In fact, much of it was never intended to be eaten directly by humans at all.
So what exactly is growing in those vast fields?
The answer reveals a fascinating side of modern agriculture that many people never realize exists.
The Corn You See Everywhere Is Usually Field Corn
The overwhelming majority of corn grown across the United States is known as field corn, sometimes called dent corn or feed corn.
Unlike sweet corn, field corn is not harvested for fresh eating.
Instead, it’s grown for its high starch content and remarkable versatility.
By the time field corn is harvested, its kernels have become hard, dry, and dense.
If you tried eating it straight from the cob, you would quickly notice the difference.
It’s tough, starchy, and far less sweet than the corn served at cookouts and family dinners.
What Is Field Corn Used For?
Although most people don’t eat field corn directly, they encounter it every day in countless products.
Field corn is commonly used for:
Livestock feed
Cornmeal
Corn flour
Cornstarch
Breakfast cereals
Corn oil
Ethanol fuel
Industrial food ingredients
Sweeteners such as corn syrup
Because it serves so many purposes, field corn has become one of the most important agricultural crops in North America.
