Popcorn is a snack that can be enjoyed as a healthy treat if prepared correctly. According to [1], one cup of popped popcorn contains 6.2 grams of carbohydrates, 1.2 grams of which come from fiber. The fiber in popcorn not only helps keep you full for relatively few calories, but it can also help promote weight loss. [2] also states that popcorn contains lots of fiber and antioxidants, which can help prevent some serious health conditions.However, it is important to note that the nutritional value of popcorn can vary depending on the preparation method. [3] states that popcorn contains a lot of fiber, vitamins, and minerals when it is air-popped, unsweetened, or unsalted. However, adding a lot of butter, sugar, and salt can make popcorn unhealthy. So, to eat popcorn safely, it's best to avoid adding too much butter, sugar, and salt and opt for air-popped, unsweetened, or unsalted popcorn.
