Popcorn has been a staple snack for a long time, and it’s easy to see why! It only has a few main ingredients, can be cooked in a variety of ways, and it’s delicious and filling! There are even some health benefits to be gained from it, but how does it rate calorie-wise?
A microwaved bag of popcorn has about 535 calories. A large bucket of popcorn from the movies could contain up to 1200 calories. If you look at the number of calories per cup you will find that it is relatively low (only 31 calories). Butter, salt, and sugar in excess change the calorie count.
Most health professionals agree that popcorn in moderation can be a healthy snack. It is low in calories and has a variety of other nutritional benefits. Let’s take a deeper look into what really comes in that bag of popcorn and what seasonings and toppings will add and detract from its overall nutritional value.

As you stroll through the shelf of the grocery store, you will come across many different brands and types of popcorn to choose from. There are brands like Kirkland, Orville, Act II, Jolly Time, Pop Secret, and many many others.
Each of these companies will obviously have different varieties in their popcorn like the basic butter popcorn, kettle popcorn.
There are also brands that advertise a more healthy variety. of popcorn. This could include popcorn with low salt, air pop, low fat, enhanced nutrients, etc. Each of these will also mean a different calorie count due to a slight variation in ingredients.
When it really comes down to it though, the best types of popcorn for your health will be the ones with the shortest ingredient lists. They really are quite long anyway, but the less that is added, the fewer calories there will be.
It will also depend on the oil or butter that is used as well. For example, a microwave popcorn claiming to be low fat will have only about 424 calories per bag.
A microwave bag of popcorn that is made with another type of oil that is more detrimental to your health (known as trans fat) will have about 557 calories in just one bag. Your regular bag of buttered popcorn though will normally have about 535 calories per bag.

In relation to the value of popcorn, people used to think that microwave popcorn contained a chemical that was likely to cause cancer. It was the chemical that was added to prevent the grease and oil from leaking through the packaging, making it impossible to keep for long periods of time.
The popcorn companies have since changed their packaging and have not used this chemical since 2013 when the FDA banned it. This means that the thing that once scared many people about microwave popcorn is no longer a threat. It can be enjoyed without the fear of bad chemicals or harmful add-ins.

Bagged Popcorn follows many of the same principles. Brands of bagged popcorn include Skinny Pop, Smart Food, Trader Joe, Boom Chika Pop, and many others. Each of these has varieties like buttered, white cheddar, or even exotic flavors like birthday cake.
For example, the original skinny pop popcorn has about 150 calories per serving, and there are about 4.4 servings in a bag, meaning that a whole bag of this popcorn would be about 660 calories. Surprisingly, that is even a little more than some of the microwaved popcorn brands we talked about above.
While there may not be much difference for some of the bagged versus the microwaved popcorns, we see in the chart below that each of these popcorns vary in serving size and in calories, making it hard to see exactly what the calorie count is for each one.
Another thing to consider is how the bagged popcorn is cooked. Many can be popped with heat and oil, adding extra calories because of the butter and oil used in the process, while some may be air-popped, meaning they are just using heated air to cause the popcorn to pop with no need for excess oils.
These are normally more healthy and result in fewer calories being consumed.

Say you were also then to add grated parmesan on top. Then you would be adding another 20 calories, 2 grams of protein, 1 gram of fat, and 46 milligrams of sodium.
While we have looked into these toppings and their calorie count there are so many more mixtures that people go to to make popcorn taste the way they like it. You can also add lots of butter and salt, which will take up both the fat and calorie count.
