Children born in the fall are also three times more allergic to common foods like milk and eggs than babies born in the summer. Scientists believe that high levels of pollen during the time of pregnant mothers are the main cause of food allergies.

After mothers were 3 months pregnant, the fetus in the womb began to produce antibodies against the pollen when mothers inhaled. Scientists say antibodies against pollen like immunoglobin E are involved in food migration. However, why immunoglobin E causes food allergy has not been explained.

Dr Kaisa Pyrhönen, of the University of Oulu Health Sciences Institute, said: " In the womb, the fetus can produce all kinds of antibodies against pollen. Therefore, children of mothers Pregnancy in season with more pollen is more prone to food allergies '.

Scientists conducted studies with 5,920 children born between 4/2001 and 3/2006 in a region in Finland. As a result, the team found that 961 of these children now have food allergies.

A previous study also found that children born in the fall or winter often suffer from eczema and wheezing due to higher levels of anti-allergy antibodies in the blood than those born in spring and season. summer.

However, some other studies suggest that summer-born children are more prone to ADHD disorders and those born in the spring have a higher risk of multiple sclerosis when they grow up.
