Times have changed. New study brings new understanding.

We used to believe that by avoiding peanuts early in life we could decrease the rate of peanut allergy later in life. When in fact, the landmark LEAP TRIAL showed that babies at high risk of developing a peanut allergy who were introduced to peanut-containing foods early in life were about 80% less likely to develop a peanut allergy by age 5.

Introducing and continuing to feed babies ground peanuts may reduce the risk of developing a peanut allergy.

Researchers found that babies at high risk of developing a peanut allergy who were fed 2 grams of peanut protein, at least three times a week, for five years starting at the age of 4-11 months, were about 80% less likely to develop a peanut allergy by age 5.

Age: High-risk infants at 4-11 months
Feed: 2 grams of peanut protein, 3x a week
Duration: The first 5 years of life
Benefit: Reduced the risk of developing peanut allergies

In the LEAP Trial, children who ate peanut-containing foods beginning early in life were significantly less likely to develop peanut allergies than those who avoided peanuts.

In the study only 0.4% of children who ate peanut-containing foods had developed a peanut allergy

…Compared to more than 13% among those who avoided peanuts.
