"Corn," in the Bible, does not refer to maize. It refers to barley, wheat, etc. This alone does not mean that maize is harmful in any way, but it should raise a red flag. Maize can be tasty, and it will sustain life to a large degree. But this does not mean it is the best choice for our money in regard to health and strength (Isaiah 55:2).
We all have a picture in our heads of American Indians showing Pilgrims how to plant and raise Indian corn. The Pilgrims rightly praised God for the kind natives that had much wisdom to teach about plants in the new world. However, this does not mean that all of their food choices were Biblical or even nutritious in the long run. Many American Indians ate horses, dogs, reptiles, etc. (all unclean in the Bible). The Aztecs and some American Indians (e.g., Anasazi, Mohawk) were even cannibals! Much of their helpful knowledge about plants was tainted with superstitious animism.
The first problem with corn is that it (like cassava, etc.,), contains anti-thyroidal substances. The thyroid produces hormones that are involved in metabolism, male testosterone, fertility, digestion, muscle control, cognitive function, mood, heart and bone health, etc. Any loss of strength, energy or function in these things is certainly not ideal. Many people that are experiencing problems in these areas are unaware of the degree that their daily diet choices are to blame.
Notice the anti-thyrodial effects of corn:
"Effect of maize (Zea mays) on thyroid status under conditions of varying iodine intake in rats…Presence of cyanogenic glucosides, which are antithyroidal substances, in maize is well established…Edible part of maize contains thiocyanate (20 ± 2mg/kg), cyanogenic glucosides (10.12 ± 1.2 mg/kg) and glucosinolates (2.5 ± 0.2 mg/kg)...Significant increase in urinary excretion of thiocyanate and iodine was observed in the rats fed maize for 45 days and 90 days, respectively, associated with increased thyroid weight, decreased TPO activity and serum total circulating T4 and T3 levels as compared to their respective controls. A relative state of morphological as well as biochemical hypothyroidism developed gradually in chronic maize fed rats…Adequate iodine supplementation in maize fed groups of rats improved the thyroid status to a certain extent but failed to prevent the antithyroidal activity of the plant food…In maize-fed rats the thyroid peroxidase activity decreased significantly compared to the corresponding controls…Supplementation of iodine to both the maize-fed groups resulted in increase of the TPO activity in comparison to only maize-fed groups but failed to restore its activity to normal…The overall results showed that chronic consumption…of maize gradually developed a relative state of biochemical as well as morphological hypothyroidism even in presence of adequate iodine in circulation…Prolonged feeding showed more deleterious effect on thyroid status even in presence of adequate iodine intake."

One of the antithyroidal substances in corn is thiocyanate. It blocks the thyroid from absorbing iodine. It is found in cigarette smoke, as well as corn:
"Thiocyanate has been considered as a possible cause of thyroid disorders because it inhibits iodide transport…Thiocyanate or thiocyanate like compounds primarily inhibit iodide concentrating mechanism of the thyroid…At low doses, thiocyanate was shown to inhibit the uptake of iodide; in addition it also affects the organic binding there…The latter effect of thiocyanate cannot be counteracted by excess iodide…Feeding of cyanogenic foods viz...maize (Zea mays Linn)...decreased the serum total T3 and T4 levels significantly…studies in Zaire have shown that cassava a staple diet in the region has definite antithyroid action in man and animals, resulting in the development of endemic goiter and cretinism…In spite of adequate iodine nutritional status, endemic goiter is prevalent in many regions because the urinary iodine does not always truly reflect the iodine nutritional status in an environment where consumption of food containing thiocyanate precursors is relatively high…"
(Biochem Pharmacol (Los Angel) 4:171.)
Corn chips are also often made with oils such as sunflower, canola, etc., that can inhibit the thyroid.
Pesticides are the second problem with corn:
"'I have brought wheat crackers, granola cereal and corn meal from home and there's a fair amount in all of them,' FDA chemist Richard Thompson wrote to colleagues in an email last year regarding glyphosate...Separately, FDA chemist Narong Chamkasem found 'over-the-tolerance' levels of glyphosate in corn..."

"Glyphosate is the active ingredient in herbicides such as Roundup. In the US, glyphosate is used in the commercial production of crops genetically modified to survive being sprayed with the herbicide – currently that's 94% of soybeans and 89% of corn…Worries about the health risks of glyphosate-based herbicides are not confined to cancer. An important study from Michael Antoniou at King's College in London shows that following long-term (2-year) exposure to an ultra-low dose of Roundup resulted in non-alcoholic fatty liver disease (NAFLD) in rats...NAFLD is a progressive disease resulting in the toxic accumulation of fat in the liver…The glyphosate equivalent amount of Roundup ingested by the rats on a daily basis in this study was 437,500 times lower than what is permitted in the US. This amount of Roundup was at least 100-fold below what the individuals in Mills's study are estimated to have consumed on a daily basis to give the amount of glyphosate seen in their urine…NAFLD can lead to liver cirrhosis and cancer. NAFLD is much more common in young people than in past decades, and liver cancer among Americans has increased over three-fold since 2000… Glyphosate is now found in most, if not all, food products, including baby foods…"

"Glyphosate, the active ingredient in Roundup®, is the most popular herbicide used worldwide... Residues are found in the main foods of the Western diet...glyphosate enhances the damaging effects of other food borne chemical residues and environmental toxins...Consequences are most of the diseases and conditions associated with a Western diet, which include gastrointestinal disorders, obesity, diabetes, heart disease, depression, autism, infertility, cancer and Alzheimer's disease...We have found clear evidence that glyphosate disrupts gut bacteria...The rats that were chronically exposed to Roundup® developed several pathologies over the course of their lifespan, including large mammary tumors in the females and gastrointestinal, liver and kidney pathologies, especially in the males. The males developed both skin and liver carcinomas...Tryptophan is an essential amino acid... Serum tryptophan depletion [by glysophate] leads to serotonin and melatonin depletion in the brain...Since serotonin (derived from tryptophan) is a potent appetite suppressant...it follows that serotonin deficiency would lead to overeating and obesity...[and] can lead to an extreme inflammatory bowel disease that would severely impair the ability to absorb nutrients through the gut, due to inflammation, bleeding and diarrhea...Zinc deficiency is a major problem worldwide...Phytates, found in many nuts and grains, bind to dietary minerals and interfere with their absorption. Lactobacilli and other beneficial gut bacteria produce the enzyme phytase, which catalyses the release of phosphate from phytates and improves the intestinal absorption of important minerals such as iron and zinc...Because glyphosate reduces the number of these types of bacteria in the gut, it should enhance the chelating potential of phytates...zinc deficiency in the brain would be expected to lead to the build-up of amyloid-β, a key factor in the development of Alzheimer's disease. Zinc deficiency has also been implicated in autism...and ADHD...An increased incidence of inflammatory bowel disease has been found in association with multiple sclerosis...Cholesterol sulfate plays an essential role in fertilization...and zinc is essential to the male reproductive system...Thus, the likely reduction in the bioavailability of these two nutrients due to effects of glyphosate could be contributory to infertility problems...Roundup was shown to disrupt StAR expression, thus interfering with testosterone synthesis...It was shown that Roundup® interferes with testosterone synthesis even at very low environmental doses...Another type of cancer that may be implicated with glyphosate exposure is breast cancer...Over the last decade, there has been widespread adoption in the U.S. of Roundup Ready® (RR) crops, particularly for the major productions of soy, beet sugar, and corn that supply the processed food industry. The recent alarming rise in type-2 diabetes has been attributed to excess intake of high fructose corn syrup, which has increased to unprecedented levels in the last decade...This refined sugar is now usually derived from glyphosate-exposed GM corn..."

Eating organic will greatly help! However, in regard to corn, even organic crops can become contaminated with glyphosate:
"Herbicide drift from neighboring fields can land on any crop labelled as organic. While the amounts will be considerably lower than conventional crops, it is still something to be aware of. Non-GMO crops can also become contaminated by cross-pollination with GMO crops."
The third problem with corn is the phytic acid content. Corn is very high in phytic acid compared to other grains:
"…phytic acid reduces mineral absorption during the meal but doesn't have any effect on subsequent meals…snacking on nuts between meals could reduce the amount of iron, zinc and calcium you absorb from these nuts but not from the meal you eat a few hours later…Phytic acid impairs the absorption of iron, zinc and calcium…"
Note: It may be possible to prepare corn properly, and remove many of the anti-nutrients (if non-GMO and chemical-free corn can truly be found in these last days when mankind destroys the earth - see Rev. 11). For example, fermentation helps deactivate anti-thyroid cyanogenic glucosides. The fast paced, fast food American lifestyle has lost the wisdom of how to prepare meals. And with so many women working outside the home, many cannot find the time to prepare food properly - soaking, fermenting, cooking, etc. The end result is lowered thyroid hormone levels, and all the weakness and impairment of bodily systems that this brings.
Corn is often eaten with most modern meals, in some manner, and rarely is it sprouted or fermented. Corn is found in almost every food product to some degree.
[If one chooses to eat corn, eating organic, sprouted, etc., and with lots of garlic and onions will help minimize the above problems to some degree.]
