Fiber also called as roughage forms the part of plant based foods. Body is not able to digest it so it passes through the digestive system and makes the bulk of stool. It keeps the digestive system clean and eases bowel movements.
The daily required intake of fiber is 25-30 grams. Many people do not take this much fiber hence suffer from problems like constipation, upset stomach etc. But crossing the threshold of 70 grams of fiber can also lead to another set of problems like:
bloating
gas
dehydration
poor absorption of some nutrients like calcium, zinc, iron and magnesium because they bind with the fiber which hinders the absorption process.
