Impact: Health & Welfare Impacts

Description of impact

University of Portsmouth research has led to a change in Department of Health guidelines on maternal consumption of peanut during pregnancy/breastfeeding.

Who is affected

Healthcare Professionals; Public


Department of Health guidelines until 2009 advocated the avoidance of peanut in allergic families. However evidence base for this advice was poor and the advice was adopted by families regardless of their allergy status leading to significant constraints on their lifestyles. Our research revealed that peanut allergy is not associated with maternal peanut consumption, and that there was no need for pregnant women to avoid peanut during pregnancy. On the basis of our research DoH concluded that previous guidance was inappropriate and it was thus withdrawn.
