Each check is a yes-or-no fact with its source: a green check means the flag does not apply, an amber mark means it does. The count is not a health score. Our sources and how we check them.

Numbers: USDA FoodData Central, FDC 167959 (Snacks, popcorn, air-popped). Checked October 2026.

What's in it

One ounce (28 g, about 3.5 cups) of air-popped popcorn has 110 calories, 3.7 g of protein, 4.1 g of fiber and about 2 mg of sodium (USDA FoodData Central, FDC 167959). One cup (8 g) has 31 calories, 1.0 g of protein and 1.2 g of fiber. We use the ounce because it is close to the FDA's 30 g reference amount for snacks. Oil, butter, salt and caramel change these numbers, so read the label on microwave and kettle bags for added sugars, sodium and the ingredient list.

For kids 4–8

The AAP lists popcorn among foods to keep from children until age 4 or older, depending on each child's development. The CDC lists it too. When a child is ready, serve a small bowl at the table, sift out unpopped kernels, and skip popcorn in the car or during play.

Swaps and pairings

Popcorn has little protein, so pair it with a protein food: a string cheese stick has 6 g (see our string cheese card), and plain milk or yogurt adds more. Popping kernels at home in an air popper or a covered pot lets you choose the salt and fat.

Store-bought vs homemade

Air-popped popcorn has one ingredient. Flavored store-bought popcorn may list sugar, butter flavor, colors or salt. The Dietary Guidelines for Americans 2025–2030 advise limiting foods with artificial flavors and petroleum-based dyes, and say no amount of added sugars is recommended for children 5 to 10.

Is popcorn healthy for a 5-year-old?

The AAP advises keeping popcorn from children until 4 or older, depending on development, and the CDC also lists it as a choking risk. Plain air-popped popcorn has no added sugar and 4.1 g of fiber per ounce.

Is microwave popcorn healthy?

It depends on the bag. Check the label for added sugars and sodium, and the ingredient list for flavors or colors, which mark a highly processed food under the NOVA system. Plain air-popped popcorn has none of these.

Does popcorn have fiber?

Yes: 1.2 g per cup and 4.1 g per ounce of air-popped popcorn (USDA FDC 167959). The FDA's "good source" level is 10% of the 28 g Daily Value, or 2.8 g.
