Thiel: Study reinforces suspected importance of vitamin D

It is estimated that over 80 per cent of individuals in this specific climate are vitamin D deficient.

Last month, the Journal of Clinical Endocrinology and Metabolism published an interesting paper regarding vitamin D levels in childhood and increased likelihood of developing atherosclerosis in adulthood.

The study was conducted by Dr. Markus Juonala, of the University of Turku, Finland.

Juonala and his researchers found that low levels of vitamin D in childhood were associated with increased carotid artery thickness almost 30 years later, particularly in females.

There has been an overwhelming amount of previous compelling research citing the importance of vitamin D and the further enhancement of the immune system, especially during the months of less exposure to sunlight (October to March).

The American Journal of Clinical Nutrition produced a study in May 2010 that demonstrated clearly that children who had sufficient vitamin D levels have a marked reduction in the number of colds and flu’s as opposed to those children that did not have sufficient vitamin D levels.

It is estimated that over 80 per cent of individuals in this specific climate are vitamin D deficient.

One study cited that in the last five years, childhood deficiencies of vitamin D has increased by more than 200 per cent.

The Royal Children’s Hospital, in Melbourne, Australia, stated that deficiencies in vitamin D and children can lead to other health problems such as a higher risk of bowel cancer, heart disease, high blood pressure, stroke, problems with immunity (how the body fights infections) and autoimmune diseases (including diabetes).

For Juonala’s study, the researchers examined data gathered from 2,148 individuals in 1980. The subjects were between the ages of three and 18 years.

Blood samples were taken once again at the 27th year follow-up, in 2007. In his study, they performed ultrasound measurements of the left carotid artery in all of the subjects.

The analysis demonstrated that the girls in his study had significantly lower vitamin D levels than their counterparts, the boys in the study.

In addition, they found that there was more severe carotid artery narrowing in the females, but not in the males.

There was a correlated effect in the study, for instance, those in the 90th percentile of vitamin D deficiency developed significant adult risk ratios for atherosclerosis.

Though the study had several criticisms, claiming that it was merely an observational study, it was clear that the implications of the study provided enough evidence that further clinical studies need to be implemented with respect to vitamin D levels in children and cardiovascular health in later years.

The vitamin D is one of the supplements that are on the radar today with respect to consideration and research.

I think it should be an important part of everybody’s supplement regime, especially during these winter months and especially with our children.
