Young mothers, do not get rid of your pet: it could prevent your baby from having allergies and becoming obese!

By modulating the composition of newborns’ intestinal microbiota, pets reduce the risk of later developing an allergy or obesity in adulthood.


This is the astonishing conclusion reached by Canadian researchers who examined 746 newborns. Their study, published in the journal Microbiome, shows that pre- and/or post-natal exposure to furred animals increases the presence of Oscillospira Ruminococcus bacteria in the microbiota of babies, germs which are known to reduce the risk of obesity and allergy.

During pregnancy, being surrounded by pets would also be an asset: the presence of streptococci would be decreased, reducing the risk of Streptococcus B infection. These animals would enrich the microbiota of the future baby and, consequently, reduce their propensity for atopic and metabolic diseases.

The presence of a pet during pregnancy or after the arrival of the baby in the home requires a few precautions, but it is not necessary to part with your pet.
