why are there calories in soluble fiber

Every healthy diet should contain water-soluble and insoluble fiber. The recommended daily intake for fiber is 14 grams per every 1,000 calories you consume.

This comes to an average of 25 grams of fiber for adult women and 38 grams of fiber for adult men. However, the “Dietary Guidelines for Americans 2010” reports that the typical American diet contains only around 15 grams of fiber per day.

This suggests you should evaluate your daily fiber intake to ensure you are getting the recommended level every day.
