Today, in Part 3 of this short series on gut health, you can learn more about what all those billions of microbes and bacteria are doing down there in your gut, when things are going well…and when they are not!
About 70% of our immune cells are housed in the lining of our gastrointestinal system, or gut. Our gut is the biggest immune organ of the body. Likewise, it’s also where the majority of our microorganisms reside. This is not a coincidence. It makes complete sense. The food we eat is the largest exposure of foreign material that we bring into our body, so it makes sense for our immune system to reside in our gut. The outside world is literally experienced through the filter of the gut microbiome (and of course through our lungs), defending us against unwanted microbes and toxins.
