Parents, do not be afraid to suck.

These are new research tips that, although disgusting – perhaps literally, depending on where the nipple is missing, can protect babies from developing allergies.

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

Sound gross?

May be. According to researchers from the Henry Ford Hospital in Detroit, mothers who clean pacifiers, suck them, have children with a lower allergic response.

The study surveyed 128 mothers over an 18-month period and asked how they clean their babies' soothers. Of the 74 whose children used one, 72 percent said they washed them by hand, 41 percent said they were sterilized, and 12 percent said they cleaned the baby's umbilical cord.

Scientists found that babies who had urine-free nipples had lower levels of IgE, antibodies associated with allergic reactions. Elevated levels of IgE usually indicate a higher risk. allergies and allergic asthma,

“We found that sucking the parental nipple was associated with suppressed IgE levels starting after about 10 months and lasted after 18 months,” said Dr. Edward Zoratti, an allergist and co-author of the study. "Further research is needed, but we believe that the effect may be caused by the transfer of healthy microbes from the oral cavity."

Do you follow this? It was found that the spread of microbes from the oral cavity enhances the immune system of the child.

The study does not prove cause and effect, and it is unclear whether the lower production of IgE continues among these children in subsequent years.
