A new study published in the journal Clinical & Experimental Allergy says that infant gut bacteria, as examined through stool samples, could be a predictor of common allergies including food allergies.
The study was conducted by researchers from the University of Alberta and the University of Manitoba in Canada and involved 166 different infants at the age of 3 months and again at the age of 1.
Study aims to grow in size after initial results
The infants were part of a wider group of studies in the Canadian Healthy Infant Longitudinal Development Study (CHILD) involving more than 3,500 families and their babies across Canada.
The researchers in this study found that infants with fewer gut bacteria at 3 months of age are more likely to become sensitized to foods such as milk, eggs, and peanuts by the time they’re 1 years old. The study’s conclusion says it’s possible that this could be used as a way to easily test young children for allergy risk. To accomplish this, the researchers plan to follow up on the study when the children reach three and five years of age and include up to 2,500 more people in the research.
