Is Popcorn Gluten-Free? Healthy Snacks In 2024

Popcorn is one of the world’s most beloved snacks, and with its perfect combination of crunch and fluff, how could it not be?  

You can’t even go to a movie theater without your senses being hit by that buttery wave of popcorn. But if you buy it rather than make it at home, it might be full of flavorings and additives. And this poses a risk for people trying to eat healthier or gluten-free. 

It can be healthy^[1] since it’s naturally low in calories and fiber-rich, which means it can aid weight loss. But a gluten-free diet plan is key for people with celiac disease or non-celiac gluten sensitivity. 

So, is popcorn gluten-free? And is it a good snack for people with gluten intolerance? Read on to find out. 

Is All Popcorn Gluten Free?

Plain popcorn is naturally gluten-free since corn doesn’t have gluten.

However, a few brands of pre-packaged popcorn may contain gluten; this can happen through cross-contamination in facilities where other products that contain gluten are made. 

Also, some additives like butter-flavored toppings or ready-to-eat flavors in pre-manufactured popcorn packages may contain trace gluten.

Luckily, some gluten-free brands ensure that traces of gluten are very low.^[2] 

The best way to ensure you’re getting gluten-free popcorn is to make it yourself and avoid processed options — unless they explicitly state they are gluten-free on the package. Why You Might Need Gluten-Free Popcorn

Eating gluten is part of a normal healthy diet, but for people with celiac disease or gluten sensitivity avoiding gluten-containing^[3] ingredients is the best way to prevent inflammation and discomfort. 

A person with celiac disease who consumes gluten^[4] experiences injury to the hair-like lining of the intestines; the symptoms may include abdominal pain, diarrhea, weight loss, or constipation. Other symptoms are also probable and can vary from person to person. A person with a gluten issue will need to follow a strict gluten-free diet. 

However, following a gluten-free diet may require a lot of food modifications. Therefore some people may need to supplement with multivitamins or a gluten-free protein powder. 

A few brands of pre-packaged popcorn may contain gluten; this can happen through cross-contamination in facilities where other products that contain gluten are made. 

Also, some additives like butter-flavored toppings or ready-to-eat flavors in pre-manufactured popcorn packages may contain trace gluten.

Luckily, some gluten-free brands ensure that traces of gluten are very low.^[2] The best way to eat gluten-free is to eat fresh foods rather than heavily processed foods. 

What About Movie Theater Popcorn?

Most unflavored popcorn in a movie theater is generally safe and gluten-free. However, it may contain gluten if it has a buttery topping, flavoring, or additives. 

While real butter is gluten-free, movie theater butter may have additives or flavorings with gluten.

There’s also the concern of the kernels coming in contact with other products sold in theaters that can contaminate the popcorn. 

The best advice to avoid gluten at movie theaters is to check in with the theater before arriving. If you want to be certain, you can also ask for other packaged snacks that state they’re gluten-free on the package.

Finally, you can also request permission to bring your gluten-free popcorn to accommodate celiac disease or gluten intolerance.  

How To Ensure Your Popcorn Is Gluten-Free

Manufacturing companies have specifically labeled gluten-free products in response to consumers increasingly choosing gluten-free products. The foods labeled gluten-free help a consumer make a more informed and safe choice. 

When buying pre-packaged popcorn kernels, check that the package is labeled gluten-free. Most products labeled gluten-free will have a prominent symbol of a circle with a picture of wheat crossed out. They will state if they’re certified gluten-free, meaning a gluten-free certification organization has verified the product. 

The popcorn most likely to have gluten is microwave popcorn; it usually comes with butter and may have additives to stabilize its shelf life. Luckily, because of the growing trend to consume products free of gluten, you can now purchase microwave popcorn labeled gluten-free.  

Finally, the best gluten-free popcorn is the one you can make at home. This option will allow more control of the ingredients added and limit exposure to gluten through the processing and packaging facilities. 

Ways To Make Homemade Gluten-Free Popcorn

Buying your own corn kernels is the best way to get low-fat, gluten-free popcorn. If you don’t add unhealthy ingredients, it can be a helpful addition^[5] to your diet. 

If you like to eat large amounts of snacks without worrying too much about calories, one serving size of 100 calories is 3 cups. You can make popcorn air-popped or in a kettle; either way, you still get 15% of the daily recommended fiber. 

Air-Popped Popcorn 

Homemade gluten-free popcorn is the best way to control ingredients and decrease the possibility of gluten cross-contamination. Air-popped popcorn is easy to make and doesn’t require a particular gadget, but buying an air popper might help. Any way you choose to make the air-popped popcorn will work. 

• Specialty air-popped popcorn machine.
• A non-stick stove top pot.
• Paper bag in the microwave.

Kettle Corn

If plain air-popped popcorn isn’t for you, you can go for kettle corn. Usually, you can get this type of corn at the county fair, but you can also make it at home. Traditionally it was popcorn made in cast iron kettles.  

You can make sweet or salty kettle corn with three simple ingredients: popcorn kernels, oil, and sugar or salt. Add the oil to the kettle over medium heat, add the sugar or salt and popcorn kernels, and mix and cover. Watch the kernels pop, and enjoy with a bit of extra butter or a little more salt.    

The Bottom Line

So, is popcorn gluten-free? 

Yes, popcorn is gluten-free; but store-bought popcorn can have cross-contamination by being made in facilities that process products with gluten. Also, store-bought pre-packaged popcorn can include additives and gluten flavorings. 

You can counter this by purchasing gluten-free popcorn brands or making air-popped popcorn or homemade corn on a kettle. 

You can also verify that popcorn at movie theaters has gluten-free popcorn toppings by calling ahead and verifying if their popcorn is considered gluten-free.

Snacking on popcorn can be a good option and even healthy, but because it’s not an everyday snack, it may not always be considered an issue for a person avoiding gluten. 

Reading nutrition facts labels can help verify if the product is made with gluten or contains traces of gluten.
