Why it scores 78

Cornmeal achieves a strong FoodScore of 78/100, reflecting its significant nutritional contributions. A major bonus comes from its high fiber content, with 6.7g per 100g, which is a substantial amount for a grain and earns +8 points. It also receives a significant +12 points for its rich micronutrient profile, particularly for being an excellent source of calcium (28% DV), iron (32% DV), and folate (58% DV), along with good amounts of magnesium and zinc. As a minimally processed food (NOVA 1), it gains an additional +10 points, aligning with dietary guidelines that emphasize whole foods. The primary detractor from a higher score is its elevated sodium content, at 1247mg per 100g, which incurs a -6 point penalty. To improve its score, a lower sodium formulation would be beneficial, as its other nutritional attributes are quite strong.

Health benefits

What the nutrients in cornmeal actually do for you, grounded in established dietary science.

Supports Digestive Health

Cornmeal is a good source of dietary fiber, providing 6.7 grams per 100-gram serving. Fiber is crucial for maintaining a healthy digestive system by adding bulk to stool, which can help prevent constipation and promote regular bowel movements. Research supports that adequate fiber intake is associated with a lower risk of various digestive issues. Including fiber-rich foods like cornmeal can contribute to meeting the recommended daily fiber intake, which is around 25-38 grams for adults, making this food a valuable component for gut regularity.

Contributes to Bone Health

This grain provides 361mg of calcium per 100g, which is 28% of the Daily Value, and 86mg of magnesium, 20% of the Daily Value. Both calcium and magnesium are essential minerals for maintaining strong bones and teeth. Calcium is the primary structural component of bone, while magnesium plays a role in bone formation and helps regulate calcium and vitamin D levels. Dietary guidelines emphasize the importance of consuming sufficient amounts of these minerals throughout life for optimal bone density and to reduce the risk of osteoporosis. Incorporating cornmeal into the diet can help meet these important mineral needs.

Boosts Red Blood Cell Production

Cornmeal is an excellent source of iron, supplying 5.76mg per 100g, which accounts for 32% of the Daily Value. Iron is a vital mineral necessary for the production of hemoglobin, a protein in red blood cells that carries oxygen from the lungs to the rest of the body. Adequate iron intake is critical for preventing iron-deficiency anemia, a condition that can lead to fatigue and weakness. The NIH lists iron as a key nutrient for energy metabolism and overall health, making cornmeal a beneficial food for supporting healthy blood function.

Supports Energy and Metabolism

With 58% of the Daily Value for folate per 100g, cornmeal significantly contributes to the body's needs for this B vitamin. Folate, also known as vitamin B9, is essential for numerous bodily functions, including cell growth and division, and the formation of genetic material. It plays a critical role in energy metabolism and the proper functioning of the nervous system. Dietary guidelines emphasize the importance of folate, especially for individuals of childbearing age, due to its role in preventing certain birth defects. Including folate-rich foods like cornmeal can help ensure adequate intake for these vital processes.

How to eat it

Cornmeal is a versatile grain product, commonly used in American cuisine for dishes like cornbread, polenta, and as a coating for fried foods. It serves as a staple carbohydrate source and can be incorporated into both savory and sweet preparations. When preparing, consider its texture, which can range from coarse to fine, influencing the final dish. A typical serving size might be around 50-100g, depending on the meal and individual dietary needs, often paired with vegetables or lean proteins.

For a healthier cornbread, use whole grain cornmeal and reduce added sugar and fat in the recipe.
Incorporate cornmeal into savory dishes like polenta, pairing it with lean protein and plenty of vegetables for a balanced meal.
When using cornmeal as a breading, opt for baking or air-frying instead of deep-frying to reduce added fats.
Store cornmeal in an airtight container in a cool, dark place to maintain freshness and prevent spoilage.
Things to keep in mind

Cornmeal is generally safe for consumption by most individuals. As a grain, it is naturally gluten-free, making it a suitable option for those with celiac disease or gluten sensitivity. However, individuals with a corn allergy should avoid cornmeal. Due to its high fiber content, some people unaccustomed to a high-fiber diet might experience mild gastrointestinal discomfort, such as bloating or gas, if consumed in very large quantities. Gradually increasing fiber intake can help the digestive system adjust.

Reader questions
Is cornmeal healthy?
Yes, cornmeal is a nutritious grain that can be part of a healthy diet. It scores 78/100 on FoodScore, indicating it's a very good choice. It's particularly rich in fiber, calcium, iron, and folate, which are essential nutrients for various bodily functions. However, some preparations can be high in sodium, so it's important to choose or prepare it wisely.
Is cornmeal good for weight loss?
Cornmeal can be good for weight loss due to its fiber content (6.7g per 100g), which promotes satiety and can help you feel full longer, potentially reducing overall calorie intake. It's also a source of complex carbohydrates, providing sustained energy. However, portion control is key, as it is calorie-dense at 334 calories per 100g, and preparation methods can significantly impact its calorie and fat content.
Is cornmeal ultra-processed?
No, cornmeal is considered a minimally processed food, classified as NOVA 1. This means it undergoes minimal processing, such as grinding, without the addition of sugars, fats, or other food substances that characterize ultra-processed foods. It retains most of its natural nutritional integrity.
How should I cook cornmeal to maximize its health benefits?
To maximize health benefits, cook cornmeal with minimal added sodium, sugar, and unhealthy fats. For example, prepare polenta with water or low-sodium broth and serve it with plenty of vegetables and lean protein. When making cornbread, opt for whole grain varieties and reduce the amount of added sugar and butter in the recipe.
What are some healthy substitutions for cornmeal?
For a similar texture and nutritional profile, you can substitute cornmeal with other whole grain flours like whole wheat flour, oat flour, or even almond flour for gluten-free options, depending on the recipe. Each substitute will alter the flavor and texture slightly, but can offer comparable fiber and micronutrient benefits.
Does cornmeal contain gluten?
No, cornmeal is naturally gluten-free. It is derived from corn, which does not contain gluten proteins. This makes it a suitable grain option for individuals with celiac disease or gluten sensitivity, provided there is no cross-contamination during processing.
Is cornmeal good for heart health?
Cornmeal can contribute to heart health, primarily through its fiber content. Dietary fiber helps manage cholesterol levels and blood pressure, both important for cardiovascular well-being. However, it's important to be mindful of its sodium content (1247mg per 100g) in some preparations, as high sodium intake can negatively impact heart health. Choosing low-sodium versions or preparing it without added salt is advisable.
