Food allergies caused by lack of sunlight

Food Allergies Linked with Lack of Vitamin D and Sunshine

We already knew sunshine and vitamin D were important to health – given the over 70 diseases now associated with their deficiency. Now research is proving their role in food allergies.
Researchers from the University of Melbourne have determined that children who had lower levels of vitamin D are more likely to have multiple food allergies.
The researchers tested 5,276 one year-old children. They gave the children skin prick tests to determine their allergies to peanuts, eggs, sesame, cow’s milk or shrimp. They also analyzed blood samples from 577 children, of which 344 had food allergies and 74 more sensitized but tolerant.
Australian children with parents who were vitamin D deficient were over 11 times more likely to have peanut allergens and nearly four times more likely to have a the allergies when compared to those who had healthy levels of vitamin D.
Overall, infants who were vitamin D deficient were over 10 times more likely to have multiple food allergies – meaning being allergic to more than two foods.
The researchers quantified vitamin D deficiency as having less than 50 and nmol/L of 25-hydroxyvitamin D in their blood, as measured by liquid chromatography with mass spectrometry.
The researchers wrote in their conclusion:

These results provide the first direct evidence that vitamin D sufficiency may be an important protective factor for food allergy in the first year of life.”
