Q: Plants contain indigestible substances in their cell-walls, and these contain fibre. R: Later research has thrown light on many other ingredients that are not digested by man. S: In the early days, people only knew that this fibre prevented constipation. S6: This has resulted in a better appreciation of the role of fibrous food in human health. The Proper sequence should be: A. PQRS B. QSRP C. SPRQ D. SQPR
