Good Gut Health Is Essential For Immunity
Jun 22nd 2009 · by Catherine Osthaus
Did you know that your gut is your body’s primary defense against pathogenic bacteria and viruses that create illnesses?
I have been reading Gut and Psychology Syndrome by Dr. Natasha Cambell-McBride and found the chapter on our Immune Systems so incredibly fascinating.
Here is a very brief summary of how our immune system is related to our gut flora:
- Bad intestinal flora weakens the immune system
- Antibodies (immunoglobulins) start to attack our own body tissues such as brain and nervous system
- The bifidobacteria (good gut bacteria) cell wall creates Muramil Dipeptide. These muramil dipeptide initiates the production of lymphocytes.
- Lymphocytes are what protect us from viruses and tumours. They are able to recognize and kill or neutralize any foreign invader virus/cells. Source
- People with damaged gut flora have a lesser amount of lymphocytes
- Lymphocytes create immunoglobulins including Secretory Immunoglobulin A (IgA).
- IgA is one of the most important as it is secreted in our bodily fluids and mucus membranes (eyes, nose, mouth, genitals).
- Bad bacteria, viruses and parasites enter our bodies through our mucus membranes.
- IgA is critical for good mucosal immunity.
- IgA breaks down quickly but the good bacteria in the gut are able to slow down this process.
There is a lot more wonderful information in this book. As well as methods and supplements on how to heal your gut flora. You can also find out more information at the GAPS diet website.
Lacto-fermented foods have traditionally been used for keeping our gut flora healthy. These foods include milk kefir, water kefir, kombucha, clobbered milk, yogurt, lacto-fermented fruits and vegetables. I have created videos on how you can make lacto-fermented sauerkraut and how to lacto-ferment fruit. All of these foods are loaded with beneficial flora for gut health.









I am on a low carb diet. I really like being able to eat (otherwise not allowed stuff) that has been lacto-fermented. I can eat cracked wheat or oatmeal that has been lacto-fermented overnight. Those in itself have more carbs than the 20 allowed. But I am still losing weight. The way I make the oatmeal or cracked wheat, is I take about 1/3 cup of the grains, enough non-chlorinated water to cover and about 1 cup of kefir milk. Put it in the oven with the light on, and in the morning it is soft and warm and ready to eat just as is (all bubbly)(I don’t cook it). I am leaving the cracked wheat in about 24 hours.
The other day I lacto-fermented grapefruit juice, after a few days, I decided to shake the jar. Not a good idea, it had carbonated up and spewed everywhere. But anyway I know it works. Tastes good also.
That is great that you can eat grain on your low carb diet. I have tried to eat fermented grains and unfortunately can’t tolerate very much of it. I feel it is important to listen to your body and if all is well then great! I have just been on the GAPS intro diet and eliminated dairy (including butter) and eggs for just a few days and was amazed at how well I felt. Unfortunately living on soup, meat and cooked non fibrous veg is very difficult so I was not on it for very long. It showed me that I can’t tolerate fermented dairy as I introduced yogurt. This is why I have been struggling for so long!
I lacto-ferment grains for my kids and husband and am going to attempt my 4th try on a sourdough starter.
