Dogs May Reduce Allergies and Obesity in Babies
For the past couple of decades researchers have been looking at the role that pets, especially dogs, have to play in rates of allergies in children. Many have found that, what is being termed the hygiene hypothesis, is indeed correct, meaning that a little dirt early in life helps to stave allergic diseases, including obesity.
A new study by Anita Kozyrskyj a pediatric epidemiologist of the University of Alberta in Edmonton, Canada, found further evidence of this dog-human linkage and how this lessens the development of everything from obesity to asthma.
Starting in 2013 she wondered if she could pinpoint what and how this might be happening. Her team collected fecal samples from 4-month-old infants in the Canadian Healthy Infant Longitudinal Development (CHILD) pilot study. Of the 24 respondent infants, 15 lived in house with at least a dog or cat.
