The basic idea is that
with zonulin, a fairly large (47 kDa) protein produced in the gut, should not be able to pass into the bloodstream under normal conditions.
The protein called gliadin which is found in gluten interferes
with zonulin's function, which leads to increased hyper - permeability, a condition known as leaky gut.

«In these people, gliadin, one of the components of gluten, stimulates the release of a substance called
zonulin when it makes contact
with the cells of the small intestine,» says nutritionist and naturopath Sarah Luck.
Studies have shown the foods that contain gluten interfere
with the functioning of a specific protein in your gut known as
zonulin, which wreaks havoc on the intestines.
For those of us
with celiac disease, ingesting even trace amounts of gluten can lead to an increase in intestinal permeability (also known as leaky gut) through the action of a protein called
zonulin.
However, two main triggers have been identified to produce
zonulin and are thought to contribute to increases in intestinal hyperpermeability in everyone who has a gut wall, not just people
with autoimmune disease.
With evidence that the intestines naturally mediate their own permeability by releasing
zonulin from the gut wall, researchers were finally able to gain a deeper understanding of what causes a leaky gut.

Zonulin
Celiac disease patients have higher concentrations of serum
zonulin during the acute phase of disease compared
with their healthy counterparts, and also have over-expressed CXCR3, the intestinal receptor for gliadin (Fasano, 2011).
For example, a close look at the data from one study finds that only 42 percent of the patients
with type 1 diabetes had an elevated serum
zonulin level (defined as 2 standard deviations above the control group mean)(13).
Fecal
zonulin has also been explored as a marker, but the stability of this marker over time is unknown and it may very likely mirror the fluctuations seen
with blood
zonulin.
First, in many of these studies I listed in the previous section linking elevated
zonulin with disease, only a fraction of the patients
with the condition showed elevated levels of
zonulin.
When Vojdani et al. measured IgG and IgA antibody levels against
zonulin at the same time points (zero, six, 24, and 30 hours), they found that serum
zonulin was somewhat correlated
with anti-
zonulin IgG and highly correlated
with anti-
zonulin IgA.
In celiac disease patients, 67 percent (20/30) produced antibodies to
zonulin, compared to just 10 who presented
with elevated
zonulin.
Make sure you're not drinking a whole bunch of water
with your meals and avoid all the inflammatory things that are gonna be driving that
zonulin stimulation.
I then came across the research of Dr. Alessio Fasano on
zonulin, a protein that is expressed in all autoimmune conditions and associated
with increased intestinal permeability.
