permeability, bacteria and their toxins,
undigested food, and waste may leak out of
the intestines into the bloodstream.
Remember that 70 percent to 80 percent of
your body’s immune system is stationed in
your gut.
So when this garrison of immune cells
encounter stuff inside the body that doesn’t
belong there, they react. Strongly.
Now, maybe that “foreign invader” is just
a piece of incompletely digested chicken
protein, allowed to “leak” inside the body
accidentally. A leaky gut forces the immune
system to attack things that could be totally
harmless (like a useful source of protein) if
they had stayed where they belonged. But
since they didn’t, your immune system now
identifies that chicken protein as foreign and
attacks it.
This is one theory on how food allergies
are born.
