There was a recent article published in Cell, Host and Microbe where researchers took samples of intestinal flora in various parts of the digestive tract in many people with Crohn’s Disease and discovered that there are more “bad” bacteria and less “beneficial” bacteria in the intestinal tracts of those people. They also stated that the use of antibiotics tends to create this problem and make it worse.
That is EXACTLY what the problem is with a lot of these autoimmune diseases. Intestinal dysbiosis caused by overuse of antibiotics and exacerbated by poor Western diets. Leads to inflammation, leaky gut, and possible autoimmune diseases. There is no “may” to it. It DOES play a role in Crohn’s disease and many others.
This is also why autoimmune diseases can be reversed! Heal the gut – heal the disease. Which is what I did over three years ago.
I will post a link to the NPR article that discussed this research study, and I will also post the medical research paper on my media page so you can read it if you would like.
