Popcorn is a popular snack, especially at the movies, and is generally considered a whole-grain, fiber-rich snack. While plain corn is gluten-free, and popcorn is made from corn kernels, the potential for gluten cross-contamination arises during processing and from gluten ingredients in flavorings. For those with celiac disease or non-celiac gluten sensitivity, it is important to be aware of gluten-free options and brands that pose a risk for cross-contamination.

Corn is gluten-free, but flavourings may not be
Corn is a gluten-free grain, and plain popcorn is naturally gluten-free too. However, some flavourings and toppings may contain gluten, and there is also a risk of gluten cross-contamination during the processing of the corn. Therefore, it is important to carefully check the ingredients and preparation methods of flavoured popcorn products to ensure they are gluten-free.
Some brands, such as Arrowhead Mills, offer a variety of gluten-free products, but their white and yellow popcorn do not appear on their gluten-free list. This could be due to a risk of cross-contamination, which is a concern for those who are highly sensitive to gluten. Bob's Red Mill, a popular manufacturer of gluten-free products, has built a separate facility to prepare gluten-free products and batch tests all products in a controlled laboratory to protect consumers from accidental cross-contamination.
Many companies offer gluten-free flavoured popcorn products. Angie's, a subsidiary of ConAgra, offers a wide variety of interesting flavours that are certified gluten-free by the Gluten-Free Certification Organization (GFCO). Act II, another ConAgra brand, offers ten flavours of microwavable popcorn that are considered gluten-free, with less than 20 parts per million of gluten. Smartfood Popcorn, the self-proclaimed favourite popcorn brand in America, sells several flavours of ready-to-eat bagged popcorn, four of which are gluten-free, including white cheddar and sea salt.
For those who enjoy making their own flavoured popcorn at home, it is important to ensure that all ingredients added are gluten-free. For example, gluten-free dry ranch seasoning can be combined with parmesan cheese, dried parsley, and onion powder, and then stirred into melted butter to create a delicious gluten-free topping for popcorn.

Cross-contamination is a risk in some brands
While plain corn is gluten-free, and popcorn is just popped corn, it is possible to consume gluten when eating popcorn without knowing it. The problem with popcorn is the potential for gluten cross-contamination in processing and gluten ingredients in the flavourings used to make popcorn more interesting. Popcorn made in facilities that also manufacture glutenous foods may be at risk for cross-contamination.
Some common gluten-containing additives include malt flavouring, wheat starch, brewer's yeast, and soy sauce. Popcorn may be at risk for gluten cross-contamination depending on where it's manufactured. Certain popcorn brands may use gluten-containing flavourings or additives. If you're particularly sensitive to trace amounts of gluten, choosing a popcorn without additives or flavourings is a good idea.
Look at the ingredient list and choose a product that lists only "popcorn" or contains only corn kernels and salt. It's also a good idea to select products that are labelled certified gluten-free. The Food and Drug Administration (FDA) stipulates that products labelled gluten-free must contain fewer than 20 parts per million (ppm) of gluten. In addition, manufacturers are required by law to indicate common food allergens, including wheat, on the label.
Some brands that offer gluten-free products include Angie's, Act II, Black Jewell, and Great Northern.

Some brands to be wary of include Arrowhead Mills and NOW Foods
While there is no definitive answer to whether Conn's cheese popcorn is gluten-free, some brands to be wary of when looking for gluten-free products include Arrowhead Mills and NOW Foods.
Arrowhead Mills offers a variety of gluten-free products, including an all-purpose flour substitute. However, customer reviews suggest that this product may not be suitable for all baking needs. Some customers have reported that the flour does not bake properly, resulting in a thick, gummy, and goopy consistency. It is important to note that this specific product may not be suitable for traditional baking recipes and may require adjustments or alternative ingredients to achieve the desired results.
On the other hand, NOW Foods is another brand that offers gluten-free products, but it has faced lawsuits alleging that some of its products contain gluten. The lawsuits specifically mention the presence of gluten in their 'Gluten Digest' enzyme product, which is intended to help break down gluten during digestion. The presence of gluten in a product marketed as gluten-free can be concerning for individuals with gluten intolerance or celiac disease.
When it comes to gluten-free options, it is always important to read labels, check ingredients, and be cautious of brands that have received mixed reviews or faced controversies related to gluten content. It is also worth noting that gluten-free products may vary in quality and performance, and some may require adjustments to recipes or baking techniques.
