What Happens To Your Body When You Eat Popcorn

Is it as healthy as some claim? We turn to the science.
FACT CHECKED BY Kiersten Hickman

There's no better combination than popcorn and a good movie—but what exactly happens to your body when you eat popcorn? Well, the first thing to know is that the effects of popcorn fully depend on how you make it.

If you're buying the popcorn in the theater when it's drowned in butter and salt—you're not doing yourself any health favors. Similarly, if you're going with microwaved popcorn at home, it could be filled with preservatives and unknown ingredients, which leaves too much up to chance. The healthiest popcorn option is air-popped. By making it yourself instead of nuking it in the microwave, you can fully control what goes in it—like a sprinkle of salt instead of the insane amounts in processed popcorn.

Sticking to this healthy way of making this delicious snack will lead to lots of health benefits that microwave or movie theater popcorn never would. So if love to eat popcorn, here's what your body should expect. And if you're looking for even more healthy meal ideas, be sure to check out our list of the 100 Easiest Recipes You Can Make.

You could be lowering your risk of heart disease and diabetes.


We probably all know that popcorn is a type of corn kernel—so the fact that it naturally comes from corn makes it a whole food. A whole grain, to be specific. According to the American Heart Association, whole grains, especially those that have high fiber, as popcorn does, have been linked to a lowered risk of heart disease and diabetes. Just make sure that once your popcorn is air-popped, that you don't go crazy with the seasonings—the key is to lightly season to reap the most health benefits. For inspiration, here are 20 Delicious Ways to Dress Up Your Popcorn.

If you're maybe thinking that eating movie theater popcorn still isn't so bad, we're here to tell you to stay away. The main reason is sodium.

With that amount of sodium, you could be putting yourself at serious risk of hypertension and stroke, so next time you hit the theater, definitely bring your own snacks.
