Peanut allergies strike fear into the hearts of many parents, my patients included.

It’s an understandable concern, as peanut allergy is one of the most common food allergies in the United States, affecting up to 3 percent of all children. Rates have risen steadily over the past 15 years.

Fortunately, new research published earlier this year may provide an answer to preventing the development of peanut allergies in children. Although it may sound terrifying to some parents, it starts with introducing infants to the legumes early and often.

The British study published in the New England Journal of Medicine showed that early introduction of peanuts – between the ages of 4 months and 11 months – in infants at high risk for the development of this allergy actually helps to prevent it.

Until recently, pediatricians were taught to tell parents to hold off on the introduction of certain foods if their child is at high risk for an allergy. So the findings from this randomized trial truly represent a dogmatic shift in prevention of peanut allergies for doctors and parents. ​

In this study, when children were given peanuts from an early age, only 3 percent developed an allergy compared to a whopping 17 percent of those who avoided peanuts for five years. According to this data, you would only have to give peanuts to about seven children at an early age to prevent one child from developing a peanut allergy!

This clinical trial provides excellent evidence that it is safe and effective to change our recommendations and support the early introduction of peanuts. The next practical question for parents: When is my child ready to eat peanuts?

Before feeding your child peanuts, it is imperative to make sure he or she is ready to eat solid foods. Here are signs of food readiness:

  • A child is at least 4 months of age.
  • She sits with support.
  • He holds his head up well.
  • She shows interest in eating – often parents say children get fussy and want to grab their food.
  • He opens his mouth for food.

Additionally, when it comes to purchasing peanuts for your child, remember to choose wisely. Some helpful tips:

  • Purchase a pure peanut butter – preferably with nothing else but peanuts on the label’s ingredients list. Avoid added sugars, fats, salt and chocolate.
  • Try out powdered peanuts, which are lower in fat but easy to mix with foods.
  • For older children who are ready for textures, grind or finely chop the peanuts.
  • Never introduce whole peanuts until after the age of 4 due to the choking risks.

The study gave the equivalent of three teaspoons of peanut butter per week. While it’s not yet known if you need to give this much or if it can be less, 3 teaspoons ​ per week serves as a good rule of thumb to follow.
