Corn is one of the most beloved foods there is, but the question always comes up how to treat it. On one hand it looks like a vegetable in every way, but on the other hand it belongs to the grain family. So here’s the deal: Corn is an excellent carbohydrate that can easily replace rice or pasta in a meal, and it has many nutritional benefits worth getting to know up close.
Calories per 100 grams: Let’s talk numbers. In 100 grams of cooked corn kernels (that’s about half a cup or a medium cob) there are about 90 to 95 calories.
For comparison, in the same amount of cooked rice there are about 120 calories. This means that corn is a relatively “light” carbohydrate in calories that allows you to eat a larger volume of food for the same caloric cost. Most of the calories come from carbohydrates, of which there are about 19 grams per 100 grams of corn.
Dietary fiber: The secret to satiety and digestion, corn excels in its fiber content. In 100 grams of corn there are about 2.5 grams of dietary fiber. These are mainly “insoluble” fibers, which are responsible for moving food through the digestive system and preventing constipation. These fibers are what create a prolonged feeling of fullness, because they slow down the rate of stomach emptying and make us feel full for much longer after the meal.
Vitamins: What’s inside and in what quantity? Corn is rich in B-group vitamins, which are the fuel of metabolism in the body. Here are the main figures per 100 grams of corn:
Vitamin B3 (niacin): It contains about 1.7 mg, which is about 10% of the recommended daily intake. It is very important for skin health and the nervous system.
Vitamin B1 (thiamine): It contains about 0.15 mg, which is about 12% of the daily intake. It helps the body convert carbohydrates into available energy.
Vitamin B9 (folic acid): There are about 40 mcg, which is about 10% of the daily intake. Essential for the production of new cells in the body.
Vitamin C: There are about 6 mg, which is close to 10% of the daily requirement, which helps strengthen the immune system.
Minerals – support for muscles and blood pressure: In the mineral department as well, corn does not disappoint and provides good protection for the body:
Magnesium: In 100 grams of corn there are about 37 mg of magnesium, which is about 10% of the recommended intake. Magnesium is critical for muscle relaxation and bone health.
Potassium: There are about 270 mg of potassium, which is about 6% of the daily requirement. It helps balance salt levels in the body and maintain normal blood pressure.
Phosphorus: There are about 90 mg, which is about 12% of the daily allowance, very important for the health of teeth and bones.
Corn versus rice and wheat: When comparing corn to other common carbohydrates like white rice or white wheat products, corn wins by a mile. White rice has less fiber and more calories compared to the same amount of corn. Unlike wheat, corn is also naturally gluten-free, which makes it an excellent solution for people with sensitivity. In addition, the glycemic value of corn is lower compared to white bread or rice, which means that blood sugar rises more moderately after eating it.
Corn flour versus cornstarch – don’t get confused: Many people think corn flour and cornstarch are the same thing, but there is a huge difference between them. Corn flour is produced by grinding the whole kernel, and therefore it preserves the yellow color and the nutritional values mentioned. In contrast, cornstarch is only the starch of the corn without the peel and fiber. Therefore, cornstarch is mainly an empty carbohydrate used for thickening, while corn flour is a whole and much more nutritious food.
Canned corn – is it healthy? The good news is that canned corn usually does not contain preservatives, because the heat sterilization process does the job. It is very important to look at the ingredient list. There are products that add sugar to improve the taste, which raises the caloric value unnecessarily (sometimes an addition of 20–30 calories per serving). Today it is easy to find canned corn without any added sugar at all, which contains only corn, water and salt – this is the preferred and healthier choice.
The secret of digestion: Why is it important to chew? There is one fact about corn that always makes people laugh but it is very important for dieting. The outer shell of the corn kernel is made of cellulose, a type of fiber that our body does not know how to break down.
If we do not chew the kernels well, they simply pass through the digestive system whole and come out exactly as they went in. The meaning is that if we did not chew well, the body did not absorb the calories and carbohydrates inside. Therefore, someone who eats corn quickly without chewing actually gets far fewer calories from the portion, although the nutritional values are also not absorbed in that case.... But of course there is no recommendation here to swallow without chewing.. In order to enjoy the vitamins and minerals, it is worth investing in chewing.
Corn cob – the perfect snack for these days: Precisely now, when we are looking for comfort in food and the tension is at its peak, a hot corn cob is the happiest solution there is. It gives us the comforting carbohydrate “bite” we need, but does so in a healthy, nutritious and relatively low-calorie way compared to other snacks.
Beyond the nutritional values, the act of eating corn is slow and keeps us occupied, which helps relieve stress and create a moment of quiet within the noise.
How to prepare easily? The simplest and most delicious: Cook the cobs in boiling water with a little salt for about 10 to 15 minutes (depending on freshness). Those who want to upgrade and preserve maximum vitamins can roast the corn in its husk on a grill pan or in an air fryer for a few minutes, until it gets a browned color and a slightly smoky taste. This is a snack that always brings a smile, reminds us of the flavors of home, and gives the body exactly what it needs to keep going.
