If you worry about food allergies, listen up. In a new study coming out of Australia, researchers have discovered that babies might develop allergies before they're even born.
After examining blood samples from 12 children with allergies, doctors from the Murdoch Children's Research Institute in Melbourne were able to see that certain babies were actually born with significant genetic differences, meaning that they didn't develop them after birth.
The report is bringing up the age-old nature vs. nurture battle. By studying the babies' epigenetics (the change in gene expression when they're reacting to different environmental factors), the doctors were able to narrow down the origin of their allergic genes. And it's causing plenty of questions for parents.
