BEIJING, Jan. 8 (Xinhuanet) – The kids whose mothers eat nuts regularly during and after pregnancy are less likely to develop nut allergies, according to a research published in the journal JAMA Pediatrics as quoted by media reports Wednesday.
The prevalence of childhood peanut allergies has been rising in the United States in recent years. In 1997, 0.4 percent of children were affected by peanut allergies while the rate had tripled to 1.4 percent in 2010, according to the research report.
Researchers followed 8,205 children who were born between 1990 and 1994 and whose mothers reported their diets before, during and after pregnancy.
By 2009, 140 of the children studied then, or 1.7 percent, had developed allergies to peanuts or tree nuts, including walnuts, almonds, pistachios, cashews, pecans, hazelnuts, macadamias and Brazil nuts.
The result indicates that as long as the mothers aren't allergic to nuts, eating five or more servings a week seem to give their children a higher tolerance for nut allergens, said the researchers.
