Red alert: vitamin D deficiency in children

A few weeks ago someone finally issued a red alert for our children, how vitamin D deficiency may be injuring them in ways we can’t imagine. I love how the authors wrote that their findings should be:

“regarded as a public health emergency by all stakeholders.”

Indeed, who is not a stakeholder when it comes to our 9-12 year-old children?


At 35 degrees North, Dr. Tirang Neyestani and colleagues in Tehran, Iran, found that in the winter, 91% of the children had vitamin D levels lower than 20 ng/ml, 86% lower than 15 ng/ml, and an unbelievable 38% had vitamin D levels lower than 5 ng/ml. For reasons I will not repeat, low levels are usually more reliable than high levels and this study used the German made “Immunodiagnostik” method to measure vitamin D levels.

Red alert it should be in the USA but no, we have just been subjected to the opinion of a seemingly well-intentioned group of apparently unbiased scientists from the Food and Nutrition Board who said that vitamin D is for bone and bone alone and levels of 20 ng/ml are just fine. Natural selection will take care of those who actually believe that.
