Some time ago several studies emerged that related the consumption of nuts during pregnancy with an increase in childhood asthma and other allergies, especially these foods, by children. Now new research denies that nuts during pregnancy are related to childhood allergy.
The incidence of cases of childhood allergy to nuts is significantly lower (five times less) among those children whose mothers had taken these foods during pregnancy (more than five times a month) than among the children of mothers who had avoided them.
The study has been carried out by researchers at the Boston Children's Hospital and the data is published in the journal JAMA Pediatrics. Its title is "Prospective study of peanut and nut consumption during, before and after pregnancy and the risk of allergy in their offspring".
The study included 10,907 children whose mothers had registered their diet during their pregnancy and subsequently recorded cases of childhood allergies to nuts developed by some of these children, checking the diet their mothers had followed.
It was found that the more nuts the mothers consumed, the lower the risk to their children. This fact supports the hypothesis that early exposure to the allergen increases the likelihood of tolerance and therefore decreases the risk of food allergies in childhood.
However, the researchers point out that additional studies are necessary to confirm these results. For now, it seems that There is no reason to avoid nuts during pregnancy, since it is also a healthy snack and one of the foods that can not be missing in pregnancy, always, of course, that the future mother is not allergic to them.
