A case report recently published in the Journal of the Canadian Medical Association reminds us how important Vitamin D is to our health. In this case, a woman after a normal pregnancy and full term delivery had an otherwise normal looking baby whose bones had failed to fully solidify in his skull. It turned out that she had been very deficient in Vitamin D during her pregnancy and after about three months of proper nutrition the babyâs bones grew in properly and everything went back to normal. This case highlights how essential Vitamin D is for the health of our bones at any age. There are nutritional sources â oily fish like salmon, red meat, liver, egg yolks, and fortified foods such as some dairy products â but itâs tough to get enough from diet alone. Fortunately during most of the year the sunâs rays striking our faces and arms for about 15 minutes a day is enough to naturally produce within our skin the levels of vitamin D that most of us need. This slows down a bit as we age and also is reduced dramatically from October to March in our northern latitudes because of the angle of the sun, not to mention how many more layers of clothing we wear.
