If your diet is like the average American s, you don t get enough fiber. You should consume between 20 and 35 grams of fiber each day, according to the Harvard School of Public Health, but many people don t get more than 15 grams. Fiber helps you digest your food efficiently, which helps your body absorb the nutrients from your food. Getting enough fiber can keep you from getting constipated as well. One cup of pumpkin puree provides you with 7.1 grams of dietary fiber. Pumpkin puree contains about 10 percent of your daily requirement for potassium as well. You need adequate amounts of potassium to support healthy digestion.
