Children who live on farms that produce milk run one-tenth the risk of developing allergies as other rural children.
According to researchers at The University of Gothenburg, Sweden, pregnant women may benefit from spending time on dairy farms to promote maturation of the fetal and neonatal immune system.
The occurrence of allergic diseases has risen dramatically in Western societies. One frequently cited reason is that children are less exposed to microorganisms and have fewer infections than previous generations, thereby delaying maturation of the immune system.
A study by researchers at Sahlgrenska Academy, University of Gothenburg, monitored children until the age of three to examine maturation of the immune system in relation to allergic disease. All of the children lived in rural areas of the Västra Götaland Region, half of them on farms that produced milk.
Lower risk of allergy
The study found that children on dairy farms ran a much lower risk of developing allergies than the other children.
“Our study also demonstrated for the first time that delayed maturation of the immune system, specifically B-cells, is a risk factor for development of allergies,” says Anna-Carin Lundell, one of the researchers.
Need for additional studies
Children with an allergic disease at the age of 18 and 36 months had a higher percentage of immature B-cells in their blood circulation at birth and during the first month of life. Additional studies are needed to corroborate the correlation between delayed B-cell maturation during the neonatal period and the risk for subsequent development of allergies.
The Gothenburg researchers will start off by examining children as they turn eight.
“We need to identify the specific factors on dairy farms that strengthen protection against allergies and appear to promote maturation of the immune system as early as the fetal stage,” Ms. Lundell says.
The article High proportion of CD5+ B-cells in infants predicts development of allergic disease was published online in The Journal of Immunology on June 13.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
