When you think about cooked grains, your mind likely drifts towards staples like oatmeal, rice, or quinoa. However, corn is frequently underestimated, yet it can also be relished as a delightful cooked grain side dish or breakfast cereal, particularly when transformed into cornmeal. One popular dish is polenta, which is created by simmering ground cornmeal in salted water. As the cornmeal absorbs the liquid, it becomes tender and evolves into a creamy, porridge-like consistency, making it a comforting option for any meal. To elevate the flavor, consider incorporating herbs, spices, or even grated cheese, which can enhance its taste profile significantly. Originating from Northern Italy, polenta is not only economical and easy to prepare but also incredibly versatile, making it a dish worthy of exploration in your culinary repertoire.

This article delves into the nutritional aspects, health benefits, and various uses of polenta, shedding light on why it deserves a place in your kitchen.

Nutrition Facts of Polenta

Plain polenta, which is prepared without any cheese or cream, is relatively low in calories and provides only minor amounts of various essential vitamins and minerals. Similar to other grains, it serves as a valuable source of carbohydrates.

A typical serving size of polenta cooked in water, approximately 100 grams (about 3/4 cup), contains the following nutritional information:

• Calories: 80
• Carbohydrates: 17 grams
• Protein: 2 grams
• Fat: less than 1 gram
• Fiber: 1 gram

Pre-cooked polenta is also available in convenient tube packaging. If the ingredients list comprises solely water, cornmeal (makki ka aata), and possibly salt, then the nutritional profile should remain consistent. Most commercially packaged and pre-cooked polenta is derived from degerminated corn, indicating that the germ—the innermost section of the corn kernel—has been removed. Consequently, it does not qualify as a whole grain product. The germ contains a significant amount of fat, B vitamins, and vitamin E, so its removal leads to a decrease in these vital nutrients. This process also extends the shelf life of packaged polenta or degerminated cornmeal, as there is less fat available that can spoil. For those seeking a more nutritious option, creating polenta with whole grain cornmeal is recommended; simply check for “whole corn” on the ingredient label.

Cooking polenta in milk instead of water can enhance its nutritional content, though it will also elevate the calorie count. Much like rice, polenta is frequently utilized as a side dish or a base for various meals. Due to its low protein and fat content, it pairs beautifully with meats, seafood, or cheese, transforming it into a more balanced meal. Polenta is a traditional Italian dish resembling porridge, made by simmering cornmeal in water and salt. Despite being high in carbohydrates, it maintains a moderate caloric value. To boost fiber and nutrient levels, opt for whole grain cornmeal instead of its degerminated counterpart.

Is Polenta Healthy?

Corn (makka), a vital cereal crop globally, serves as a staple grain for around 200 million individuals. While cornmeal itself lacks a comprehensive nutrient profile, when combined with other nourishing foods, it can certainly find its place in a balanced diet.

Rich in Complex Carbohydrates

The variety of corn used to produce cornmeal and polenta differs significantly from the sweet corn enjoyed during summer barbecues. This type is starchier field corn, abundant in complex carbohydrates. Complex carbs are digested at a slower pace compared to simple carbohydrates, assisting in prolonged satiety and delivering sustained energy throughout the day.

Within starch, we find two forms of carbohydrates: amylose and amylopectin. Amylose, often referred to as resistant starch due to its ability to resist digestion, constitutes approximately 25% of the starch found in cornmeal. This form of carbohydrate is linked to improved blood sugar and insulin management, while the remaining starch is primarily made up of amylopectin, which is easily digestible.

Moderately Blood Sugar Friendly

The glycemic index (GI) measures how much a particular food can elevate blood sugar levels on a scale of 1 to 100, whereas the glycemic load (GL) considers serving size to assess the food's impact on blood sugar. Although polenta is rich in starchy carbohydrates, it boasts a moderate GI of 68, indicating that it should not cause a rapid spike in blood sugar levels. Additionally, its low GL suggests it will not lead to significant blood sugar spikes after consumption.

However, it's crucial to remember that the GI and GL of foods can vary based on what you consume alongside them. For individuals managing diabetes, the Diabetes Canada guidelines recommend focusing on the overall carbohydrate content of meals rather than solely on glycemic measurements of individual components. Therefore, it is advisable to enjoy polenta in smaller portions—around 3/4 cup (125 grams)—paired with nutrient-dense foods like vegetables and proteins to achieve a balanced meal.

Packed with Antioxidants

Polenta, made from yellow cornmeal, serves as a significant source of antioxidants—compounds that protect the body’s cells from oxidative stress and may lower the risk of certain age-related illnesses. The primary antioxidants present in yellow cornmeal include carotenoids and phenolic compounds.

Carotenoids such as carotenes, lutein, and zeaxanthin not only impart the yellow hue to cornmeal but also contribute to a reduced likelihood of developing eye conditions like age-related macular degeneration, alongside lower risks of heart disease, diabetes, cancer, and dementia. Meanwhile, phenolic compounds, which encompass flavonoids and phenolic acids, add to the flavor profile of cornmeal with their sour, bitter, and astringent notes. These compounds are believed to lower the risk of age-related diseases through their antioxidant properties and contribute to reducing inflammation in the body and brain.

Gluten-Free Alternative

Corn, and consequently cornmeal, is inherently gluten-free, making polenta an excellent grain option for those adhering to a gluten-free lifestyle. Nevertheless, it is prudent to scrutinize ingredient labels carefully, as some manufacturers might incorporate gluten-containing additives, or the product could be produced in facilities that handle gluten-containing foods, raising the potential for cross-contamination. Many brands proudly declare their polenta as gluten-free on the packaging.

How to Prepare Polenta

Polenta is a wonderfully simple dish to make, perfect for both novice cooks and seasoned chefs. To prepare a delicious batch of polenta, you'll need one cup (125 grams) of dry cornmeal (makki ka atta) paired with four cups (950 mL) of water, yielding approximately 4–5 cups (950–1188 mL) of creamy polenta. This dish follows a straightforward four-to-one ratio of water to cornmeal, which can be easily adjusted based on your specific requirements.

Here’s a step-by-step guide to create the perfect creamy polenta:

• Begin by bringing 4 cups (950 mL) of lightly salted water or broth to a rolling boil in a suitable pot.
• Once boiling, incorporate 1 cup (125 grams) of packaged polenta or yellow cornmeal.
• Mix it thoroughly, then lower the heat to maintain a gentle simmer, allowing the polenta to thicken beautifully.
• Cover the pot and allow it to cook for about 30–40 minutes, stirring every 5–10 minutes to prevent sticking and burning at the bottom.
• If you opt for instant or quick-cooking polenta, the cooking time drastically decreases to just 3–5 minutes.
• For added flavor, feel free to season the polenta with salt, a drizzle of olive oil, grated Parmesan cheese, or a selection of fresh or dried herbs.

If you wish to try baked polenta, simply transfer the cooked mixture to a baking dish and place it in an oven preheated to 350°F (177°C) for approximately 20 minutes, or until it becomes firm and lightly golden. After baking, allow it to cool before cutting it into squares for serving.

To ensure the longevity of your cornmeal, store it in an airtight container in a cool, dry environment, and always check the best-by date. Typically, degerminated cornmeal has a lengthy shelf life of about one year. On the other hand, whole grain cornmeal is best consumed within three months. For extended storage, consider refrigerating or freezing it.

Once cooked, polenta can be refrigerated and should be consumed within 3–5 days for optimal taste and texture.
