Expecting a baby, and craving peanuts; feel free to munch away.

In fact, a new study suggests that expecting mothers, who snack on peanuts and trees nuts during their pregnancy, can lower their children's chances of having peanut allergies, according to NBC News.

In the study, published Monday in the Journal of the American Medical Association Pediatrics, a team of physicians from the Boston Children's Hospital, found that soon-to-be mothers who ate nuts more than five times a month, lessen their child's risk of nut allergies, compared to kids whose mothers chose not to indulge in the snack.  

"In women who ate peanuts and tree nuts more than five times a week, they had children that had a 30 percent reduction in the risk of developing peanut and tree nut allergies," Doctor Michael Young of Boston Children's Hospital and lead author of the study noted.

In the latest study, researchers examined the medical records of 8,205 children and the obtained the dietary information for their mothers during pregnancy. Researchers found that 308  children were born with food allergies, including 140 who were allergic to peanuts, such as almonds, brazils, cashews, hazelnuts and pistachios.

NBC also reported that less than 1.5 percent of children, whose mother's ate less than one serving of peanuts per month, while they were pregnant, did have nut allergies. The expectation to the study was children whose mother's already had peanut allergies themselves.

"We can't say with certainty that eating more peanuts during pregnancy will prevent peanut allergy in children," Young said."But we can say that peanut consumption during pregnancy doesn't cause peanut allergy in children."

NBC reported that earlier studies tried to prove children whose mothers consumed peanuts during pregnancy did not show any reaction to peanuts. Individuals who consume peasants, but are allergic can go into anaphylactic shock.

Young told CNN, that the study is the first to help prove that mothers who consume peanuts, while pregnant, can "help build up a baby's tolerance to them after birth," based on a study published in medical journal JAMA Pediatrics.

"Our study supports the hypothesis that early allergen exposure increases the likelihood of tolerance and thereby lowers the risk of childhood food allergy," said Study leader Dr Lindsay Frazier, of the Dana-Farber Children's Cancer Center in Boston.

According to the Daily Mail, Dr Ruchi Gupta, of the Northwestern University Feinberg School of Medicine in Chicago and an expert on food allergies and asthma, said they current study prove that women should not change their diets during their pregnancy.

"Certainly, women who are allergic to nuts should continue avoiding nuts," Gupta said in an editorial accompanying the new study. "Pregnant women should not eliminate nuts from their diet as peanuts are a good source of protein and also provide folic acid, which could potentially prevent both neural tube defects and nut sensitisation."

However, Young, an immunologist at Boston Children's Hospital, noted that women who are pregnant should not begin eating peanuts, just to prevents their children from getting nut allergies.  

"The take-home message is that the previous concern or fears of the ingestions of nuts during pregnancy causing subsequent peanut or nut allergy is really unfounded," said Young, according to NBC News.
