What is inside the fecal stream that is driving inflammation.

The fecal stream is behind the inflammation in crohn's disease. Rutgeerts et al. showed contact with intestinal fluids in patients caused disease within 8 days.(1) (2)

Harper confirmed this a third time (3). Small bowel effluent causes inflammation.

However, patients that received an enema of effluent that first went through a 22-nm ultrafiltrate showed no such response. Showing that fecal content larger than 0.22 micron is responsible for the inflammation. Either bacteria or large particles in the fecal stream cause the inflammation. (3)

Macrophages within the lamina propria show an immune response to E. coli, Streptococci and Listeria (4).

Serological markers like anti-OmpC can predict CD disease years before the diagnosis. (5)

I would think it is the fecal stream that feeds the existing bacteria responsible for the inflammation. In some instances I also would speculate that some foods have components that are similar to some secretions output by certain bacterium which increase inflammation. That is the hypothesis I came to regarding my adverse reaction to onions when I was ill. I can eat them without any consequences now.

It would be difficult to explain long term remission otherwise. Especially when not using a typical Crohn’s treatment.

Much of our food is both GMO and doused In glyphosate which adds another layer of complexity to it all.
