According to a new report, children born to women who ate vitamin D-rich foods during pregnancy have a 20% lower risk of hay fever. Dietary sources of vitamin D include fish, eggs, dairy products, mushrooms, and cereals. Vitamin D is believed to benefit the immune system, and researchers are interested in its potential role in reducing the risk of asthma and allergies. Study leader Dr. Supinda Bunyavanich comments, “This study may influence nutritional counseling and recommendations to expectant moms to include vitamin D-rich foods in their diets.”
