The Amish are remarkably resistant to allergies, with only 7% of Amish children testing positive for common allergens, making them one of the least allergic populations in the developed world, unlike the general U.S. population and other traditional farming communities.
The Amish are nearly immune to allergies, with only 7% of Amish children showing allergic responses compared to over 50% of the general U.S. population, making them a mystery to experts studying allergies.
A study led by researchers at the University of British Columbia and BC Children's Hospital has found that several major childhood allergies, including eczema, asthma, food allergy, and hay fever, may have a common origin in the gut microbiome. The study examined the gut microbiota of 1,115 children from birth to age five and identified a bacterial signature associated with the development of these allergies. Factors such as antibiotic usage in the first year of life were found to increase the risk of allergies, while breastfeeding for the first six months was protective. The findings could lead to methods of predicting and preventing childhood allergies.
