“Children appear to be less at risk for developing peanut or tree nut allergies if their mothers are not allergic and ate more nuts during pregnancy,” according to a study published today in JAMA Pediatrics. And although this doesn’t mean that you need to run out for the peanut brittle the minute you’re pregnant, it may mean we can reassure pregnant women that if they have no allergies themselves, what they eat during pregnancy should contain nuts, among other things.
As you’ve likely heard, children with peanut allergies have more than tripled in the United States this last 15 years. Food allergies affect 1 in 13 children in the United States and up to 40% of children have had a life-threatening or severe reaction. Any family with a food-allergic child will tell you this is a BIG deal.
The rapid rise of food allergies is incompletely understood, but more and more research suggests that waiting to introduce “high allergy” foods (traditionally thought of as peanut, egg, or shellfish for example) may have actually caused more allergies than prevented them. As this was being discovered this last decade or so, flip-flopping recommendations on what to eat ourselves when pregnant and what to feed our babies have left many of us confused.
New recommendations really encourage introduction of a variety of foods, including nuts, eggs, shellfish, wheat, and soy within the first year of life. The theory is that early introduction of the components of these foods allow a child’s developing body to create a tolerance to them, thus potentially avoiding any allergy or reaction to them later on.
