How Allergies in Infants are Impacted by Diet During Pregnancy?

In a longitudinal study of pregnant women across US, many of the women avoided certain allergenic foods to prevent food allergies in infants.

Pregnant women in the United States avoided certain targeted food items during pregnancy to prevent future food allergies in infants. A longitudinal study of the pregnant women was conducted by the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention.//

About 4,900 pregnant women completed the Infant Feeding Practices Study II prenatal questionnaire from May 2005 to June 2007. The study tracked 2,000 pregnant women from the third trimester of pregnancy and their infants through the first year of life. A small percentage of women said they had consumed fewer allergens during pregnancy to stave off food allergies in their newborns, according to a poster Dr. Robbins presented during the American College of Asthma Allergy and Immunology 2018 Annual Scientific Meeting. While their numbers were small, most of these women reported giving up major allergens like nuts, milk or eggs during pregnancy, including:

‘Many of the infants born to these mothers were likely to have problems with food in 4 months but, later never experienced allergy towards food.’

• 144 (2.9 percent) reported restricting their diet in some way to prevent future food allergies in their offspring

• 84 women (1.7 percent) ate fewer nuts

• 15 women (.3 percent) ate fewer eggs and

Monosodium Glutamate (MSG) Allergy
Monosodium glutamate or MSG is used to enhance flavor especially in Chinese cuisine. Individuals allergic to MSG experience headache and nausea.

• 2 women (.04 percent) ate/drank consumed less dairy/milk.

"At the time the survey was conducted, few pregnant women in this large data set said they gave up certain foods with the express aim of avoiding a food allergy in their babies," Dr. Robbins says. "However, mothers who had an older child with a food allergy or who had food allergies themselves had significantly higher odds of trying this food avoidance strategy."

Despite the diet changes, infants born to these expectant mothers were twice as likely to experience problems with food at age 4 months - though not at age 9 months or 12 months. And these infants were no more likely to be diagnosed with a food allergy.

According to the FDA, millions of Americans suffer a food allergy each year. Reactions can range from mild to life-threatening and can begin soon after eating a problematic food item or an ingredient from that food. Among the most common allergenic foods are milk, eggs, fish, shellfish, tree nuts, peanuts, wheat and soybeans.

Diet For Anemia In Pregnancy And What Foods To Avoid
A modified diet rich in Folate, Vitamin B12 and Iron is essential for the rapid rise in hemoglobin level.

"We really need to know more about how often targeted food avoidance occurs among U.S. pregnant women who have a family history of food allergies," Dr. Robbins adds. "We hope to learn what factors into these women's decision-making as well as why many of them settled on food avoidance as a potential strategy to try to prevent food allergy in their infants."
