Parents, do not be afraid to suck.

It is the advice of new research that, when unpleasant – may literally, depending on where the union is released – protect children from developing allergies.

The findings are presented at the annual meeting of the American College of Allergy, Asthma and Immunology, held November 19th in Seattle.

Sound Gross

Maybe. But mothers who clean pacifiers by sucking them have infants with a lower allergic response, according to research by Henry Ford Hospital in Detroit.

The study interviewed 1

28 mothers over an 18 month period and asked how they cleaned their children’s pacifiers. Of the 74 children whose children used one, 72 percent said they washed them by hand, 41 percent said they were sterilized and 12 percent said they spotted the cleaning of the child.

Scientists found that children whose mothers spit-cleansed pacifiers had lower levels of IgE, an antibody associated with allergic reactions. Elevated IgE levels typically indicate a higher risk of allergies and allergic asthma .

“We found that parental suckers were linked to suppressed IgE levels that began about 10 months and continued for 18 months,” said Dr Edward Zoratti, an allergist and co-author. “Further research is needed, but we believe that the effect may be due to the transmission of health-promoting microbes from the mother’s mouth.”

You follow it? The spread of bacteria from the parents’ mouth appeared to increase the child’s immune system.

Research is not the cause and effect, and it is unclear whether the lower IgE production seen among these children continues in recent years.
