dha during pregnancyDo women need DHA during pregnancy?  Most experts agree that omega-3 fatty acids, especially DHA, are essential for fetal development during pregnancy and for brain development through at least the first two years of a child’s life. That’s because DHA is an important component of the myelin sheath that coats and protects our brain neurons.

During the last two trimesters of pregnancy and the first two years of a child’s life, their brains are growing and maturing at a remarkable rate. The need for DHA during this critical period is huge, and most of that DHA comes from the mom. That’s why the mom’s intake of DHA during pregnancy and breastfeeding is so important.

For example, higher intakes of omega-3s during pregnancy and breastfeeding have been associated with:

  • Decreased maternal depression.
  • Increased birth weight.
  • Reduced risk of preterm birth.
  • Reduction in ADHD symptoms.
  • Reduction in allergies and asthma.
  • Improved developmental and cognitive outcomes such as:
    • Increased visual acuity.
    • Better problem-solving skills.

I do wish to acknowledge that there is still debate in the scientific literature about the strength of some of these associations. However, there is enough cumulative evidence for the beneficial effects of omega-3s especially DHA during pregnancy and breastfeeding that virtually all experts agree adequate maternal omega-3 intake is important during this crucial period in a child’s life.

 

How Much DHA During Pregnancy & Breastfeeding Is Needed?

fish oil dha during pregnancyThe National Academies of Science have not yet set a Daily Value for omega-3s. However, a group of experts met in 1999 to recommend adequate dietary intake of omega-3s (Simopoulos et al, Prostaglandins, Leukotrienes & Essential Fatty Acids, 63: 119-121, 2000 ). They concluded that an adequate intake of omega-3 fatty acids in adults was at least 650 mg/day with at least 440 mg/day of that coming from EPA + DHA (220 mg/day each of EPA and DHA). They further recommended that DHA intake in pregnant and lactating women should be at least 300 mg/day.

However, because of concerns about seafood contamination with heavy metals and PCBs (both of which are neurotoxins), the FDA recommended in 2004 that pregnant and lactating women limit seafood consumption to two servings a week, which amounts to about 200 mg/day of DHA. This has been subsequently adopted by the American College of Obstetricians and Gynecologists and the European Union as the recommended amount of DHA during pregnancy and lactation (Coletta et al, Reviews in Obstetrics & Gynecology, 3, 163-171, 2010 ).

How Was The Study Done?

The authors of this study (Nordgren et al, Nutrients, 2017, 9, 197; doi:10.3390/nu9030197 ) utilized a nationwide database called NHANES (National Health and Nutrition Examination Survey). NHANES data are based on an annual survey conducted by the National Center for Health Statistics (NCHS) to assess the health and nutritional status of adults and children in the United States, and to track changes over time.

Dietary intake of nutrients is based on two interviewer-administered, 24-hour dietary recalls conducted 3-10 days apart. Omega-3 intake was calculated based on the USDA database of nutrient composition of foods.

The investigators combined NHANES data from the years 2003 to 2012. This included 6478 women of childbearing years (14-45 years old), of which 788 were pregnant at the time of the survey.

Are Pregnant Women Deficient In Omega-3s?

omega3 deficiency in pregnant womenThe results of this study were alarming:

  • Mean EPA + DHA intake was only 89 mg/day with no difference between pregnant and non-pregnant women of childbearing age.
  • This contrasts to the expert committee’s recommendation of at least 440 mg/day for EPA + DHA (220 mg/day each from EPA and DHA).
  • Mean DHA intake was only 66 mg/day in pregnant and 58 mg/day in non-pregnant women of childbearing status.
  • This contrasts to the recommendations of 200 – 300 mg/day for pregnant women.
  • These intakes did not include dietary supplements, but only 1.8% of non-pregnant and 9% of pregnant women in this survey took supplements containing EPA and/or DHA.

The authors concluded “Our results demonstrate that omega-3 fatty acid intake is a concern in pregnant women and women of childbearing age…” They went on to say: ‘Strategies to increase omega-3 fatty acid intake in these populations could have the potential to improve maternal and infant health outcomes.”

What Do Other Studies Show?

This study is not an outlier. In a previous issue  Do Women Get Enough Omega-3 During Pregnancy of “Health Tips From the Professor” I reported on a study showing that 90% of Canadian women were not getting enough DHA in their diet. A similar study in Germany concluded that 97% of middle-aged women had suboptimal omega-3 status (Gellert et al, Prostaglandins, Leukotrienes and Essential Fatty Acids, doi: 10.1016/j.plefa.2017.01.009 ).

More importantly, these omega-3 deficiencies matter. In another issue DHA Supplements During Pregnancy of “Health Tips From the Professor” I reported on a study showing that DHA supplementation significantly reduced preterm births. Based on that effect alone, the authors concluded that DHA supplementation during pregnancy could save the US healthcare system close to $6 billion/year.

Women do need DHA during pregnancy.

The Bottom Line

  • Optimal intake of omega-3s during pregnancy and breastfeeding is associated with:
    • Decreased maternal depression.
    • Increased birth weight.
    • Reduced risk of preterm birth.
    • Reduction in ADHD symptoms.
    • Reduction in allergies and asthma.
    • Improved developmental and cognitive outcomes such as:
      • Increased visual acuity.
      • Better problem-solving skills.
  • In 1999, a panel of experts met to set standards for omega-3 intake. They recommended:
    • At least 650 mg/day for adults with at least 440 mg/day coming from EPA + DHA (220 mg/day each of EPA and DHA).
    • At least 300 mg/day of DHA for pregnant and breastfeeding women.
  • Because of concerns about seafood contamination with heavy metals and PCBs (both of which are neurotoxins), the FDA reduced the recommendation for pregnant and breastfeeding women to 200 mg/day of DHA. That recommendation has been subsequently adopted by the American College of Obstetricians and Gynecologists and the European Union.
  • A recent study has found:
    • Mean EPA + DHA intake was only 89 mg/day with no difference between pregnant and non-pregnant women of childbearing age.
      • This contrasts to the expert committee’s recommendation of at least 440 mg/day (with 220 mg/day each from EPA and DHA).
    • Mean DHA intake was only 66 mg/day in pregnant and 58 mg/day in non-pregnant women of childbearing status.
      • This contrasts to the recommendations of 200 – 300 mg/day for pregnant and breastfeeding women.
    • These intakes did not include dietary supplements, but only 1.8% of non-pregnant and 9% of pregnant women in this survey took supplements containing EPA and/or DHA.
    • This study is in line with recent studies in Canada and Germany. Clearly pregnant and Breastfeeding women in developed countries like the US are getting suboptimal amounts of omega-3s in their diet.
    • This is alarming because these findings come amidst mounting evidence that optimal omega-3 intake during pregnancy and breastfeeding is important for the health of both mother and child.

Stress and Jaw Pain

Get Rid Of Jaw Pain Forever

Author: Julie Donnelly, LMT – The Pain Relief Expert

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,
