Something I never understood about Pesach dietary laws

[figmo]

The whole point of the dietary change during Passover, as I understood it, was to eliminate leavening (yeast) from the diet because they didn't have it when going through the desert.

Why, then, do we eliminate whole grains, which have nothing direct to do with the leavening? Why is it okay to make matzoh with whole grains, but only okay to eat foods made with crushed matzoh as a "grain" instead of the same types of grains used to make the matzoh?

This never made sense to me, and nobody has ever explained it.

And now I find myself irrestiably reminded of Avram Grumer's "Banned from Egypt"...

"We left in such a hurry that the bread we baked was flat;
Descendants will eat matzo to remind themselves of that.
Now we can't help but wonder how things would have been, perchance,
If we had been so hurried as to not put on our pants."
