Vitamin D-rich Foods During Pregnancy May Cut Your Kid’s Allergy Risk – Health Newsline

allergyEating vitamin D-rich diet during pregnancy may potentially reduce the risk of development of allergies in children, finds a new study.

In an American study, led by researchers from the Icahn School of Medicine at Mount Sinai, taking vitamin D containing diet in substantial amount during pregnancy could protect a child from developing allergies.

The study links consumption of vitamin D containing foods, not vitamin D supplements, to reduced allergy risk in children.

The study authors stressed that consuming foods naturally containing the vitamin such as fish, eggs, dairy products, mushrooms, and cereals is beneficial for reducing baby’s allergy risk rather than relying on dietary supplements, which they found ineffective at reducing the allergy risk.

The study findings revealed that a higher consumption of vitamin D-rich foods in pregnancy reduces the risk of childhood asthma by 20 percent.

Lead study author Dr Supinda Bunyavanich said: “Expectant mothers have questions about what they should eat during pregnancy, and our study shows that it’s important to consider the source of nutrients in a mother’s diet.”

To arrive at their conclusion, the researchers enrolled 1,248 US mothers and their children, and followed them from the first trimester of pregnancy until their children reached around seven years old.

Both mother and child underwent allergy tests during pregnancy, at birth and at school age, with mothers also filling in a food frequency questionnaire inquiring about their food intake during pregnancy. Tests of serum 25(OH)D levels were also carried out in both mothers and school-age children.

The results showed that children of women who had a higher-intake of foods majorly containing vitamin D during pregnancy were less likely to develop allergies by school age.

During the study period, women drank an eight ounce serving of milk every day or consumed the equivalent amount of vitamin D from some other source of food.

While the intake of higher quantities of foods rich in vitamin D during pregnancy resulted in children with 20 percent less likely to develop hay fever at school age, ingesting supplemental vitamin D did not appear to curb the child’s risk for developing allergies, the study noted

Vitamin D, sometimes called the Sunshine vitamin, is known to modulate the immune system, with its role in asthma and allergies specifically garnering interest.

Dr Bunyavanich said: “This study may influence nutritional counselling and recommendations to expectant moms to include vitamin D-rich foods in their diets.”

The full study is published in The Journal of Allergy and Clinical Immunology.
