London - The idea that eating peanuts early as a child is the best way to avoid a peanut allergy has been confirmed in a new research study.
Last year a study a study concluded that early exposure to peanut products cut the risk of allergy by 80 percent (see: New England Journal of Medicine "Randomized Trial of Peanut Consumption in Infants at Risk for Peanut Allergy.") This was important research because peanut allergies can pose considerable risks. The range of symptoms covers: itchiness, urticaria, swelling, eczema, sneezing, asthma, abdominal pain, drop in blood pressure, diarrhea and cardiac arrest. The cause is a hypersensitivity reaction to dietary substances that triggers an extreme reaction of the body's own immune system.
The 2015 study found if children eat peanut snacks within the first 11 months of life then they show no symptoms of an allergy developing up to the age of five (when they continue to eat occasional peanut snacks).
Building on this, a new study demonstrates "long-lasting" peanut allergy protection can be sustained, even if subjects stopped eating peanut products after one year. The new study was conducted at King's College London.
The new study used the same test subjects as those reported in the 2015 trial. Here, some of the test subjects on reaching the age of five, who had been exposed to peanut products as children, abstained for one year. It was found that by six years of age there was no significant increase in allergic reaction after 12 months of avoiding any peanuts or peanut based products.
Discussing the results with BBC Science, lead author Professor Gideon Lack stated: "The research clearly demonstrates that the majority of infants did in fact remain protected and that the protection was long-lasting."
The new study is also published in the New England Journal of Medicine, and it is headed "Effect of Avoidance on Peanut Allergy after Early Peanut Consumption."
