Low Vitamin D linked to allergiesPosted on March 5th, 2011 by Alison 8 Comments »
Children with low vitamin D levels were found to be 2.4 times more likely to be allergic to peanuts than children with adequate vitamin D levels, researchers discovered, according to a new study in the Journal of Allergy and Clinical Immunology. This was just one of 17 allergens tested in kids with vitamin D deficiency. These children were also more likely to be allergic to 11 of the 17 allergens tested, which included both environmental (such as oak and ragweed) and food (such as shrimp) allergens.
What does this mean? Researchers aren’t quite sure what the link means, but there has been a lot of emerging research about vitamin D deficiency and also about the role of vitamin D in protecting against various health conditions. Food allergies, like many other immune conditions, are on the rise, as is vitamin D deficiency.
In 2010 the Recommended Dietary Allowances (RDAs) for Vitamin D were raised to 400 IU/day for infants, 600 IU/day for people age 1-70, and 800 IU/day for those over 70 years old. In addition, the Tolerable Upper Intake Level (UL), meaning the dose at which there are no known adverse effects, was set at 4,000 IU/day for people age 9 or older, with gradually lower amounts for lower ages. See the National Institutes of Health Vitamin D fact sheet for more information.
These new RDA levels for vitamin D, though higher than before, are thought to be still too low, according to many researchers, doctors and health practitioners. I personally supplement with vitamin D (my levels tested low) and give my kids vitamin D supplements on the advice of a nutritionist and based on my own research. My experience is not meant to be taken as medical advice. I suggest that you see a health professional for his/her recommendations on vitamin D supplementation, especially if you suffer from any chronic health condition.
If you have undiagnosed celiac disease or gluten sensitivity, you may be at greater risk for vitamin D deficiency. Dr. Vikki Petersen explains the correlation very well in this video:
Research continues, and there’s a lot more to learn about vitamin D and its crucial role in our health.
