Dog ownership tied to lower Crohn's risk
Sorry, cat people and only children: Having a dog as a toddler and growing up in a large family are two things linked to a significantly lower chance of getting Crohn's disease later in life, according to a new study.
Turpin and colleagues looked at other things in the environment – including living on a farm, drinking unpasteurized milk or well water, and growing up with a cat – but they did not have a significant link to a higher risk. The study included 4,289 healthy first-degree relatives of people diagnosed with Crohn's disease. They provided urine, blood, and stool samples and did surveys about environmental exposures at different stages of life.
"Our study also shows that just by living with a dog, it impacts your gut microbiome composition, which may have an impact on the immune response later in life."
