Bad News About Nuts During Pregnancy

A new study just published in the American Journal of Respiratory and Critical Care Medicine suggests that pregnant women who eat nuts or nut products like peanut butter daily during pregnancy increase their children's risk of developing asthma by more than 50 percent over women who rarely or never consume nut products during pregnancy.

Don't worry just yet. Research in the area of allergenic foods during pregnancy has been contradictory and inconclusive. The main thought behind it being that the allergens present in foods like nuts cross the placenta and cause fetuses that are exposed to become sensitized to certain allergens.

John E. Heffner, M.D., past president of the American Thoracic Society made a statement in response to the research, "These findings emphasize the critical important of additional investigations into the environmental exposures for both mother and child that underlie the pathogenesis of asthma... It is important, however, to emphasize that such associations do not confirm a causative linkage."
