No. The alkali just allows the hulls to be easily separated from the kernels and removed. This makes the kernels more tender, easier to digest and/or process. I'm the same guy who can't digest oats and I also can't digest corn hulls. I can eat corn flakes and cornbread and other processed corn, but if I eat whole corn or corn on the cob, it just passes right through me whole, a rather uncomfortable and totally pointless experience. So hominy is perfect for people like me and my wife makes some wonderful Mexican dishes with hominy. (Like chiles rellenos set into a hominy casserole.) But apparently the increased tenderness has made it popular with everybody.
