Ingredients Based On Corn

Corn is one of the most highly genetically modified (GM) ingredients in the United States.  Because of the challenges that genetic modification presents for our health and for the environment, I encourage people to eat organic corn. This also helps to avoid the high levels of pesticides and glyphosate used in growing the crop. The ability to use these chemicals are the primary reason for the genetic modification in the first place.  

Varieties of corn

There are many different forms of corn. When eating fresh, frozen or canned, it is sweet corn which only represents approximately 1% of all the corn we grow in the United States.  Field corn, sometimes referred to as dent corn, is the most common variety grown in the U.S. It represents nearly 60% of the entire corn crop. This variety is used for ethanol and livestock feed.   

Other uses for corn include corn flour, corn starch, corn syrup and in the confectionary business.  Popcorn is a separate variety. According to the Popcorn Board, the average American eats 42 quarts per year for a total consumption of 13 billion quarts.

Corn is also used in the textile industry and as a biodegradable plastic.

On the label

 Corn by itself is easy to identify in foods or on the label. The challenge is that it can be turned into a rather startling variety of ingredients. These ingredients make an appearance in nearly every single food category at the grocery store. This is problematic for the nearly 10 million people in the U.S. diagnosed with an allergy to corn. 

For those trying to avoid it, whether due to allergies or a desire to avoid GM contamination, it’s not always easy to know which ingredients got their start from corn.  If you’re looking to avoid GM products the easiest way is to choose either organic or GMO Project Verified products.  In the case of a food sensitivity or allergy use this list as a resource to help you know which products to avoid.
