GMO vs Non-GMO Corn – What are the differences.

GMO CornIn the quest for cheaper food many farmers, have switched to Monsanto’s Roundup Ready corn seeds. What Monsanto did to the corn was modify its genetics so that the weed killer and herbicide, Roundup, won’t kill the corn. This enables the farmers to spray the corn crops with high amounts of roundup to kill the weeds so that they don’t have to hand till each row. So a huge labor savings resulting in lower production costs, and cheaper food.  Concept is great, because we all want lower cost foods.

The problem is though that that Roundup weed killer, and its active ingredient glyphosate, is absorbed by the corn plant through the plant and the soil and is incorporated into the plant. Without the genetic modification the corn would be quickly killed, but it lives on.  All that glyphosate ends up in the corn we eat and all the foods derived from corn like corn syrup, HFCS, beef, milk, eggs, and hundreds of other food products.

What has also been found is that, as can be expected, there are high levels of glyphosate in the corn, more than 18 times than what is allowed in the US water supply and 65 times more than what is allowed in Europe. Worse yet is the glyphosate level in corn is 130 times higher than what has been shown to cause organ damage.  So what are you putting on your families table?

Not only are the levels of glyphosate extremely high, but also very high levels of formaldehyde and surprisingly the levels of many minerals are much lower in the GMO corn vs conventionally grown.

Below is a table listing the differences in toxins and minerals from two adjacent midwest US fields, one genetically modified corn and the other non-GM

Parts per million (ppm)
Ingredient GM corn Non-GM corn

Glyphosate 13 0
Formaldehyde 200 0
Nitrogen 7 46
Phosphorus 3 44
Potassium 7 113
Calcium 14 6130
Magnesium 2 113
Sulphur 3 42
Manganese 2 14
Iron 2 14
Zinc 2.3 14.3
Copper 2.6 16
Molybdenum 0.2 1.5
Boron 0.2 1.5
Selenium 0.6 0.3
Cobalt 0.2 1.5

Even though the GM crops weren’t sprayed with formaldehyde as the  glyphosate breaks down one of the by-products is formaldehyde.  You don’t want formaldehyde in your body until you’re laid to rest.

The easiest way to make sure you aren’t poisoning your family with GM corn is to buy only organic corn or grow the corn yourself.  But you’ll still get glyphosate and formaldehyde onto your dinner table. Corn and Soy (which is also genetically modified and sprayed with Roundup) are the primary grains fed to cattle, pigs, chickens, and farm raised salmon, shrimp, catfish and others.  So if a cow is fed an diet rich in GM corn and soy, then the toxins will be in the meat and the milk. For chickens it will also be in the eggs.  If you buy organic meats, milk, and eggs, then they must be fed non-GM foods so those are the sure bet for your families safety.

There are many genetically modified foods besides corn:

  • Soybeans – Most is GM
  • Corn – Most is GM
  • Wheat – non is allowed in the US yet but it is found in Europe for non-foods and for animal feed.
  • Rapeseed and Canola oil
  • Sugar Beet
  • Potato – These have been modified to increase the amount of starch.
  • Cotton – This not only is used for clothing, but also for animal feed.
  • Paypaya – Modified to be more disease resistance.
  • Apples – Apples may soon show up in the GM column. Not for herbicide resistance but to keep them from browning.

Some plans have been genetically modified to product their own toxins that will kill insects that eat the plant. This does save spraying the crops with insecticides, but they make their own which can’t be good for us.

Yes, organic foods are more expensive, but go to Home Depot and take a look at a bottle of Roundup and read the cautions. Just picture spraying that on your food as you cook it or mixing into the kids cereal in the morning.  Read the label, you’ll shop organic.
