What are some of the known issues related to overconsumption of fiber?

Answer 1

Answers may vary. The Institute of Medicine recommends that adults consume at least 14 g of dietary fiber per 1,000 kcal. The average daily intake of fiber in the United States is about half this amount. Most experts agree that a diet high in fiber is beneficial to one's health and carries minimal adverse effects. While some fibers may have a tendency to bind minerals such as calcium, zinc, iron, and magnesium, it is doubtful that the consumption of dietary fiber in recommended amounts affects mineral status in healthy adults. A sudden and/or large increase in fiber intake may cause a gastrointestinal problem such as diarrhea or constipation. As such, a person should increase his or her fiber intake gradually and give the body time to adjust. It is also wise to increase fluid intake as one increases fiber-this can help alleviate common problems such as constipation.
