Can DHA  Help Johnny Read?

Author: Dr. Stephen Chaney

Child-Reading-BookIf you are like most parents, you want to do everything you can to assure that your kids have the skills they need to succeed in school, and reading probably tops the list of necessary skills. If your child is reading below their age level, could something as simple as better nutrition improve their reading ability?

Recent studies have shown that the omega-3 fatty acids, especially DHA, play a very important role in normal brain function – especially memory, focus, concentration, and attention span.

I have shared with you previous studies which have shown that optimal DHA intake in pregnant women plays an important role in the early mental development of their children. On the other end of the age spectrum, studies have shown that optimal omega-3 fatty acid intake in older adults can delay cognitive decline.

I have also shared with you studies showing that omega-3 fatty acid supplementation in children with ADD and ADHD significantly reduce their symptoms. What about children without hyperactivity? Could omega-3 fatty acids affect their ability to learn?

Many Children Are Deficient in Omega-3 Fatty Acids

The Food and Nutrition Board has not yet set US standards for DHA intake, but the international standard is 200 mg for children 7 years old and older. Unfortunately, cod liver oil is a thing of the past, and foods rich in DHA are not particularly popular with children. Consequently, most children in this country are only getting around 20-40 mg of DHA per day.

And that shows up in their blood levels of omega-3 fatty acids. A recent study in England looked at blood levels of omega-3 fatty acids in 493 seven to nine year olds with below average reading performance who were enrolled in Oxfordshire primary schools (P. Montgomery et al, PLoS ONE, doi: 10.1371/journal.pone.0066697).

All of them had low blood levels of omega-3 fatty acids (both DHA and EPA), and the blood levels of omega-3 fatty acids were directly related to their reading ability. In non-scientific language that simply means that those with the poorest reading abilities had the lowest blood levels of omega-3 fatty acids.

This study is particularly significant because another study by the same group showing that DHA supplementation improved reading skills in underperforming children.

Could Omega-3s Improve Reading Skills?

This study (Richardson et al., PLoS ONE 7: e43909.doi:10.1371/journal.pone.0043909) looked at 362 normal 7-9 year old children enrolled in mainstream primary schools in Oxfordshire, England.

These children were all reading at significantly below the average for their grade levels. The study excluded children with specific medical difficulties that might affect their ability to read, children who were already taking medications expected to affect behavior or learning, children for whom English was not their first language, and children who were already eating fish more than twice a week or taking omega-3 supplements.

The children were given either supplements containing 600 mg of DHA per day or a placebo containing corn and soybean oil. At the end of 16 weeks the children were rescored on a standardized reading test.

Reading-ScoresThe results were quite interesting. When the scientists looked at children reading in the lower third of their class, the affect of DHA on their ability to read was non-significant. However, when they looked at the children who were performing in the bottom 20% of their class with respect to reading, DHA supplementation resulted in a 20% improvement in their reading score. And when they looked at children in the bottom 10% of their class with respect to reading, DHA supplementation resulted in a 50% increase in reading scores. These changes were highly significant.

To put this in perspective, the children performing in the bottom 20% of their class improved their reading efficiency by around 0.8 months with respect to their normal reading age, and the children in the bottom 10% of their class improved their reading efficiency by around 1.9 months with respect to their normal reading age.

Strengths and Weaknesses of The Studies

 

On The Minus Side:

  • First and foremost we must remember that nutrition is only one of many factors that can affect reading performance in children. You shouldn’t think of DHA as a magic bullet that will cure your child’s reading problems by itself.
  • This is a single pair of studies that need to be replicated.
  • This study does not establish the optimal dose of DHA needed to improve reading in underperforming children. Until dose response studies have been done we don’t know whether 600 mg is needed or whether simply making sure that the children reach the recommended 200 mg per day of DHA would be sufficient.

On The Plus Side:

  • Both of these were very well controlled studies, and they complemented each other perfectly.  One study showed that students with the poorest reading ability had the lowest blood levels of DHA. The other study showed that children with the poorest reading ability experienced the greatest improvement with DHA supplementation.
  • These studies were not done with third world children. They were studies with normal, healthy children in a prosperous European country.
  • These studies are fully consistent with previous studies looking at the effects of DHA on cognition in children.

The Bottom Line

What does this study mean for parents whose children may be struggling with their reading in school?

  • The lead author concluded: “We have shown that in the mainstream, general population, something as simple as DHA can benefit reading abilities in underperforming children.”
  • It’s perhaps not that ironclad yet. But if your kid or grandkid is reading below their grade level, DHA supplementation is both safe and inexpensive. It’s worth giving it a try.

    This is an extremely important study because everyday children are struggling with reading and cognitive abilities. I believed in DHA supplementation for over 31 years and I know that for my children it has been just wonderful.

How to Choose the Right Pillow

Posted April 17, 2018 by Dr. Steve Chaney

Wake Up Each Morning Pain Free

how to choose the right pillow without headachesThe way you sleep is often a key to discovering the cause of headaches and more. If you wake up with neck pain, a headache, or you suffer from ringing in your ears, dizziness, or ear pain, there is a good possibility that it may be caused by the way you are sleeping. Your pillow may be the culprit.  But if you need to know how to choose the right pillow for you, it’s easy.   It just takes a little “investigation.”

 

How to Choose the Right Pillow if You Sleep On Your Side

Your head, neck, and spine need to always stay in a nice straight line, just as it is when you are standing up, but that takes a little thought and understanding of the way you sleep.  So, get comfy in your bed and then notice how your head is resting.

how to choose the right pillow to sleep painfreeIf you sleep on your side, your pillow needs to be just the right size, so your head doesn’t point down toward the mattress (your pillow is too soft) or up to the ceiling (your pillow is too thick). Either of these positions will make the muscles on the side of your neck stay in the contracted position for hours and pull your vertebrae in that direction, especially when you try to turn over to your other side.

Your SCM Muscle May Cause Serious Problems

You also need to notice if you turn your head a bit, especially if you are turning into your pillow or turning your head up toward away from your pillow. In either of these two cases you will be causing your sternocleidomastoid (SCM for short) to be held shortened for hours.

Your SCM originates on your collarbone and inserts into the bone behind your ear.  When it contracts you turn your head to the opposite side. However, if the muscle is tight (for example, when you’ve held your head turned toward one side for an extended period of time) and then you bring your head back so you are facing forward, the tight muscle will pull on the bone behind your ear and cause havoc.

The symptoms for a tight SCM are tinnitus (ringing in the ear), dizziness, loss of equilibrium, ear pain, headaches, pain in the eye and around the skull, pain at the top of the head, and even pain in the throat. Amazing! What’s even more amazing is that it’s rare that this muscle is considered when a medical professional is searching for the cause of your symptoms.

These are the things to know when considering how to choose the right pillow if you sleep on your side.

How To Choose The Right Pillow If You Sleep On Your Back

how to choose the right pillow for sleeping on your backIf you sleep on your back, your head should be on the mattress (not propped up with a pillow) and you should have a tiny support (like a folded washcloth) under your neck.  Or, you can have a wedge pillow that starts at your mid-back and gently raises your entire trunk and head up while still allowing your head and back to be in a straight line.

It’s always a challenge for people who toss and turn during the night, sometimes on their side and sometimes on their back.  The best thing I’ve found for this situation is to have the pillow below shoulder level so when you turn on your side your shoulder will automatically slide to the edge of the pillow while still supporting your head properly, and when you turn onto your back, the pillow will start at shoulder level so your head and neck are supported, but your head is being pushed in a way that causes your chin to move down to your chest.

hip pain causes and treatment pain freeIt’s tricky, but I can personally attest to the fact that it will work.  I can always tell when I’ve had my head tilted (I toss and turn during the night) because I will wake with a headache. When that happens I’m grateful that I know how to self-treat the muscles of my neck and shoulders so the headache is eliminated quickly.  If you already have Treat Yourself to Pain Free Living,  you can self-treat all your neck and shoulder muscles to release the tension.

How To Choose The Right Pillow If You Sleep On Your Stomach

If you sleep on your stomach, this is the one position that is so bad that it behooves you to force yourself to change your position. Your head is turned to the side and held still for hours, putting a severe strain on all your cervical and upper thoracic vertebrae. Not only will this cause headaches, tinnitus, and a list of other pains, but it can cause problems down your entire spine. It can also impinge on the nerves that pass through the vertebrae on their way to your organs.

If you do sleep that way, let me know and I’ll give you some suggestions that work to change your habit of sleeping. It takes time and energy, but the results are worth the effort.

In every case, the way you sleep may cause neck pain that won’t go away until the pillow situation is resolved.

Now you should know how to choose the right pillow for the way you sleep.

Wishing you well,
