Grits are made from dried, ground corn, specifically from a type called dent corn. The corn is treated with an alkali solution in a process called nixtamalization, which removes the tough outer hull and makes the grain more nutritious. After this treatment, the corn is dried and ground into the coarse meal that becomes grits.
What Are Grits Made From Exactly?
Grits come from corn. But not the sweet corn you eat on the cob in summer. They come from dent corn, also called field corn. This corn has a higher starch content and a tougher texture. It is the same corn used for animal feed and corn syrup, but the version for grits goes through extra steps.
The key step is nixtamalization. The corn is soaked and cooked in an alkaline solution, usually limewater. This loosens the hard outer hull, which is then washed off. The process also changes the corn’s chemistry. It makes the nutrient niacin more available for your body to absorb. Without this step, the corn’s niacin stays bound up and passes through you.
After the hull is removed, the corn is dried and ground. The coarseness of the grind determines the type of grits. Stone-ground grits are the coarsest and take the longest to cook. Quick grits are ground finer and cook in about five minutes. Instant grits are precooked and dehydrated.
What Is the Nutritional Difference Between Stone-Ground and Instant Grits?
Stone-ground grits are the whole grain. They contain the germ and the bran, which hold most of the fiber, vitamins, and minerals. Instant grits have the germ and bran removed for a longer shelf life and faster cooking. This strips away most of the fiber and many of the nutrients.
Here is a comparison of one cup of cooked grits without added fat or salt. Values are approximate and vary by brand.
| Type | Calories | Fiber | Iron | B Vitamins |
|---|---|---|---|---|
| Stone-ground | 150 | 3-4 g | Higher | Present |
| Quick | 140 | 1-2 g | Moderate | Some added |
| Instant | 130 | Less than 1 g | Low | Often fortified |
Instant grits are often “enriched” which means synthetic vitamins are added back. But the fiber cannot be replaced. If you want the most nutrition from your grits, stone-ground is the better choice.
Is There a Difference Between Grits and Polenta?
Both are ground corn. The main difference is the type of corn and the grind size. Grits are made from dent corn and are usually ground finer. Polenta is made from flint corn, which is harder, and is ground more coarsely.
In practice, you can use them interchangeably in most recipes. But the texture will be different. Grits turn out creamier. Polenta stays more grainy and holds its shape better when cooled. The cooking method also differs. Grits are stirred often to prevent lumps. Polenta can be stirred less and sets up firm enough to slice.
Regional tradition matters too. In the American South, grits are a breakfast staple. In Italy, polenta is a side dish or base for stews. Neither is healthier than the other. Both are cornmeal with the same basic nutrition.
Are Grits Gluten-Free?
Yes, grits are naturally gluten-free. Corn does not contain gluten. But cross-contamination is a real concern. Some processing facilities also handle wheat, barley, or rye. If you have celiac disease or a strong gluten sensitivity, you need to check the label.
Look for a “certified gluten-free” label on the package. This means the product was tested and contains less than 20 parts per million of gluten. Stone-ground grits from a smaller mill are more likely to be processed in a dedicated gluten-free facility. Large brands that also mill wheat are riskier.
How Are Grits Traditionally Served?
In the Southern United States, grits are most often served as a breakfast dish. They are cooked with water or milk and stirred until thick and creamy. Butter, salt, and black pepper are the classic additions. Some people add shredded cheese for cheese grits, or mix in cooked shrimp for shrimp and grits.
Grits can also be served savory with eggs, bacon, or sausage. Some people eat them sweet with sugar, honey, or maple syrup. The texture is similar to porridge. Leftover grits can be poured into a pan, cooled until firm, then sliced and pan-fried. This is called fried grits or grits cakes.
Outside the South, grits are less common but still available. They are sometimes labeled as “corn grits” in grocery stores. The cooking method is the same regardless of where you buy them.
Can Grits Be Part of a Healthy Diet?
Yes, but it depends on how you prepare them. Plain grits are a source of carbohydrates with some iron and B vitamins. Stone-ground grits provide more fiber, which helps with digestion and blood sugar control. Instant grits are mostly starch with little fiber.
The problem comes from what people add. Butter, cheese, cream, bacon, and sausage turn a simple grain into a high-calorie, high-fat meal. A bowl of cheese grits with bacon can easily have 500 to 700 calories and 30 grams of saturated fat. That is fine as an occasional meal but not daily.
If you want a healthier version, use water or low-fat milk instead of cream. Add vegetables like spinach or tomatoes. Use a small amount of sharp cheese for flavor instead of a lot of mild cheese. Skip the bacon and sausage. A bowl of grits with a poached egg and hot sauce is filling and balanced.
What Is the Best Way to Cook Grits?
The method depends on the type of grits. For stone-ground grits, you need patience. Bring four cups of water or milk to a boil. Add one cup of grits slowly while whisking to prevent lumps. Reduce the heat to low and cook for 30 to 45 minutes, stirring every few minutes. Add more liquid if it gets too thick. Season with salt at the end.
For quick grits, the ratio is the same but the cooking time is about five minutes. Stir constantly to avoid lumps. Instant grits just need boiling water and a minute of stirring. No cooking required.
Here are a few tips that make a real difference. Toast the dry grits in a pan for two minutes before adding liquid. This adds a nutty flavor. Use broth instead of water for savory grits. Add a pat of butter or a splash of cream at the very end for richness. Never add cheese until the grits are fully cooked and off the heat. Cheese added too early makes the grits gluey.
Frequently Asked Questions
Are grits the same as cornmeal?
No, grits are coarser than cornmeal. Cornmeal is ground finer and is used for baking and breading. Grits are ground more coarsely and are cooked as a porridge.
Do grits need to be rinsed before cooking?
No, you do not need to rinse grits. Rinsing can wash away some of the starch and make the final dish less creamy. Just add them directly to the liquid.
Can you eat grits raw?
No, raw grits are too hard to digest and taste unpleasant. They must be cooked in liquid until soft and creamy. Eating them raw can cause stomach discomfort.
Are grits a vegetable or a grain?
Grits are a grain. Corn is technically a grain, not a vegetable. Even though corn is often treated as a vegetable in cooking, it is a cereal grain botanically.
