About the book

Dietary fiber, also known as roughage, is the portion of plant-derived food that cannot be completely broken down by human digestive enzymes. It has become an important component of the human diet recently due to its many functional properties especially owing to the effect on gut metabolism and health.

This book is aimed at providing an insight into the properties of dietary fiber - what makes it a special nutrient, its chemical characteristics, methods of analysis and the impact on gut activity, i.e. behavior as a pre-biotic for gut microbiota. It is hoped that the book will serve as an update when it comes to recent research, highlighting gaps and voids in previous research as well as setting a new direction towards studies to be conducted in the future. Not just for the scientific readership, the book is aimed to target even the non-expert so that awareness can spread among general consumers on the importance of incorporating dietary fibers into the everyday diet.

Introducing your Author Service Manager

Ms. Marijana Francetic

As an Author Service Manager my responsibilities include monitoring and facilitating all publishing activities for authors and editors. From chapter submission and review, to approval and revision, copyediting and design, until final publication, I work closely with authors and editors to ensure a simple and easy publishing process. I maintain constant and effective communication with authors, editors and reviewers, which allows for a level of personal support that enables contributors to fully commit and concentrate on the chapters they are writing, editing, or reviewing. I assist authors in the preparation of their full chapter submissions and track important deadlines and ensure they are met. I help to coordinate internal processes such as linguistic review, and monitor the technical aspects of the process. As an ASM I am also involved in the acquisition of editors. Whether that be identifying an exceptional author and proposing an editorship collaboration, or contacting researchers who would like the opportunity to work with IntechOpen, I establish and help manage author and editor acquisition and contact.
