Describe the harmful effects of fiber when taken in excess
No Tolerable Upper Intake Level has been established for fiber, but consuming purified fiber added to foods or supplements can be taken to extremes. Too much fiber and too little fluid can overwhelm the digestive system. Approach purified fibers with an attitude of moderation, and be sure to drink an extra beverage with them. Binders in some fibers act as chelating agents. This means that they link chemically with important nutrient minerals (iron, zinc, calcium, and others) and then carry them out of the body. The mineral iron is mostly absorbed at the beginning of the intestinal tract, and excess insoluble fibers may limit its absorption by speeding foods through the upper part of the digestive tract.
