Is Vitamin D Associated With Heart Disease Risk?

Author: Dr. Stephen Chaney

 

vitamin-d-reduce-cholesterol-childrenNot too many years ago, we thought of vitamin D as affecting bone density and little else. Then we discovered that almost every cell in our body has vitamin D receptors. This has lead to research suggesting that vitamin D affects our health in many ways that were unimaginable only a couple of decades ago.

For example, low vitamin D levels are associated with increased risk of heart disease. The linkage between vitamin D and heart disease has not been proven. Nor do we know the mechanism. However, this has lead to ongoing research asking if there is any relationship between vitamin D and cholesterol metabolism.

The answer appears to be yes. Several studies have suggested a correlation between low vitamin D levels and elevated total cholesterol, LDL cholesterol, and triglycerides – all risk factors for heart disease.

The next question is how early in life is this correlation found. Again, some studies have suggested that the same correlation between low vitamin D and high levels of unhealthy lipids are found in teens. But, what about pre-teens, children who haven’t gone through puberty yet? That’s what this study was designed to determine.

 

How Was The Study Done?

vitamin-d-reduce-cholesterol-children studyThe current study  was based on data collected from 419 children, ages 6-8, in the Physical Activity and Nutrition in Children (PANIC) Study in Eastern Finland. This was a lifestyle study that collected information on body weight, diet, and activity levels.

Fasting blood samples were also collected and analyzed for blood lipid levels (total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides) and for 25-hydroxyvitamin D (25(OH)D), which is considered the most accurate measure of vitamin D status. The National Institutes of Health considers:

  • <30 nmol/L of 25(OH)D an indicator of vitamin D deficiency.
  • 30 to <50 nmol/L 25(OH)D an indicator of vitamin D insufficiency.
  • ≥50 nmol/L 25(OH)D an indicator of adequate vitamin D status.

To put this study in perspective, vitamin D status is a major concern in Finland because of its proximity to the Arctic Circle. There is little sunlight in the winter, and, although the days are long in the summer, the sun is weak. The major sources of vitamin D in the Finnish diet are fish, vitamin D-fortified fluid milk products, vitamin D-fortified fat spreads, and vitamin D supplementation. Vitamin D fortification was introduced in Finland in 2003. Vitamin D supplementation has also become increasing popular. The number of people using vitamin D supplements has increased from 11% in 2000 to 41% in 2011.

A recent study  looking a vitamin D status between 2000 and 2011 found that the combination of food fortification and vitamin D supplementation has been successful at improving vitamin D status in the Finnish population, increasing average 25(OH)D levels from 48 nmol/L to 65 nmol/L.

 

Does Vitamin D Reduce Cholesterol In Children?

vitamin dIn this study the mean serum 25(OH)D in the children was 68.1 nmol/L. 20% of the children had serum 25(OH)D below 50 nmol/L, and only 4 children (1%) had serum 25(OH)D below 30 nmol/L. When 25(OH)D levels were compared with blood lipid levels:

  • Higher serum 25(OH)D levels were associated with lower plasma levels of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides.
  • The association between higher 25(OH)D levels and lower blood levels of total cholesterol, LDL cholesterol, and HDL cholesterol remained after correcting for weight, physical activity, sedentary behavior, diet, daylight time, parental education, and genetic mutations known to affect vitamin D metabolism.

What Does This Mean For You?

I don’t want to overinterpret the study. Not all studies show an inverse association between 25(OH)D and cholesterol levels. Most of the previous studies have also indicated that higher 25(OH)D levels were associated increased HDL levels, while this study found higher 25(OH)D levels associated with decreased HDL levels. Much more research needs to be done.

However, this study is yet another indication that optimal vitamin D status may be important for heart health, even in young children. While the correlation between vitamin D status and heart health is not definitive at present, virtually everyone agrees that adequate vitamin D status is a good thing.

My recommendations are to:

  • Get as much vitamin D as possible from vitamin D-fortified foods, oily fish, and sensible sun exposure.
  • Get your serum 25(OH)D level determined and take vitamin D supplements if it is low.

 

The Bottom Line

 

A recent study of vitamin D status in Finnish children ages 6-8 found:

  • Higher vitamin D status was associated with lower plasma levels of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides.
  • The association between better vitamin D status and lower blood levels of total cholesterol, LDL cholesterol, and HDL cholesterol remained after correcting for weight, physical activity, sedentary behavior, diet, daylight time, parental education, and genetic mutations known to affect vitamin D metabolism.

This study is another indication that optimal vitamin D status may be important for heart health, even in young children. While the correlation between vitamin D status and heart health is not definitive at present, virtually everyone agrees that adequate vitamin D status is a good thing.

My recommendations are to:

  • Get as much vitamin D as possible from vitamin D-fortified foods, oily fish, and sensible sun exposure.
  • Get your serum 25-hydroxyvitamin D level determined and take vitamin D supplements if it is low.
  • Make sure your children are getting enough vitamin D in their diet and have optimal serum 25-hydroxyvitamin D.

Biceps Pain Caused by a Tiny Muscle

An Unexpected Cause Of Biceps Pain

It’s Spring In Florida

spring flowersMarch is a beautiful time of year here in Florida, and it’s the beginning of Spring for our friends and relatives in the northern states.  I lived most of my life in New York, and I loved when the purple crocuses started peeping up through the snow.  Spring was on its way!

Of course, on March 17th there is also that fun holiday – St. Patrick’s Day.  The parade in New York City is the largest St. Patrick’s Day parade in the world, followed by Dublin. In fact, the first parade in New York was in 1762, a full 14 years before the signing of the Declaration of Independence.  It’s a huge party, a parade that lasts for hours officially, and then the party continues for many more hours unofficially.

Everyone is Irish on St. Patrick’s Day!  So, whether you are born Irish, or you’re just Irish for the day, I wish you this popular Irish blessing…

“May the road rise up to meet you

May the wind be always at your back

And may the sun shine be warm upon your face.”

 

A Tiny Muscle Can Cause Shoulder And Arm Pain

biceps pain subclavius muscleA tiny muscle that can cause biceps pain.

There is a pencil thin muscle that runs from the cartilage of your 1st rib to the end of your clavicle (collar bone). The name of the muscle is Subclavius.

The subclavius muscle lifts your first rib when you inhale so your lungs can expand, and it also stabilizes the joint between your clavicle and your sternum.  It’s a small muscle and most people aren’t aware of it, or how it helps us.

Normally this muscle is not repetitively strained, however during a time of rapid breathing it can go into spasm.  Perhaps you have a cough and you are doing sudden, rapid breaths. Or, maybe you are a runner and you’re breathing rapidly. Anything that makes you take deep breaths quickly can cause muscle spasms to form in your subclavius muscle.

As shown by the green shading on the chart, the referred pain for the subclavius goes across the entire length of the front of your shoulder, and then continues down biceps muscle on the front of your arm.  The darker shading demonstrates where the greatest pain is felt. While the pain is most frequently felt in the shoulder, biceps pain can also occur.

 

An Unexpected Cause Of Biceps Pain

biceps pain treatmentIf you have pain in your biceps muscle, you may not consider that a muscle spasm in the top/front of your chest is the source of the problem. If rubbing and stretching your biceps isn’t giving relief, you are stuck for a solution.  Yet, just putting direct pressure on the spasm, located at your sternum, just under your collarbone, will solve the problem.

Press your finger directly onto the spot.  If you don’t find a tender point, move ½” toward the outside and continue pressing until you find a tender point.  This is the spasm that is causing the pain pattern.

It’s as simple as that!

 

Wishing you well,
