Managing Celiac Disease

Wheat is the grain on which Western civilization was built. It's been
used for thousands of years as the foundation of our diet. But 1 out
of 100 Americans has a condition called celiac disease, which is an
intolerance to wheat, barley and rye. Its symptoms can be subtle, but
if you don't stick to a gluten-free diet you could be damaging your
body and not even know it. More from Mayo Clinic.
