Eat Your . . . Dirt?

Yep, it can be good for you!

An article in the NYTimes summarizes the "hygiene hypothesis," namely:

that organisms like the millions of bacteria, viruses and especially worms
that enter the body along with “dirt” spur the development of a healthy
immune system. Several continuing studies suggest that worms may help to
redirect an immune system that has gone awry and resulted in autoimmune
disorders, allergies, and asthma.

These studies, along with epidemiological
observations, seem to explain why immune system disorders like multiple
sclerosis, Type 1 diabetes, and inflammatory bowel disease, asthma and
allergies have risen significantly in the United States and other developed
countries.

Indeed, the article notes that research with mice has shown that the introduction of worms into the digestive system actually decreases the effects of many of those diseases.

So, when is dirt "dirty" and when is it clean? The article's experts suggest:

“I certainly recommend washing your hands after using the bathroom, before
eating, after changing a diaper, before and after handling food,” and whenever
they’re visibly soiled, [Dr. Ruebush] wrote. When no running water is available and
cleaning hands is essential, she suggests an alcohol-based hand sanitizer.

Dr. Weinstock goes even further. “Children should be allowed to go
barefoot in the dirt, play in the dirt, and not have to wash their hands when
they come in to eat,” he said.

And get some pets.

Who knew staying healthy could be so much fun? And so dirty . . .
