Although as a general point, the moment you read something is "fortified

translates as naff all natural nutritional value is left in this product!

Although corn (maize) has its own peculiarity regarding availability
(rather than content):

"The traditional food preparation method of corn (maize),
nixtamalization, by native New World cultivators who had domesticated
corn required treatment of the grain with lime, an alkali. It has now
been shown that the lime treatment makes niacin nutritionally available
and reduces the chance of developing pellagra. When corn cultivation was
adopted worldwide, this preparation method was not accepted because the
benefit was not understood. The original cultivators, often heavily
dependent on corn, did not suffer from pellagra. Pellagra became common
only when corn became a staple that was eaten without the traditional
treatment."

So not just for walls...
