Your gut and your immune system
You might be surprised to find out that there’s a deep-running connection between your immune system and your digestive system.
Turns out, three-quarters of your immune system resides in your digestive tract. And that entire immune system is protected from its external environment (your food) by a thin, fragile lining that’s only one cell thick. If that lining is damaged and the barrier that it creates is penetrated, crazy things happen. You become allergic to foods you could normally handle without a problem, you get sick much more easily, and your whole immune system becomes overactive, which can result in chronic inflammation.
And the things that punch holes in your digestive tract are things that you put there yourself – food.
