Iron and the Teen Brain

iron and brain development in teensFor those of you with teenagers – or who have had teenagers in the past – you may suspect that there’s nothing between their ears. But actually there is a lot going on between their ears, and some of the neural contacts laid down in the brain during the teen years influence the health of their brain during their adult life.  Let’s look at the association between iron and brain development.

And – no surprise here – what they eat can affect the health of their brain as well.

Which brings me to a study published in the Proceedings of the National Academy of Sciences January 9, 2012 (doi: 10.1073/pnas.1105543109) that looks at the adequacy of dietary iron intake during the teenage years and their brain health as adults.

Basics of Iron Metabolism

Before I describe the study perhaps a little bit of what I call Biochemistry 101 is in order.

Free iron is toxic to living cells. For that reason, our body produces multiple proteins to bind and transport the iron. The protein that binds and transports iron through the bloodstream is called transferrin. Under normal conditions 2/3 of the transferrin in our bloodstream has iron bound to it and 1/3 does not. And that is the ideal ratio of bound and unbound transferrin for delivery of iron to brain cells and other cells in our body.

When our diet is iron deficient (or we have excessive blood loss) the percent iron saturation of transferring decreases. The body tries to compensate by producing more transferrin, but this doesn’t really help since the problem was inadequate iron supply, not inadequate transferrin supply. As a consequence elevated transferrin levels are generally indicative of an iron-deficient diet.

Iron and Brain Development in Teens

iron and brain developmentThe study was led by Dr. Paul Thompson of the UCLA Department of Neurology. He and his team performed brain scans on 631 healthy young adults with an average age of 23. The brain scans were of a type that measured strength and integrity of the connections between the nerves in the brain – in other words, the brain’s wiring. They then went back and looked at the amount of iron available to each subject’s brain during adolescence by looking at their blood transferrin levels from routine physical exams performed at ages 12, 14 and 16 (blood transferrin levels are often measured as part of routine physical exams).

The results were pretty clear cut. Elevated transferrin levels during the teenage years were associated with reduced brain-fiber integrity in regions of the brain that are known to be vulnerable to neurodegeneration. These individuals did not show any cognitive impairments as young adults, but the concern is that they might be more likely to develop cognitive impairments as they age.

Dr. Thompson summarized his team’s findings by saying that “Poor iron levels in childhood erode your brain reserves which you need later in life to protect against aging and Alzheimer’s. This is remarkable, as we were not studying iron deficient people, just around 600 normal healthy people. It underscores the need for a balanced diet in the teenage years, when your brain command center is still actively maturing.”

Questions Every Parent Should Ask

If you have teenagers you might want to ask yourself questions like:

  • What is your teenager’s diet like?
  • Is it balanced?
  • Are you sure that it meets their nutritional needs?
  • Should you consider supplementation to make sure that they are getting all of the nutrients that they need?

 

The Bottom Line

  • A recent study suggested that inadequate iron intake in the teenage years may affect how our brains are wired in our adult years. The authors of the study interpreted the study as suggesting that an inadequate diet during the teen years could predispose us to cognitive decline and Alzheimer’s as adults.
  • This study only looked at structural differences in the brain circuitry. We can’t conclude from this study alone that inadequate iron intake as a teenager will doom somebody to cognitive impairment and increased Alzheimer’s risk as they age. But we can conclude that adequate iron intake during adolescence is required for normal brain development.
  • And it’s probably not just iron. This study focused on iron status because transferrin levels are routinely measured during physical exams so it was easy to go back and determine what each subject’s iron status was during their teenage years. Many other important nutrients are required for normal brain development, but we don’t have an easy way of going back and determining what someone’s nutritional status was for those nutrients in their teen years. What was shown to be true for iron in this study is likely to be true for other nutrients as well.
  • These were normal teens eating a normal American diet. They weren’t from a third world country and there was nothing weird about what they were eating. But, clearly some of the subjects in the study weren’t getting the iron that they needed from diet alone.
  • The teen years are a time of rapid growth and maturation. It’s not just the brain that needs the proper balance of nutrients during the teen years. All of their tissues require proper nutrition.

What Is The Pectineus Muscle And Why Is It Important?

Spring Is In The Air

spring floridaI remember as a child we sang “Though April showers may come your way…they bring the flowers that bloom in May…”

Of course, here in Florida we are blessed with flowers all year, but there’s still a lovely feeling that happens in Spring.  It’s still cool enough most days to go out running, and the humidity is still low.  Traffic will soon be easing up as our friends from the north start their trek back home, and daylight savings time is giving us more time to get to the beach for sunset.  Lovely!

Fun Facts About Spring….

  • The earliest known use of the term “spring cleaning” was in 1857
  • The word “spring” has been used for the season since the 16th century
  • The first day of spring is called the vernal equinox
  • On the first day of spring, the sunrise and sunset are about 12 hours apart everywhere on earth
  • Spring fever isn’t just a saying. Experts say the body changes due to the temperature and can cause an upset in your health.
  • The actual start of spring varies from March 19th to the 21st, but it is commonly celebrated on the 21st.

Do you like to garden?  Now is the perfect time to get your gardens planted so you’ll have home grown veggies for the entire summer.  For me, it’s also a great time to do some spring cleaning and get the house in order before the summer closes all the windows and the air conditioning becomes our indoor relief.

But these activities can also cause a strain on muscles, so don’t forget to take care of yourself. If you put too much strain on muscles you haven’t used all winter, you can develop problems and need groin pain relief.

 

A Tiny Muscle Can Cause Groin Pain

groin pain relief pectineusLately I’ve had several clients come in because of groin pain that has their medical practitioners stumped.  Their symptoms are varied, but most complain that it feels like they hit their pubic bone with a rubber mallet.  Ouch!

One client loves to ride her horse, but the pain had prevented that for several weeks. Another was considering selling the motorcycle that she and her husband love because she just can’t sit on it anymore.

Several years ago, I had a male client tell me that he had this same pain and he was told it could be his prostrate causing the issue.  Fortunately, that wasn’t he problem at all.

The muscle that caused all these problems, and a lot more, is the Pectineus.

The Pectineus muscle originates on your pubic bone and inserts into the very top of your inner thigh bone (femur).

You can see the Pectineus and surrounding muscles more clearly by going to https://en.wikipedia.org/wiki/Pectineus_muscle

Most muscles have more than one function, and this is true for the Pectineus.  The function we’ll look at today is called adduction.  It brings your leg in toward midline.  If you think of a soccer player kicking the ball with the inside of his ankle, it was the Pectineus that helped draw his leg in so he could do the shot.

Each of my clients had pain while trying to bring their leg out so they could sit on their horse, or on their motorcycle.  The tight muscle was pulling on their pubic bone and causing a severe strain.

This muscle is easier to have someone else treat it for you because of its location but give it a try and see if you can locate & treat it yourself.

To reach the Pectineus, move the ball all the way up to the crease in your leg.  You can do the treatment with a ball, but because of the size of the muscle and its location, it’s easier to do it with your fingertips.

Sit as this athlete is sitting, and even bring your opposite leg up so your foot is flat on the floor.  For example, in this picture, the athlete would bring her right leg up so her right foot is on the floor, and then lean a bit further onto her left hip.  That opens up the area so she can reach a bit easier into the muscle while using her fingertips.

Press into the muscle, being careful to feel for a pulse, and moving if you feel one.  If the Pectineus is in spasm, you’ll know it immediately when you press on it.  If it’s not in spasm, you won’t be able to find it at all.

Remember to stay within your pain tolerance level, this isn’t a “no pain, no gain” situation.  Never go deeper than what feels tender, but not so much that you want to faint. Hold the pressure for 15 seconds. Then let up on the pressure, but keep your fingers in the same place.

Repeat this movement several times. Each time it will hurt less, and eventually it won’t hurt at all.  That’s when the muscle has completely released, and you will have relief from the pain.

It’s as simple as that!

Why stay in pain when it’s so easy to find the muscular source of the problem and eliminate it?
