#1 Amish farm kids remarkably immune to allergies: study05-06-2012, 11:18 AM

NEW YORK (Reuters Health) - Amish children raised on rural farms in northern Indiana suffer from asthma and allergies less often even than Swiss farm kids, a group known to be relatively free from allergies, according to a new study.
"The rates are very, very low," said Dr. Mark Holbreich, the study's lead author. "So there's something that we feel is even more protective in the Amish" than in European farming communities.
What it is about growing up on farms -- and Amish farms in particular -- that seems to prevent allergies remains unclear.
Researchers have long observed the so-called "farm effect" -- the low allergy and asthma rates found among kids raised on farms -- in central Europe, but less is known about the influence of growing up on North American farms.
Holbreich, an allergist in Indianapolis, has been treating Amish communities in Indiana for two decades, but he noticed that very few Amish actually had any allergies.
As studies on the farm effect in Europe began to emerge several years ago, Holbreich wondered if the same phenomenon might be found in the United States.
He teamed up with European colleagues to compare Swiss farming children and non-farming children to Amish kids in Indiana.
Amish families, who can trace their roots back to Switzerland, typically farm using methods from the 1800s and they don't own cars or televisions.
The researchers surveyed 157 Amish families, about 3,000 Swiss farming families, and close to 11,000 Swiss families who did not live on a farm -- all with children between the ages of six and 12.
They found that just five percent of Amish kids had been diagnosed with asthma, compared to 6.8 percent of Swiss farm kids and 11.2 percent of the other Swiss children.
Similarly, among 138 Amish kids given a skin-prick test to determine whether they were predisposed to having allergies, only 10 kids -- or seven percent -- had a positive response.
In comparison, 25 percent of the farm-raised Swiss kids and 44 percent of the other Swiss children had a positive test, the researchers report in the Journal of Allergy and Clinical Immunology.
The study did not determine why the kids who grew up on farms were less likely to develop asthma and allergies, but other research has pointed to exposure to microbes and contact with cows, in particular, to partially explain the farm effect (see Reuters Health story of May 2, 2012).
Drinking raw cow's milk also seems to be involved, Holbreich said.
The going theory is this early exposure to the diverse potential allergens and pathogens on a farm trains the immune system to recognize them, but not overreact to the harmless ones.
As for why the Amish kids have even lower allergy and asthma rates than the other farming kids, "that piece of the puzzle we really haven't explained," Holbreich told Reuters Health.
He speculated that it could be at least partly a result of the Amish having larger families or spending even more time outside or in barns than people on more modern working farms.
Dr. Corinna Bowser, an allergist in Cherry Hill, New Jersey, said there's also a possibility that inherited factors could play a role.
"The Amish are still of a limited genetic pool, I would assume, because they're much more segregated than the Swiss kids are," she told Reuters Health.
Holbreich said upcoming studies will further investigate the differences between the farming groups, with an eye toward designing possible interventions.
For instance, pregnant mothers or young children could be exposed to the mysterious factors that seem to protect farm kids as a preventive treatment, he explained.
"The goal is to try to find a way to prevent this allergy and asthma epidemic that western populations are facing," Holbreich said.

Who would have thought that raising kids in climate controlled rooms away from any natural particulate matter would increase susceptibility to allergies,duh!
Sometimes it seems with some mothers it is trendy to brag about how many allergies their kids have, you aren't cool without at least one alphabet disease to brag about.
This may piss people off when I say it but I think half of allergies are psychosomatic dependent on what current allergy is trending, suck it up and go outside!The difference between pigs and people is that when they tell you you're cured it isn't a good thing.

People have to toughen up a bit. I think all those little antibacterial wipes probably remove so many germs that when a bad one comes along, the person is susceptible.
As far as the Amish go, there's a large community here in Sarasota. I've never seen such healthy looking young people.

Wow. Imagine that. Growing up on a diet of steady work, family love, fresh foods and well founded community standards produces healthy individuals.

I've never been allergic to anything that I know of. I am immune to poison ivy. One time a jellyfish stung and it hurt, after that it seemed like I was immune to them too. Bee stings don't bother me much. I was attacked by a swarm of wasps as a child, and that did hurt. Sumac doesn't bother me.
My cousin (maternal first paternal fourth) who was raised in the same environment I was had asthma as a child, at least they said he did. We now suspect that he has been allergic to bananas for a lot longer than anyone knew, and they played into his entire health picture.
I grew up playing in dirt, fertilizer, corn fields, soy beans, old barns with pigeon crap all over the place, chicken houses, etc...

It is said that branches draw their life from the vine. Each is separate yet all are one as they share one life giving stem . The Bible tells us we are called to a similar union in life, our lives with the life of God. We are incorporated into him; made sharers in his life. Apart from this union we can do nothing.
