Here is a fascinating health statistic from the Amish world.

Data from two nearly identical communities, the Amish of Indiana, and Hutterites of South Dakota, show the following:

The prevalence of asthma in the Amish of Indiana is low at 5.2% as compared to 21.3% in Hutterite schoolchildren of South Dakota; likewise the prevalence of allergic sensitization is 7.2% versus 33.3%.

The lifestyles of the two groups are nearly identical except for one thing...farming practices. The Hutterites use industrialized farming methods, the Amish use old world, natural farming.
