It turns out one way to protect babies from developing bad allergies in life is to give them breast milk from Mennonite mothers who grew up on farms.

Yes, that’s for real: a new (peer reviewed!) study published in Frontiers in Immunology found that breast milk from Mennonite moms has a greater abundance in the type of antibodies and other immune systems components that protect babies from common allergies.

“Our findings indicate that that breast milk from old order Mennonite mothers contains higher levels of beneficial antibodies, microbes and metabolites that help to ‘program’ the developing gut microbiota and immune system of their babies,” study coauthor Antti Seppo from the University of Rochester said in a statement?

Not only did Mennonite breast milk contain more allergy-associated antibodies, but it also contained a greater diversity of milk microbes that bolster the developing gut microbiota of babies.
