Lourdes: Dietary fiber is an important part of a healthful diet. Experts recommend that adults consume 20 to 35 grams of fiber a day. Kyra: But a daily intake of fiber that is significantly above that recommended level interferes with mineral absorption, especially the absorption of calcium. The public should be told to cut back on fiber intake.
The statement 'Among adults, the average consumption of dietary fiber is at present approximately 10 grams a day' most undermines Kyra's recommendation.
