From my blog a few weeks back on the downside of nutrition “science,” you may remember that I am trying to avoid getting too excited about various nutrients - our health is much more complex than the addition (or elimination) of one or more nutrients. So, I had to check my enthusiasm when I read the recent headlines that vitamin D could be a ‘miracle drug’ and read some of the research for myself.
What We Know
We do know that many people have less than optimal levels of vitamin D.
A study in 2008 showed that Americans today have lower levels of vitamin D than 15-20 years ago. Also, it was found that half of all adults and children may have less than optimal levels and as many as 10% of children are highly deficient.
Vitamin D’s Role
Vitamin D’s primary function is to maintain normal blood levels of calcium and phosphorus; it aides in the absorption of calcium and helps to form and maintain strong bones.
New research suggests that vitamin D may also help lower the risk of diabetes, heart and kidney disease, high blood pressure, osteoporosis, hypertension, cancer and several autoimmune diseases.
Rational Steps
Before you rush out to purchase vitamin D supplements, just remember that the excitement about vitamin D is still ahead of the science. The results of these early studies come from observational research.
The findings may be flawed - it may be that high levels of vitamin D don’t make people healthier, but that the things healthy people do increases their vitamin D levels.
For example, individuals who spend more time being active outdoors receive more ultraviolet light exposure, which our bodies need to produce vitamin D. It might be the activity level that is increasing health, not the higher vitamin D.
While we are waiting for the results of more rigorous research, you might want to boost your vitamin D level, if you think you may be low. Your vitamin D levels are something you can discuss with your doctor and have checked. If s/he says that they are low, or if you suspect they may be and would like to increase those levels, consider some of the methods mentioned in this week’s tip.
I know that learning more about vitamin D inspired me to make sure my family is eating well, spending some time every day outdoors and taking our supplements. What do you make of this research - if anything - and what are you doing differently in your life because of it? What is your general reaction to knew health-related research and how do you treat it? Let me know in the comments!
