Cornmeal is a type of coarse flour made by grinding dried corn kernels, including the bran, endosperm, and germ of a corn seed. It is naturally gluten-free and safe to eat for those with celiac disease. Cornmeal is high in starch, with one cup (159 grams) containing 117 grams of starch, or 74% by weight. It is also a good source of protein, fiber, and nutrients such as selenium, magnesium, and potassium. When following a starch-based diet, cornmeal can be used in various ways, including as a coating for fried foods, as a thickener for sauces and stews, and as an ingredient in baked goods. However, it is important to note that cornmeal is different from cornstarch, which is a more refined product made from only the endosperm of the corn kernel. Cornstarch has a fine, white powder texture and is often used as a thickening agent or binding agent in baking. To maintain a healthy starch-based diet, it is recommended to choose whole grain cornmeal instead of de-germed varieties, as the latter loses some fiber and nutrients during processing.

What You'll Learn
Cornmeal is a gluten-free, whole-grain flour
As a whole-grain flour, cornmeal contains a rich blend of proteins, fats, carbohydrates, fibre, and other nutrients, including selenium, magnesium, and potassium. However, the nutritional content can vary between different types of cornmeal. For example, superfine cornmeal has fewer nutritional benefits compared to whole-grain versions, with more calories, carbohydrates, fat, and protein. On the other hand, refined cornmeal may have added nutrients, so the exact nutritional composition depends on the brand.
When choosing cornmeal, opt for whole-grain varieties instead of de-germed or refined options. De-germing and refining processes can strip cornmeal of its fibre and nutrients, and these types of cornmeal are associated with a higher risk of type 2 diabetes, heart disease, and weight gain due to their high starch and carbohydrate content. Whole-grain cornmeal, on the other hand, provides a good source of fibre and nutrients and can be a healthy addition to a starch-based diet.
Cornmeal is commonly used in dishes such as polenta, grits, cornbread, and porridge. It gives food a rustic, corn-forward flavour and texture. In baking, cornmeal can be used to dust baking sheets to prevent dough from sticking and to create a crisp, evenly spread crust for pizzas, flatbreads, and galettes. It is important to note that cornmeal and cornstarch are not interchangeable in recipes due to their distinct characteristics and intended uses.

Cornmeal is high in starch and carbs
Cornmeal is a type of coarse flour made by grinding dried corn kernels. It is naturally gluten-free, which means it is safe to eat for people with celiac disease. Cornmeal is also a good source of selenium, vitamin B6, folate, and fibre. It can be used to prepare polenta, cornbread, fritters, and more.
However, it is important to note that cornmeal is very high in starch and carbohydrates. A 61-gram serving of cornmeal contains 47 grams of carbohydrates, which come from its high starch content. One cup (159 grams) of cornmeal contains 126 grams of carbohydrates, of which 117 grams (74%) is starch. This makes cornmeal a high-starch food, along with other refined sources like some breakfast cereals and wheat flour.
A diet high in refined starches is linked to an increased risk of type 2 diabetes, heart disease, and weight gain. These highly refined starches can cause blood sugar to spike and then fall rapidly. Therefore, it is important to limit the intake of refined starches like cornmeal and opt for whole, unprocessed sources of starch such as sorghum flour, oats, and potatoes, which are great sources of fibre and nutrients.
When choosing cornmeal, it is recommended to select a whole grain variety instead of a de-germed one. Whole grain cornmeal retains more fibre and nutrients, whereas the de-germing process removes some of these beneficial components. Additionally, stoneground cornmeal is less processed than de-germinated cornmeal, resulting in a richer taste and higher nutrient content. However, some de-germinated corn meals are enriched with added vitamins and minerals.

Cornmeal is coarse and has a gritty texture
Cornmeal is a type of flour made by grinding dried corn kernels. It is gluten-free and contains a variety of nutrients, including proteins, fats, carbs, fibre, selenium, magnesium, and potassium. The bran, endosperm, and germ of the corn seed are all ground up to make cornmeal, resulting in a rough, yellow flour that retains the taste and texture of corn. The texture of cornmeal can range from coarse to fine, depending on the type of corn used and the method of grinding.
Cornmeal has a coarse and gritty texture, especially when stone-ground, which includes the fibrous exterior of the kernel. This results in a whole-grain flour with a rough and uneven appearance, including spots of yellow, gold, blue, red, or other colours, depending on the variety of corn. The coarser texture of cornmeal makes it suitable for dusting baking sheets to prevent dough from sticking. It helps create a crisp and evenly spread crust for pizzas, flatbreads, and galettes.
In contrast, cornstarch has a very fine, smooth, and powdery texture, almost like velvet. It is made from only the starchy endosperm of the corn kernel, with the bran and germ removed. This process removes the protein and fibre, resulting in a product that is mostly carbohydrates. Cornstarch is valued for its ability to make baked goods tender, light, and soft, and it is commonly used as a thickening agent in sauces, stews, and gravies.
While cornmeal and cornstarch have distinct characteristics, they both play important roles in cooking and baking. Cornmeal, with its coarse and gritty texture, contributes to the rustic, corn-forward flavour and texture in dishes like polenta, grits, and cornbread. On the other hand, cornstarch's fine texture and lack of flavour make it ideal for thickening sauces and creating delicate textures in baked goods without altering their taste.
When deciding whether to use cornmeal or cornstarch, it is essential to consider their unique properties and how they will impact the final dish. Cornmeal is a whole-grain flour that provides flavour, texture, and nutritional benefits, while cornstarch is a refined flour primarily used for its functional properties, such as thickening and softening, without contributing much flavour.

Cornmeal has a sweet, earthy flavour
Cornmeal is a type of coarse flour made by grinding dried corn kernels. It is naturally gluten-free and safe to eat for those with celiac disease. It is also a whole-grain flour, containing a rich blend of proteins, fats, carbs, fibre, and other nutrients such as selenium, magnesium, and potassium. Cornmeal has a gritty texture and a sweet, earthy flavour.
The bran, endosperm, and germ of a corn seed are all ground up to make cornmeal. The type of corn used determines the colour of the cornmeal, which can be yellow, white, light blue, bright golden, dull straw, or red. The texture can also vary, depending on the type of processing the corn kernels undergo. Stone-ground cornmeal, for example, includes the fibrous exterior of the kernel, resulting in a coarse texture. In contrast, cornmeal milled between metal rollers has a finer texture, as some manufacturers remove the bran before milling to improve shelf life.
Cornmeal is commonly used to make dishes like polenta, grits, and cornbread. It can also be used to dust baking sheets to prevent dough from sticking and to create a crisp, evenly spread crust for pizzas, flatbreads, and galettes. When choosing cornmeal, opt for a whole grain variety instead of a de-germed one, as the latter loses some fibre and nutrients during processing.
Cornmeal is a staple food that provides a rustic, corn-forward flavour and texture to dishes. Its sweet, earthy flavour can enhance the taste of baked goods and savoury dishes. When used in baking, cornmeal adds a gritty feel and a corn flavour that is distinct from the neutral taste of cornstarch, which is often used as a substitute for cornmeal in baked goods due to its finer texture. However, it is important to note that cornstarch and cornmeal have very different uses and traits, and substituting one for the other in recipes can lead to undesirable results.

Cornmeal is used in polenta, cornbread, and pizza
Cornmeal is a type of coarse flour made by grinding dried corn kernels. It is naturally gluten-free and a good source of starch. While cornmeal is commonly associated with cornbread, it is also used in polenta and pizza.
Polenta
Polenta is made by whisking cornmeal into boiling water and cooking it until it is soft or firm, depending on the desired texture. The longer you cook polenta, the more pronounced the sweet corn flavor becomes. It is important to note that the quality of the cornmeal used will impact the final result.
Cornbread
Cornbread is a type of quick bread that typically includes cornmeal as one of its main ingredients. While it is possible to make cornbread without cornmeal, as evidenced by the existence of "no cornmeal cornbread" recipes, cornmeal is generally considered integral to the dish.
Pizza
Cornmeal is sometimes used in pizza-making, although opinions vary on its effectiveness. Some people use cornmeal as a substitute for flour in pizza dough, while others use it to prevent the dough from sticking to the pan or peel. However, some pizza enthusiasts dislike the powdery residue that cornmeal can leave on the bottom of the crust.
