Health Secrets of the Amish
*Children who grew up on small farms were between one-half and one-third less likely to have hay fever and asthma, compared with non-farming children living in the same rural areas. European scientists identified livestock, particularly dairy cows, fermented feed and raw milk consumption as protective in what they eventually called the “farm effect.” Many scientists argued that the abundant microbes of the cowshed stimulated children’s immune systems in a way that prevented allergic disease.
Then, a few years ago, researchers found an American example of the phenomenon: the Amish. Children from an Amish community in Indiana had an even lower prevalence of allergies than European farmers, making them among the least allergic subgroup ever measured in the developed world.
Now a study released on Wednesday in The New England Journal of Medicine advances the research. The authors did something new and important: They found a suitable comparison group for the Amish in another farming community, the Hutterites. The two groups share genetic ancestry. Both descend from German-speaking stock. But unlike the Amish, the Hutterites, who live in the upper Midwest, are as allergic as your average American.'>>>
