Should Pregnant Women Take Omega-3 Supplements?

Long chain omega-3 fatty acids, especially DHA, have been shown to be very important during pregnancy, especially during the third trimester when DHA accumulates in the fetal brain at a very high rate. It is during that third trimester that the fetus forms the majority of brain cells that they will have for an entire lifetime.

Inadequate intake of long chain omega-3 during pregnancy and lactation has been shown to be associated with poor neurodevelopmental outcomes. These include poor developmental milestones, problem solving, language development and increased hyperactivity in the children (Coletta et al, Reviews in Obstetrics & Gynecology, 3, 163-171, 2010).

  • The Current Recommendation is 200 mg DHA/day During Pregnancy & Lactation.

In order to support brain development in the fetus, some experts have recommend intake of 300 mg per day of DHA during pregnancy. The best dietary sources of long chain omega-3 fatty acids such as DHA are fish and fish oil supplements. However, because of concerns about seafood contamination with heavy metals and PCBs (both of which are neurotoxins), the FDA recommended in 2004 that pregnant women limit seafood consumption to two servings a week, which amounts to about 200 mg/day of DHA – and this has been subsequently adopted by the American College of Obstetricians and Gynecologists and the European Union as the amount of DHA recommended during pregnancy and lactation (Coletta et al, Reviews in Obstetrics & Gynecology, 3, 163-171, 2010).

Even that recommendation for DHA from seafood could be overly generous. A recent study using the EPA risk assessment protocol concluded that some farmed salmon were so contaminated with PCBs that they should be eaten no more than once a year (Hites et al, Science, 303: 226-229, 2004).

  • Most Pregnant & Lactating Women In The US Are Probably Not Getting The Recommended Amount of DHA In Their Diet

Many pregnant women avoid seafood because of concerns about mercury and PCBs. Unfortunately, the other food sources of omega-3 fatty acids in the American diet, even many omega-3 fortified foods and supplements, are primarily composed of the short chain omega-3 fatty acid linolenic acid (also called alpha-linolenic acid or ALA), and only 1-4% of linolenic acid is converted to DHA in the body (Coletta et al, Reviews in Obstetrics & Gynecology, 3, 163-171, 2010).

Consequently, experts have been concerned for some time that American and Canadian women may not be getting enough DHA during pregnancy and lactation, but it was not clear how serious an issue this was.

Do Women Get Enough Omega-3 During Pregnancy?

women take enough dha omega-3 during pregnancyA group of scientists decided to test the adequacy of DHA intake by comparing DHA intake with the recommended 200 mg/day in a group of 600 pregnant and lactating women enrolled in the Alberta Pregnancy Outcomes and Nutrition study (Jia et al, Applied Physiology, Nutrition & Metabolism, 40: 1-8, 2015). The average age of the women in this study was 31.6. They were primarily Caucasian and married. 92% of them breastfed their infants. Most of them were taking a multivitamin or prenatal supplement on a daily basis. Approximately 1/3 of them were also taking a long chain omega-3 supplement.

The majority of women had completed college and had annual household incomes in excess of $100,000/year. In short, this was a very affluent, well-educated group of women. This is the kind of group one might consider most likely to be getting enough DHA from their diet.

DHA intake was based on 24 hour food recalls and supplement intake questionnaires collected in face-to-face interviews 2-3 times during pregnancy and again 3 months after delivery. The DHA content of the diet was determined from these data using well established methods.

The results were both dramatic and concerning.

  • Only 27% of pregnant women and only 25% of postpartum women who were breastfeeding met the recommendation of 200 mg of DHA/day. In short, nearly three-quarters of the women in the study were not getting enough (DHA) omega-3 during pregnancy and lactation.
  • When the women who were taking DHA-containing supplements were excluded from the data analysis, only 13% of pregnant and lactating women were getting enough DHA from their diet. In short, nearly 90% of the women relying on diet alone were not getting enough DHA.
  • Taking a DHA-containing supplement increased the likelihood of achieving the recommended 200 mg DHA/day by 10.6 fold during pregnancy and 11.1 fold during breastfeeding.
  • Not surprisingly, seafood, fish and seaweed products were the major contributors to the total dietary DHA intake.

The authors concluded “Our results suggest that the majority of participants in the cohort were not meeting the EU recommendations for DHA during pregnancy and lactation, but taking a supplement significantly improved the likelihood that they would meet the recommendations.”

 

The Bottom Line

  • Long chain omega-3 fatty acids, especially DHA, are essential for normal brain development. Inadequate DHA intake during pregnancy and lactation is associated with poor developmental milestones, problem solving, language development and increased hyperactivity in the children.
  • There is no established Daily Value for omega-3 fatty acids. However, the American College of Obstetricians and Gynecologists and the European Union recommend 200 mg DHA/day during pregnancy and lactation.
  • This recommendation is based partly on the amount of DHA needed for brain development and partly on the FDA warning that pregnant women should not consume more than 2 servings of fish/week due to heavy metal and PCB contamination.
  • This recommendation can be met by 1-2 six ounce servings/week of fish or a fish oil supplement containing 550 – 600 mg of omega-3 fatty acids.
  • Many pregnant women avoid fish because of concerns about contamination with heavy metals and PCBs, both of which are neurotoxins. Therefore, the major source of omega-3s in the American and Canadian diets are short chain omega-3 fatty acids that are only inefficiently (1-4%) converted to DHA.
  • Consequently, experts have been concerned for some time that American and Canadian women may not be getting enough DHA during pregnancy and lactation, but it was not clear how serious an issue this was.
  • A recent study done with a group of 600 women enrolled in the Alberta Pregnancy Outcomes and Nutrition study found that:
  • Only 27% of pregnant women and only 25% of postpartum women who were breastfeeding met the recommendation of 200 mg of DHA/day. In short, nearly three-quarters of the women in the study were not getting enough (DHA) omega-3 during pregnancy and lactation.
  • When the women who were taking DHA-containing supplements were excluded from the data analysis, only 13% of pregnant and lactating women were getting enough DHA from their diet. . In short, nearly 90% of the women relying on diet alone were not getting enough DHA.
  • Taking a DHA-containing supplement increased the likelihood of achieving the recommended 200 mg DHA/day by 10.6 fold during pregnancy and 11.1 fold during breastfeeding.
  • This was a very affluent, well-educated group of women. If any women anywhere are getting enough DHA during pregnancy and lactation, this should have been the group that was.
  • The authors concluded “Our results suggest that the majority of participants in the cohort were not meeting the EU recommendations for (DHA) omega-3 during pregnancy and lactation, but taking a supplement significantly improved the likelihood that they would meet the recommendations.”

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.

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,
