the thigh bone.  When hip pain reliefyou try to stand up, the tight muscle tendons will pull on your thigh bone.  The other thing that happens is the point where the muscle merges into the tendon will be very tight and tender to touch. You aren’t having pain at your hip or thigh bone, but at the muscular point where the muscle and tendon merge.

It’s a bit confusing to describe, but you’ll find it if you sit down and put your fingers onto the tip of your pelvis, then just slide your fingers down toward your thigh and out about 2”. The point is right along the crease where your leg meets your trunk.

The muscle you are treating is the Rectus Femoris, where it merges from the tendon into the muscle fibers.  Follow this link, thigh muscle, to see the muscle and it will be a bit easier to visualize.

You need to be pressing deeply into the muscle, like you’re trying to press the bone and the muscle just happens to be in the way.  Move your fingers around a bit and you’ll find it.

Easy Treatment for Anterior Hip Pain After Sitting

relieve hip painHere is an easy treatment for hip pain after sitting you can administer yourself.  First, sit as I am, with your leg out and slightly turned.

Find the tender point with your fingers and then put your elbow into it as shown.

It’s important to have your arm opened so the point of your elbow is on top of the spasm.  It’s a bit tricky, but if you move about a bit you’ll come on to it, and it will hurt.  Keep the pressure so it’s tolerable, not excruciating.

After you have worked on this point for a few minutes you can move to the second part of the treatment.

hip pain treatmentPut the heel of your “same-side” hand onto your thigh as close to the spasm as you can get.  Lift up your fingers so the pressure is only on the heel of your hand.  You can use your opposite hand to help give more pressure.

Press down hard and deeply slide down the muscle, going toward your knee.  You can also kneed it like you would kneed bread dough, really forcing the muscle fibers to relax.

I’m putting in a picture from a previous blog to explain how you can also treat this point of your rectus femoris by using a ball on the floor.

As shown in this picture, lie on the floor with the ball on your hip muscle, and then slightly turn your body toward the floor so the ball rolls toward the front of your body. You may need to move the ball down an inch or so to get to your Rectus Femoris.

When you feel the pain, you’re on the muscle.  Just stay there for a minute or so, and if you want you can move so the ball goes along the muscle fibers all the way to your knee.

pain free living book coverIt may be a challenge to find this point, but it’s well-worth the effort!

In my book, Treat Yourself to Pain Free Living, I teach how to treat all the muscles that cause pain from your head to your feet.

Wishing you well,
