Researchers at the Albert Einstein College of Medicine at Yeshiva University have reviewed the health data of 3,100 children and adolescents and found that a deficiency in vitamin D correlates with many environmental and food allergies.
Interestingly, in a similar examination of 3,400 adults, no link was found between vitamin deficiency and allergies.
The researchers found that kids with low levels of vitamin D tended to be allergic to 11 out of 17 of common irritants. Peanut allergies were 2.4 times more prevalent among this group.
The team noted that the study does not prove that vitamin D deficiency causes allergies, only that there is a correlation. They said it is still important for children to get adequate amounts of the nutrient, which study authors said is about 600 international units (IU) daily.
Bob Livingston, editor of Personal Liberty Digest, takes between 5,000 IU and 10,000 IU of vitamin D per day depending on the time of year.
The National Institutes of Health reports that vitamin D aids in calcium absorption to promote healthy bones. Additionally, it has been shown to regulate cell growth, neuromuscular and immune function as well as reduce inflammation.
Several recent studies have suggested that many Americans are deficient in vitamin D.
