According to new research, pregnant women should avoid taking vitamin D supplements. A new survey concluded that when moms-to-be consume too much vitamin D, the risk of their children developing food allergies after birth may increase.
The survey, completed by the Helmholtz Center for Environmental Research, was recently published in the journal Allergy. We’re often told that most of us are not getting enough vitamin D, which helps strengthen bones and protects the body against infections. The researchers used samples from a cohort of 622 mothers and their 629 children. The vitamin D levels were tested in the pregnant mothers and also in the cord blood of the recently born children. Questionnaires were also used to gather information about the occurrence of food allergies during the first two years of the children’s lives.
In cases where expectant mothers had a low vitamin D level, the occurrence of food allergies among their two-year-old children was more rare compared to cases where the expectant mothers had a high vitamin D level. This finding signaled to researchers that a high vitamin D level in pregnant women may be associated with a higher risk of their children developing a food allergy during childhood. These children were found to have a high level of susceptibility to food allergens such as eggs, milk protein, wheat flour, peanuts, and soybeans.
Vitamin D levels are also affected by exposure to sun, in addition to by diet. The occurrence of food allergies is also affected by many other factors, and not just the level of vitamin D. Based on this finding, researchers advise pregnant women not take vitamin D supplements. If you or a friend is expecting a child, consult your doctor about this new finding.
