A study published in the Journal of Paediatrics suggests that children who are deficient in vitamin D are three times more likely to have food allergies, especially to milk and wheat.
Low levels of vitamin D are caused by genetic factors as well as not being exposed to sufficient sunlight, the main source of the vitamin.
Researchers are looking to vitamin D deficiency as a cause of allergies, as the vitamin is tied to the reduction of inflammation and regulating the immune system.
