Sucking on your baby’s pacifier may protect them from allergies

According to findings presented at the American College of Allergy, Asthma, and Immunology conference, the incidence of shellfish allergy has grown by 7 percent, tree nuts by 18 percent, and peanuts by 21 percent.

This simple procedure allows to prevent the development of allergies and asthma in kids, according to Science Daily.

Over half (58 per cent) of the mothers interviewed reported that their child was now using a dummy.

'It is unclear whether the lower IgE production seen among these children continues into later years'.

The researchers tracked the babies for 18 months and noted that changes in some babies' levels of IgE antibody started when they were around 10 months old. The researchers checked the babies' IgE levels at birth, 6 months and 18 months of age. The conclusion seems to be supported by a previous study published in 2013 by Swedish researchers, who likewise found an association between parents sucking on their baby's pacifiers and a reduced risk of allergy development. The study found that parents who suck on their baby's pacifier to clean it might have been boosting their baby's health.

"Parental pacifier sucking may be an example of a way parents may transfer healthy microorganisms to their young children", she said.

According to new USA research being presented at the American College of Allergy, Asthma and Immunology (ACAAI), the children of mothers who sucked on their pacifiers in order to clean them had a lower allergic response than children whose mothers cleaned the soothers either by sterilization or hand washing.

However, lead author of the study Dr Eliane Abou-Jaoude said further research was necessary to prove the dummy-sucking practice was responsible for the lowered allergic responses in children.

"There are lots of commensal or good bacteria in the microbiome that may really help your baby develop a tolerance to it as they age", notes Dr. Wendy Sue Swanson of Seattle Children's Hospital. Of that group, 41 per cent of respondents reported cleaning their child's pacifier by sterilizing it, 72 per cent said they hand washed it, and 12 per cent said they sucked on it themselves. "But that doesn't mean that if you have high IgE, you're definitely going to have allergies".

IgE is a type of antibody that is produced when the immune system overreacts to an allergen, which can then cause an allergic reaction. Additional analyses indicated the differences were first seen at about 10 months.
