The more fibre the better

The more fibre, the better. There are divergent views as to the requirement of dietary fibre for good health. There is no recommended daily dietary allowance for it and hardly any data about optimum amounts. Some Africans known for lower incidence of degenerative diseases take about 150 grams of fibre a day. In Europe and North America, where there is a high incidence of such diseases, people take 25 grams or less a day. Dr. John H. Cummings, a noted fibre expert in England, considers that a fibre intake of 30 grams (about one ounce) per day is sufficient for good health. Excessive consumption of fibre, especially bran, should however, be avoided. Due to its content of crude fibre, bran is relatively harsh and it may irritate the delicate functioning of the digestive system, especially in the sick and the weak. Excessive use of fibre may also result in loss of valuable minerals like calcium, phosphorus, magnesium and potassium from the body through excretion due to quick passage of food from the intestine.
