One of the main reason I don’t eat fruit or vegetables of any kind is because some those non-soluble plant fibers can be like tiny razors cutting and damaging the cells that line the gut causing them to become inflamed and loosening the “tight junctions” between them. This allows foreign proteins in the gut to present themselves directly to our immune systems leading to antibody formation and subsequent allergy problems. In some instances these plant proteins are so similar to human proteins that the antibodies we produce to them can attack our own cells. This is what causes Type 1 diabetes, Lupus, Rheumatoid Arthritis, Hashimoto’s Thyroiditis, Crohn’s disease and thousands of other autoimmune diseases. Here’s a nice article that talks about how fiber damages our intestines. Here’s a link to a scientific description of the “leaky Gut Syndome”. The zonulins found in many vegetables especially wheat also cause the tight junctions in our gut that normally protect our immune systems against this exposure to foreign plant antigens to loosen, triggering exposure and the potential for many autoimmune diseases. Here’s a scholarly link about that.
Once you have antibodies against a plant protein whether it produces common allergies or an autoimmune condition every time you damage your gut with plant fiber or zonulins, you risk re-exposure to the plant protein that caused the initial antibodies to form. You have “memory” white blood cells for every antibody against which you are able to produce antibodies, including the bad ones that attack your own body. When the memory cells are re-exposed to the antigen in the inflamed gut that they are watching for, they cause the antibody producing cells to go into high gear producing antibodies against that protein. If it’s an allergy, you get allergy symptoms. If it’s an autoimmune disease, you get a flair of your condition for example an outbreak of a scaling rash in psoriasis.
Remember “Corn Oil Margarine”? I can still remember opening the shiny green paper boxes with the big ear of corn on it and getting the sticks out. Well here’s a quote from this article. (The article says “maize oil” this is the European term for “corn oil” which is high in Linoleic Omega-6 fatty acids): “On the other hand, excessive intake of linoleic acid may aggravate type 2 autoimmune disorders.” Type 2 disorders that are known include Grave’s disease, goodpasture’s Syndrome, Autoimmune Hemolytic Anemia, and Pemplagus, and If you look at the table of autoimmune diseases in the Wikipedia and look in the column labeled “Hypersensitivity” those with a Roman Numeral II are type 2 diseases. You will also see that for most autoimmune diseases the type class of hypersensitivity reaction hasn’t been determined yet. Much research to be done. The article also admits that Type I immunity is suppressed in the first line.
Too much fiber is also associated an increased risk of diverticulosis. . This is a painful condition where the strain of moving all that fiber through the gut causes weakening of the wall of the large intestines and eveually bubble like outpouchings to appear where food can get trapped an life threatening infections call diverticulitis can occur. This sometimes requires emergency surgery.
Leaky Gut and diverticulosis are a couple of the many reasons I do not include plants in my diet.
