Don't worry, fellow vegans; this crunchy, salty, irreplaceable snack is vegan-friendly. Well, at least in its basic form, that is.
Some brands tend to sneak in a couple of ingredients that may not go well with the vegan diet, so let's get into details and discover what you should look out for when choosing your next bag of popcorn.
What Makes Popcorn (Non)Vegan?
Movie-goes' snack of choice is made of corn kernels that pop when heated - and that's how you get a bowl of nice and crispy plant-based snacks.
So, in its essence, plain popcorn is a vegan snack.
Some vegans hesitate to eat popcorn because it is usually served with butter, which is a dairy product.
The addition of artificial flavors or animal-derived flavors is another red flag for vegans.
Also, some brands may use palm oil, which, although plant-based, is but not approved by the vegan community because its production causes a number of environmental problems.
In short, the type of oil used for popping and the absence of toppings that may contain animal ingredients is what makes popcorn suitable for a vegan diet.
Common vegan-friendly ingredients include corn, sunflower, cottonseed, olive oil, sucralose, salt, ascorbic acid (vitamin C), tocopherols (vitamin E), and TBHQ.
On the flip side, you should watch out for ingredients such as: meat flavors (e.g., bacon flavor), natural flavors (these are usually animal-derived - avoid if the product isn't labeled vegan), mono and diglycerides, cheese, milk/milk powder, whey, lactose, and sodium caseinate, refined sugar.
Is It Gluten-Free?
Most unflavored, plain popcorn is safe for gluten-sensitive folks.
"Popcorn is made from corn, which doesn't contain gluten. In fact, corn is often recommended as a safe alternative to wheat for those with celiac disease, and most people who cannot tolerate gluten can safely enjoy corn products." 
Although it's naturally gluten-free, this and other possible allergens can end up in your bag of popcorn during the production process.
Homemade vs. Store-Bought
If you are into homemade popcorn, you can make them from scratch by using just some good-quality corn kernels and a bit of vegetable oil.
Making your own bowl of stovetop popcorn is the foolproof way to ensure your popcorn is vegan; make sure not to burn the kernels.
Microwave popcorn and pre-popped popcorn, on the other hand, may contain some less-than-vegan ingredients.
We'll go over some vegan-friendly popcorn brands in this article, so keep on reading to find out more.
If you are a hard-core popcorn fan, you can get one of these cool devices to make your own vegan popcorn. This is a smart way to control the amount of salt and the type of flavors that end up in your movie-night snack bowl.
Are Popcorns in Movie Theaters Vegan?
Yes and no, depending on the theater. Vegans can sit back, relax and munch on vegan popcorn in most U.S theaters these days:
Don't let the word "butter" printed on the box throw you off because popcorn in most theaters is suitable for a vegan diet:
"At national theater chains like AMC Theaters and Cinemark, popcorn is totally vegan. At AMC Theaters, they even pop gluten-free, trans-fat-free popcorn kernels in coconut oil."

If you head to one of the Regal movie theaters, the chances are that they'll have a vegan version of this iconic snack, but that may not be the case in all of their theaters.
If you are curious about popcorn sold in a specific movie theater, the safest bet is to call before you go and check if their popcorn is vegan.
