Vitamin D, Winter Babies, and Food Allergies
04.28.10 Vitamin D, Winter Babies, and Food Allergies
March isn't winter in most of the country, but it sure is in Vermont. Even as I write this in late April, we have about 4 inches of snow on the ground, and counting. Anyway, my oldest daughter was born in March, and she also have has a severe peanut allergy. What do these have to do with each other?
I read with interest this article about winter born babies and food allergies. It is looking like there is an beginning evidence that winter born babies have a higher chance of being allergic to foods, based on their vitamin D deficiency. This is a problem where I live, because the sun rarely shines from November to March (maybe I am being a bit dramatic--). I've since begun giving my girls vitamin D daily if they have spent no time in the sun that day (like today, while it snowed continually on my growing tulips).
"Exposure to low vitamin D levels in the womb, immediately after birth and during early childhood may be key.
Previous studies have associated month of birth with other allergic conditions such as asthma, recurrent wheezing and dermatitis."
That makes sense for me, because during my pregnancy it was winter, and I definitely didn't have enough D in my system. Obviously this is only one factor in determining the causes of food allergies-- but it certainly warrants more research. I would encourage pregnant moms and mothers of newborns to try and get enough vitamin D, to promote strong immune systems in both of you!
