Almost everyone knows that Vitamin D is the main player from the team of vitamins that keeps bones strong.  Milk is quite often supplemented, or fortified, with Vitamin D, as to aid in efficient calcium absorption by the body.

Now, new data suggests that Vitamin D is also critical to an efficient and fully functional immune system.  Older research has demonstrated a link, albeit only coincidentally and not causally, between Vitamin D supplements taken during pregnancy and a reduced risk of lung and breathing problems in offspring.

A recently published paper in the scientific journal Pediatrics presents data in which medical doctors have quantified the Vitamin D content of umbilical cord blood from nearly 1000 newborn babies in New Zealand.  That is not all.  The team of researchers then followed up with these tikes five years later and assessed how they were doing.

It turns out that those infants whose cords had the highest levels of Vitamin D were found to be two times less likely to have infections of the lungs and a reduced chance of wheezing during breathing.  The high Vitamin D kids, however, did not exhibit a difference in the prevalence of asthma, offering further evidence that asthma may be more often caused by environmental conditions, rather than genetic or nutritional considerations.
