Whenever one of my clients tells me that they recently saw their doctor for a general checkup, they also tell me that their blood work indicated they were low in Vitamin D. I’ve just come to expect this.
Vitamin D occurs naturally in very few foods: wild salmon, herring, organ meats, egg yolks, mushrooms, and lard are about it. Milk has D added, as do some types of OJ and cereal. But it’s tough to get enough D just from food. The most effective way to get our Vitamin D is actually from the sun: It’s beneficial to expose your legs and arms for five to 10 minutes in mid-day summer sun, two or three times a week. And fortunately, our bodies can make enough vitamin D in the summer to last us all year, which comes in handy in sun-scarce winter when our bodies make virtually none.
There have been a plethora of reports stating that a lack of D can lead to such health problems as depression, high blood pressure, heart disease, and increased risk for some cancers and autoimmune diseases. The problem is that the medical community is not clear on exactly how much Vitamin D we need, or what constitutes “low” Vitamin D. For this reason, in the Annals of Internal Medicine the U.S. Preventative Services Task Force recommended against even getting our D routinely tested, unless you have bone-health problems or a condition that can affect fat absorption, such as celiac disease.
According to a report from Harvard Medical School, even if you test low for Vitamin D, there’s little evidence that taking a D supplement will do you any good. And too much D can actually cause calcium to accumulate in your blood, which can damage your heart, blood vessels, and kidneys.
Speaking with your own doctor about the D issue and how it affects your body would be a good course of action, as well as getting outside in this glorious summer sun. (And if you happen to like liver, go for it …)
