Corn (aka Maize, and including Teosinte)

Corn is a high glycemic carb, even as an organic
heirloom (ancestral teosinte is over 50% carb by weight).
But that's far from the only problem with it.
Using Wheat Belly targets, a mere 6 corn chips,
one tortilla, is your entire meal/6-hour-interval
allotment of net carbs (15 grams).
Betcha can't eat just 6.
Dr. Davis posted expanded remarks on corn at:
Bashing: It's easy”.
The zein protein of corn is an analog
of the gliadin protein of wheat, and can trigger many of the same
The fat in corn is from the oil, which is about
50% Omega 6 linoleic acid in whole corn.
The ω6:ω3 ratio is about 32:1 in whole corn.
These numbers are much more adverse for refined corn oil.
Plus, the pittance of ω3 is ALA, and not the
desired DHA and EPA. If the subject at hand is corn chips,
expect even more industrial seed oils to be present unless
there's a Nutrition Facts panel handy that says something else.
Two landmark 1960s trials (SDHS, MCE)
used to support the
“cholesterol hypothesis”, where saturated fat
was replaced by corn oil, were
lately discovered to have misrepresented their
own data. Lowering cholesterol by increasing
corn oil intake actually increased the risk of death.
This is an issue for corn flours, and as of 2016,
now including corn masa flour. The folic acid form
of Vitamin B9 is being added to these flours as
fortification. This is a non-optimal, if not frankly
adverse, form of folate for a significant fraction
of the population. This is a matter of methylation
status due to epigenetics. If you are an MTHFR mutant,
this is yet another reason to avoid corn-based products.
the misleading grain industry definition of
explicit gene insertion)
Any corn which fails to include a credible claim
of “non-GMO” is almost certain to be GMO.
A claim of “organic” won't necessarily
assure that (except at Whole Foods, in 2018, maybe).
My posture on GMO is here.
GMO corn could be herbicide-resistant,
insecticide-expressing, or both.
Such food safety testing as has been done on these
traits has compared it to “regular” food,
and presumably subjects on a typical western diet,
complete with high noise from other adverse agents.
Until we have results from wheat-free low-carb high-fat
populations with known healthy gut flora, we won't
have any real idea what the risks actually are.
I'm not volunteering for the trials.
Glyphosate-resistant (Roundup-Ready®) corn is
likely to have some glyphosate uptake. Applying
it to the pre-emergent or growing plant is the
whole point of it. At least one researcher has
argued that the tight correlation between the
rise of glyphosate use and ASD is more than a
Bt corn will have Bacillus thuringiensis throughout.
Does this screw up gut flora? Again, until we have
adequately controlled studies on otherwise grain-free
LCHF subjects with
known healthy starting gut microbiomes, we won't know.
Such a test is impossible to run at present, because
we may be a couple of decades from knowing what an
optimal human microbiome is.
Bt corn, by the way, is rapidly becoming worthless
as a pest management technique, because it has
quite predictably given rise to Bt-resistant bugs
by western corn rootworm to multiple Bacillus
thuringiensis toxins in transgenic maize).
When the dosage is too low to kill all the bugs,
it gives reproductive advantage to the survivors,
who become the emergent majority. So what will
Big Ag™ do about this? Up the dosage?
Glufosinate-resistant corn (Liberty Link) may have
uptake of this herbicide. I haven't yet looked into
the potential hazards of that.
How about non-GMO?
Is it really?
(Clearfield) was created by chemo-mutagenesis
(aka: recklessly random gene insertion). The
industry passes it off as “non GMO”,
so being in Europe may not protect you on this.
Your bag of non-GMO chips will have a mystery
genome, which might have inherent risks, and
may have uptake of the herbicide imidazoline.
I haven't yet looked into the potential hazards
of imidazoline either, and given the known issues
with corn, why bother.
And that assumes everyone is being honest and
competent. When they aren't we get things like the
Starlink corn recall.
Thought that was history? “In August of 2013,
StarLink corn was reported to be found again
contaminating some foods in Saudi Arabia.”
On the whole, corn is worth avoiding entirely
in any form from any vintage. Like wheat
(“non GMO”, so far),
it takes some effort to avoid it, because being
yet another pervasive high-yield low-cost
commodity with inadequate risks disclosure,
corn is an all-too-common contaminant
(ingredient) in processed foods.
