Are Pregnant Women Deficient In Omega-3s?

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.

Calf Cramps Remedy

Posted February 20, 2018 by Dr. Steve Chaney

Don’t Let A Leg Cramp Stop You Short

Author: Julie Donnelly, LMT – The Pain Relief Expert

calf cramps remedyGetting a leg cramp while you are running can be the “straw that broke the camel’s back.”  If you don’t treat it properly and quickly when it is happening, you may limp to the finish line, and you can suffer from its effects for days afterward.  I will show you the best calf cramps remedy below.  First, let’s go over spasms and muscle cramps.

A spasm and a cramp are similar because it’s a shortening in the muscle fiber, but that’s where the similarity ends. A spasm is a slow-forming shortening of a group of fibers that tie up into a knot in the muscle. You can feel a spasm with your fingertips, it feels like a bump as you slide along the full length of the muscle. With a spasm, as you press down and slide, it doesn’t hurt until you get to the spasm, and then it can really hurt. But then it stops hurting as you slide off the spasm. A spasm refers pain to the insertion points of the muscle and frequently doesn’t hurt where the spasm has formed (that is, until you press on it).

Why Do Your Muscles Cramp?

calf cramps remedy muscle crampsA cramp (Charlie horse) is when all the fibers of the entire muscle suddenly and violently contract. The muscle will quickly shorten and can go into a huge knot, or it will just totally shorten.

Usually a cramp happens in your calf muscle, although it can happen to any muscle in the body.  Your calf is comprised of two major muscles, the gastrocnemius and soleus. The gastrocnemius, which is shown in this graphic, originates behind your knee and inserts into your Achilles tendon.

Visualize the muscle suddenly shortening, pulling up on your Achilles tendon, and becoming a mass of tight knots through the entire muscle.

Muscles have an “all or nothing” response.  This means that when a muscle fiber contracts, it will shorten 100% of its length.  It never starts to shorten and then make a U-turn and lengthen.  A cramp is seriously painful, and if you try to stretch it out as it’s happening, you can tear the muscle fibers. In fact, that’s the reason it hurts for sometimes days after the cramp.

A Calf Cramps Remedy You Can Administer Yourself

calf cramps remedy squeezeThe best thing to do is to squeeze the two ends of your calf muscle together, which will help the cramp complete as quickly as possible. This will hurt, but for less time than the normal cramping process.  Hold your calf tightly, as shown in this picture, and continue to press the two ends toward each other.

Hold it until you can breathe normally (about 30-45 seconds), and then release. Breathe for a minute or so, and then push the two ends together again.  This second time won’t hurt, you are only doing it to make sure that all the fibers have completed the contraction.

There are many ways to self-treat your calf. If you are out on the road you can either sit on a bench or lie on the ground and put the sore calf onto your opposite knee.  Press down and hold the pressure for 30 seconds. Then deeply press along the muscle going from the back of your knee toward your ankle.

calf cramps remedy opposite footYou can also use your opposite heel and press deeply, straight into your calf.

Start at the top of the muscle and move down toward your ankle. Stop whenever you come to a point that is especially painful. The point should be close to the area shown in this picture.

Hold the pressure for 30-60 seconds, or until it doesn’t hurt anymore.  Release, and then repeat 2-3 times.

Complete this self-treatment by squeezing your calf muscle, like you are wringing out a wet towel.  This will force blood into your muscle and get your circulation moving again.

Proof That My Treatments Work

I once taught this technique at an Ironman Triathlon during a 15-minute session I was giving to the triathletes.  Several days later a triathlete emailed me and told me that he had a cramp as he was running, and he did the treatment I’d taught him.  It cost him a few minutes (he wasn’t in the top three, so the time loss wasn’t a huge issue) but he was able to get up and get back to running, totally without pain.

About a mile later he got a cramp in the other leg, but he automatically started to just stretch it like he’d always done before.  He ended up limping all the way to the finish line, and days later it was still hurting.  He wanted to let me know that my cramp treatment really worked great.  This was especially helpful because I’d always wondered what body chemistry did to the outcome of treating a cramp, and here I found out that chemistry wasn’t involved in the treatment of the muscle fibers.

What To Do After The Calf Cramps Remedy

If the cramp happens during a race or athletic event, knowing how to stop it, and these quick massage techniques, will get you back into the game. But it hasn’t totally resolved the issue. Finally, when you have the time to be detailed (after the race, in the evening, etc.), it is important to work out all the spasms and then stretch properly.

When you are treating the muscles afterward, I suggest you consider getting an analgesic cream that goes way deep into the muscle fibers. Use it when you are massaging the muscle, but don’t put it on before you play, run, or before/after a shower because it will go too deep into the muscle and burn like crazy. After you do the treatments, use ice &/or arnica gel (get it at a good health food store) to heal the bruised muscle fibers and help with pain and swelling. Arnica is fantastic, it’s an amazing homeopathic remedy that has been around for ages and really works.

Naturally you will also want to make sure you hydrate properly and that your diet, vitamins and minerals are all in balance.
