Is Popcorn Gluten-Free?

Reading Time: 4 minutes

Whether you’re indulging in this savoury snack during a movie night, enjoying it on a road trip or savouring it as an afternoon pick-me-up, popcorn holds a special place in the hearts of many. Not only does it tantalise the taste buds, offering a one-of-a-kind soft and crunchy experience, crafted from a specific variety of corn kernels that expand when heated.

Popcorn, being a whole grain, provides a rich supply of essential vitamins and minerals like niacin, iron, phosphorus, magnesium, zinc and manganese. However, its status as a reliable gluten free option is a bit grey and might raise questions in the minds of those with serious gluten intolerances, wheat allergies or celiac disease.

So the question remains: Is popcorn gluten free?

This article explains whether all popcorn is gluten-free and offers tips for choosing one that is.

First, what is popcorn?

An ancient relic of popcorn was uncovered in New Mexico, with an estimated age exceeding 5,000 years. Popcorn is made from a distinctive variety of corn that undergoes a “popping” transformation when heated. Enclosed within each kernel lies a modest quantity of water, which expands when exposed to heat and ultimately triggers the kernel to burst open. Over time, this snack has gained surging popularity, particularly during the Great Depression due to its affordability. Today, no movie experience is complete without a bucket of popcorn to munch on.

Second, what is gluten?

Before delving into the specific gluten content of popcorn, it’s imperative to to understand what gluten really is. Gluten, a protein, is present in wheat, barley, rye and triticale. If you suffer from celiac disease or minor gluten intolerances like non-celiac gluten sensitivity or a wheat allergy, gluten can prompt your immune system to damage the delicate lining of your small intestine, eventually hindering the absorption of nutrients from your diet or manifest as a spectrum of symptoms, encompassing gas, cramping, headaches, depression and anaemia, among others.

Most popcorn is gluten free

In summary, unadulterated popcorn is inherently gluten-free, making it a safe and appealing choice for individuals managing celiac disease and non-celiac gluten sensitivity. However, it’s essential to exercise caution when selecting store-bought popcorn, as not all products are guaranteed to be gluten-free. The potential issue doesn’t lie with the corn itself, as corn is generally recommended as a gluten free safe alternative. Rather, the concern stems from the processing methods and the risk of cross-contamination with gluten-containing ingredients. Additionally, some store bought popcorn brands may have flavourings or seasonings that contain gluten.

Thankfully, many prominent popcorn brands clearly label their products as “gluten-free,” simplifying safe shopping.

Some popcorn products may contain gluten

While most popcorn is naturally devoid of gluten, it’ll serve you well to be cautious due to cross contamination with glutinous grains. Popcorn produced in facilities that also handle gluten-containing foods is more often than not cross-contaminated. Moreover, popcorn that has been seasoned with certain flavourings and additives can contain gluten. Common gluten-containing toppings include malt flavouring, wheat starch, meat substitutes, rice syrup, brewer’s yeast, spice blends and soy sauce which generally contain gluten.

Corn allergies are possible but rare

Corn, including popcorn, is generally considered a safe dietary choice for the majority of us. However, in rare instances, some people may exhibit adverse reactions to corn. If you find yourself constantly experiencing these symptoms after eating corn or popcorn, chances are that you suffer from a corn allergy and need to eliminate it from your diet.

Symptoms of a corn allergy often overlap with those of gluten intolerances-  nausea, vomiting, and diarrhoea. Seeking medical guidance can help determine whether your symptoms are a corn allergy.

How to ensure your popcorn is gluten free

If you’re particularly sensitive to gluten, choosing a popcorn brand without additives or flavourings is a good idea. Be sure to carefully look at the ingredient list before choosing a specific popcorn brand. It’s also a good idea to select products that are labelled certified gluten-free. Even better is if you find popcorn with a third-party gluten-free certification.

How to make your own gluten free popcorn

Popping your own gluten-free popcorn is pretty straightforward.  All that’s required are unprocessed popcorn kernels, heat and some salt for seasoning. Preparing your popcorn from scratch offers a reliable way of guaranteeing its gluten-free status. Whether you opt for a popcorn air-popper, a microwave or a stovetop pan, making gluten-free popcorn at home is a hassle-free process. So much easier than you might imagine!

How to make gluten-free popcorn in the microwave:

• In a brown paper bag, add 1/3 cup (75 grams) of popcorn kernels.
• Fold the top of the bag a few times to prevent the kernels from falling out and place the bag in the microwave and cook on high for 2.5–3 minutes.
• Leave the bag in the microwave for 1–2 minutes to cool.
• Carefully remove it from the microwave and enjoy your popcorn straight out of the bag or pour it into a large serving bowl.
• You can season it with salt, butter, or other gluten-free seasonings.

How to make popcorn on your stovetop:

• Place 2 tablespoons (30 ml) of high-heat oil, such as avocado oil, in a large stovetop pan.
• Add 2–3 popcorn kernels. Turn the heat on high. Once you hear the kernels pop, remove the pan from the heat and add the remaining unpopped kernels (½ cup).
• Cover the pan and let it sit for about 2 minutes.
• Place the pan back on the stove on high heat and allow the remaining kernels to pop. Shake the pan occasionally to help with even heating.
• Once the popping slows down, remove the pan from the heat and let it sit for a couple of minutes in case any remaining kernels pop.
• Pour your popcorn into a large serving bowl and sprinkle some salt, butter or another gluten-free seasoning of your choice.

 Gluten free popcorn seasonings

Some store bought popcorn seasoning mixes may contain gluten. Read the label carefully when shopping. Possible options for gluten-free popcorn toppings include butter, olive oil, salt, pepper, chilli flakes, parmesan cheese, garlic powder, cinnamon, sugar, coconut oil and cocoa powder to name a few.

 The bottom line

Popcorn is gluten free, if it is free of contamination. Always read the labels on popcorn packets if you do have gluten sensitivities. On the whole, popcorn is a fibrous gluten free snack that most of us love and enjoy!
