peanut allergy


A new research has showed that eating peanut products as a baby could cut the risk of allergy.

Last year, a study claimed early exposure to peanut products could cut the risk by 80%.

Now researchers say “long-lasting” allergy protection can be sustained – even when the snacks are later avoided for a year.

Published in the New England Journal of Medicine, the new study looked at 550 children deemed prone to developing a peanut allergy.Peanut allergy study

The latest paper builds on the results of the 2015 research, which was also carried out by King’s College London and marked the first time scientists were able to suggest that exposing children to small amounts of peanut snacks could stave off an allergy.

The new study suggests that if a child has consumed peanut snacks within the first 11 months of life, then at the age of five they can afford to stop eating the food entirely for a year, and maintain no allergy.

The researchers used the same children who took part in the 2015 study – half of whom had been given peanut snacks as a baby while the remainder had been fed on a diet of breast milk alone.

The children taking part in the study were considered prone to peanut allergy, because they had already developed eczema as a baby – an early warning sign of allergies.


A British study suggests that an early exposure to peanut products dramatically cuts the risk of allergy.

Doctors found that exposing at risk infants to peanuts before their first birthday lower the risk of developing a peanut allergy.

Trials on 628 babies prone to developing peanut allergy found the risk was cut by over 80%.

The King’s College London researchers said it was the “first time” that allergy development had been reduced.

Specialists said the findings could apply to other allergies and may change diets around, but warned parents not to experiment at home.

The research team in London had previously found that Jewish children in Israel who started eating peanuts earlier in life had allergy levels 10 times lower than Jewish children in the UK.Peanut allergy risk infants

The trial, reported in the New England Journal of Medicine, focused on babies as young as four months who had already developed eczema – an early warning sign of allergies.

Skin-prick tests were used to identify those who had not yet developed peanut allergy or had only a very mild response.

Children under five should not eat whole peanuts, because of the risk of choking, so half were given a peanut-based snack. The other half continued avoiding peanuts.

The trial indicated that for every 100 children, 14 would normally go on to develop an allergy by the age of five.

This fell by 86% to just two out of every 100 children with the therapy.

Even the children who were already becoming sensitive to peanuts benefited. Their allergy rates fell from 35% to 11%.

Until 2008, at-risk families were told to actively avoid peanut products and other sources of allergic reactions.

The study findings have attracted excited responses from other doctors, and there is speculation similar approaches might work with other allergies, such as egg protein.
