What is popcorn?

Popcorn is a special type of corn that “pops” when exposed to heat.

At the center of each kernel is a small amount of water, which expands when heated and eventually causes the kernel to explode.

The oldest piece of popcorn was discovered in New Mexico and is said to be over 5,000 years old.

Over the years, it has become increasingly popular. It became especially popular during the Great Depression because it was so cheap.

Today around 1.2 billion pounds (500 million kg) are consumed by Americans every year, making it America’s most popular snack food by volume.

Summary: Popcorn is a special type of corn that “pops” when exposed to heat. By volume, it is the most popular snack food in America.

Popcorn is high in polyphenol antioxidants

Polyphenols are antioxidants that help protect our cells from damage by free radicals.

A study done at the University of Scranton showed that popcorn contains very large amounts of polyphenols.

Polyphenols are linked to various health benefits. This includes better blood circulation, improved digestive health, and a reduced risk of many diseases.

Several studies have also shown that polyphenols may reduce the risk of cancer, including prostate and breast cancer.

Summary: Popcorn contains large amounts of polyphenol antioxidants. These are plant compounds that have been linked to many health benefits.

Popcorn is extremely high in fiber

According to research, dietary fiber may reduce the risk of many diseases like heart disease, obesity, and type 2 diabetes.

Fiber can also help with weight loss and promote digestive health.

The recommended daily intake of fiber is 25 grams for women and 38 grams for men. However, most people are eating much less than that.

100 grams (3.5 ounces) of popcorn contain 15 grams of fiber, which goes a long way towards satisfying your daily fiber requirements.

Summary: Popcorn is very high in fiber, which has been linked to several health benefits. This includes weight loss and a decreased risk of many diseases.

With 31 calories per cup, air-popped popcorn contains much fewer calories than many popular snack foods.

One study compared feelings of fullness after eating popcorn and potato chips. They found that 15 calories of popcorn were as filling as 150 calories of potato chips.

Because of its low calorie content, low energy density, high fiber content, and increased satiety, eating popcorn may help you eat fewer calories and lose weight.

However, moderation is key. Even though it is much more filling than many other snack foods, it can still be fattening if you eat too much of it.

Summary: Popcorn is high in fiber, relatively low in calories, and has a low energy density. Eating it in moderation may help with weight loss.

Pre-packaged microwave popcorn may be harmful

There are many ways to enjoy popcorn, but the most convenient and most popular tends to be the pre-packaged microwave variety.

Most microwave bags are lined with a chemical called perfluorooctanoic acid (PFOA), which has been associated with a variety of health problems.

These include ADHD, low birth weight, and thyroid problems, to name a few.

Microwave popcorn may also contain diacetyl, which is a chemical found in artificial butter flavoring.

Although the risk to the general public has not been identified, animal studies continue to show that breathing in diacetyl can damage airways and cause lung diseases.

Many brands of microwave popcorn are made using hydrogenated or partially-hydrogenated oils, which contain harmful trans fats. Studies have linked trans fats to an increased risk of heart disease and other serious diseases.

Even if certain brands say they are free of these chemicals, you may still want to avoid them since it’s so easy to make your own healthy popcorn.

Summary: Pre-packaged microwave popcorn often contains PFOA and diacetyl, chemicals that may be harmful. It may also contain unhealthy trans fats.

Some toppings and preparation methods are a bad idea

Despite all of popcorn’s healthy qualities, the way it is prepared can greatly impact its nutritional quality.

When air-popped, it is naturally low in calories, but some ready-made types are extremely high in calories.

For example, a report by CSPI found that a medium-sized popcorn at a popular movie theater chain had a whopping 1,200 calories – even before factoring in the buttery topping!

Varieties bought from movie theaters or stores are often smothered in unhealthy fats, artificial flavorings, and high amounts of sugar and salt.

These ingredients not only add a significant amount of calories, but some of them can also be bad for you in other ways.

Summary: Commercially prepared popcorn varieties can be extremely high in calories and unhealthy ingredients.

How to make healthy popcorn

Popcorn made on the stove or in an air-popper is going to be the healthiest option.

Here’s a simple recipe to make healthy popcorn:



  1. Place oil and kernels into a large pot and cover it.
  2. Cook over medium-high heat for about 3 minutes or until the popping almost stops.
  3. Remove from heat and pour into a serving bowl.
  4. Season with salt.

You can add additional flavor by topping it with fresh herbs or spices. If you want something sweet, try drizzling it with natural nut butter or sprinkling it with cinnamon or shavings of dark chocolate.

For an added health benefit, sprinkle it with nutritional yeast. Nutritional yeast has a cheesy flavor and contains several important nutrients, including protein, fiber, B-vitamins, and several minerals.

Summary: The healthiest way to make popcorn is in a pot or air-popper machine. There are several ways to add flavor without compromising its healthfulness.

Real popcorn is super healthy
