The Dominance of Corn: Most Produced, Most Versatile
Corn, also known as maize, holds the undisputed title as the most produced grain in the United States. This dominance is driven by its incredible versatility, though its primary uses might surprise many.
- Animal Feed: The majority of corn grown in the U.S.—over half—is used as a high-energy food source for livestock, including cattle, pigs, and poultry. This underpins the massive American meat and dairy industries.
- Biofuels: A substantial portion of the U.S. corn crop is converted into ethanol, a biofuel used to power millions of vehicles. This renewable energy demand has been a key driver of corn production increases.
- Sweeteners: Corn is processed into high-fructose corn syrup, a common sweetener found in thousands of processed foods and beverages.
- Other Industrial Uses: The grain is also used to create a vast array of other industrial products, including starches, adhesives, and bioplastics.
This broad range of uses, from powering cars to fattening livestock, is why corn production statistics dwarf those of other grains in the U.S. Iowa and Illinois consistently lead the nation in production, benefiting from the rich soil of the 'Corn Belt'.
Wheat's Role in the American Diet: The Most Consumed for Food
When considering grains that form the core of the human diet in America, wheat is the clear winner. While its production volume is much lower than corn, its role in food products is far more direct and pervasive.
- Flour-Based Products: Wheat is the key ingredient in staples like bread, pasta, cereals, and baked goods. Its gluten content allows for the elasticity and structure necessary for these foods.
- Dietary Preferences: Consumer preferences drive wheat consumption, influenced by taste, texture, and familiarity with its countless applications in American cuisine.
- Historical Significance: As one of the world's oldest cultivated crops, wheat has a long history in human civilization and remains a foundation of many diets globally.
The American Grain Landscape: A Comparison
To highlight the key differences, the following table compares corn and wheat in the U.S. context.
| Feature | Corn (Maize) | Wheat |
|---|---|---|
| Production Volume | Highest in the U.S. (Billions of bushels) | Third among field crops in the U.S. |
| Primary Use | Animal feed, ethanol production, sweeteners | Direct human food consumption (bread, pasta) |
| Dominant Region | "Corn Belt" (e.g., Iowa, Illinois) | Midwest and Plains (e.g., Kansas, North Dakota) |
| Harvested Acreage | Highest acreage harvested | Significant but less than corn |
| Main Products | High-fructose corn syrup, ethanol, corn oil | Flour, bread, pasta, cereal |
How Corn and Wheat Are Used
Products from Corn
- Ethanol: Biofuel additive derived from corn starch fermentation.
- High-Fructose Corn Syrup: A liquid sweetener used extensively in beverages and processed foods.
- Cornmeal and Grits: Milled corn used in dishes like cornbread and polenta.
- Corn Oil: Cooking oil extracted from corn kernels.
- Livestock Feed: The largest end-use, providing energy for farm animals.
Products from Wheat
- Bread and Baked Goods: The primary ingredient for a wide variety of breads, pastries, and cakes.
- Pasta: Semolina, a type of wheat flour, is the basis for most pastas.
- Breakfast Cereals: Many common cereals are made from processed wheat.
- Couscous: A traditional North African and Middle Eastern dish made from semolina wheat.
- Bulgur: A cracked wheat product, often used in salads and pilafs.
Other Important Grains in the US
While corn and wheat dominate, other grains play important roles in the American food system. Rice is a significant crop, with production centered in Arkansas, and consumption has seen stable growth. Barley is used for both animal feed and for malt in the craft beer industry. Oats are a popular whole grain, especially for breakfast foods and in the growing alternative milk market. Sorghum is a drought-tolerant crop used for animal feed and biofuels, particularly in drier regions.
Conclusion: Context is Key
To answer the question, "What is the most common grain in America?", context is essential. Corn is the most common and widely produced by a large margin, but its use is primarily industrial. For direct human consumption, wheat holds the title as the most common and integral grain in the American diet. This dual reality highlights the complex nature of American agriculture and food consumption habits.

The distinction between production for industrial uses versus consumption for food demonstrates how different metrics can lead to different answers about the 'most common' grain.
