Mothers who eat nuts during pregnancy may prevent the unborn fetus from developing a nut allergy, a study has shown.

Scientists analysed data on more than 8,000 American children, including 140 who had peanut or tree nut (P/TN) allergies.

Those with mothers who ate nuts five times a week during pregnancy emerged as the lowest P/TN allergy risk.

US lead researcher Dr Michael Young, from Boston Children's Hospital, explained:

"Our study showed increased peanut consumption by pregnant mothers who weren't nut allergic was associated with lower risk of peanut allergy in their offspring.

"Assuming she isn't allergic to peanuts, there's no reason for a woman to avoid peanuts during pregnancy."
