Researchers revealed through new study that babies conceived in early spring or in late winter are more at risk of anguish food allergies. The casement of time between April and May when babies in the womb attain eleven weeks is associated with twice the rate allergies to ordinary foods like milk and eggs.

They found that eleven percent of babies whose eleventh week of growth in the womb was in April or May were more prone to suffer allergies. In comparison to it babies whose growth of eleventh weeks was in December were only six percent prone to allergies.
Tests on pollen levels over the study period showed that levels of birch and alder pollen peaked during April and May, reported the study published in the Journal of Epidemiology and Community Health. Increased rates of asthma and allergies over the last thirty years have been accredited to a variety of triggers like excessively-clean lifestyles, diet and untimely use of antibiotics.
They found an upper occurrence of optimistic findings in food allergy test among babies born in October or November than those born in other months, explained lead researcher Dr Kaisa Pyrhonen from Oulu University Hospital in Finland.
