We have all heard that popcorn is the least fattening of the snacks to eat (probably because its less processed) but I wondered about digestion. Best article I found on Livestrong.com.....here is an excerpt, I've saved you time by underlining some key issues:
When food enters your digestive tract, it is converted into an absorbable nutrient. Some parts of popcorn are more easily absorbed than others. Popcorn is considered a whole-grain food source, meaning it contains the entire grain kernel. Whole grains are rich in minerals, vitamins and fiber, derived from the bran, endosperm and germ parts of the grain. While popcorn is naturally a low-calorie snack, adding butter, oil and other types of toppings increases the amount of calories and fat you consume.
Fiber in Popcorn
High-fiber foods, such as fruits, vegetables and whole grains, provide both soluble and insoluble fiber, but they usually have higher amounts of one over the other, according to the Linus Pauling Institute. Popcorn is a source of insoluble fiber that travels through your gut relatively intact without breaking down. Insoluble fiber from popcorn sweeps through your digestive tract, pushing food along, increasing fecal bulk and keeping you regular. While fiber is an edible part of plant foods such as popcorn, it cannot be digested.
Fiber in the Diet
Women need 25 grams of dietary fiber daily, and men need as much as 38 grams, but the average diet in the United States only provides about half of these amounts. Increase your fiber intake by consuming the recommended 3 to 4 ounces or equivalents of grain servings daily. One serving of popcorn is equivalent to a 3-cup portion, reports MyPyramid.gov. Popcorn provides a little more than 1 gram of fiber per cup. If you are not used to consuming high-fiber foods, gradually increase your intake over a few weeks. Since fiber is not digested, adding too much fiber from popcorn and other sources all at one time can cause intestinal distress, such as gas, bloating, constipation and diarrhea.
