Are you getting enough fiber? If so, you are in the minority as several studies have indicated that as many as 86% of Americans do not include enough fiber in their diets. The American Dietetic Association's has stated that when populations consume more dietary fiber, their chronic disease levels are lower. They recommend consumption of 14 grams of dietary fiber per 1,000 calories, or 25 grams per day for adult women and 38 grams per day for adult men. Unfortunately, the average daily intake of dietary fiber in the United States is only 14 grams per day.
