You may not know it, but popped popcorn is actually chock full of fibre, explains Agyeman. "In fact, the fibre in popcorn is insoluble fibre, which is the bulking fibre that helps keep your bowels moving regularly," she says. Just three cups of popcorn contain four grams of fibre.
To give your popcorn some flavour, consider a sprinkle of nutritional yeast on top. Nutritional yeast not only delivers a nutty taste but also boosts the fibre content of your snack, according to Wilson. "Two tablespoons of nutritional yeast can provide around four to five grams of fibre, which is about 20 percent of your recommended daily intake," she adds.
