## Preface

Human intestinal tract is colonised by several thousand species of bacteria. They represent both the beneficial bacteria as well as harmful ones. Beneficial bacteria are referred to as 'pro‐ biotics'. Predominance of probiotic bacteria is considered essential for the prevention of hu‐ man diseases and maintenance of good health. Prebiotics are non-digestible food ingredients that selectively promote the growth of probiotics in the gastrointestinal tract. More recently, the concept of 'synbiotic' relationship between the probiotics and prebiotics is being used as an effective strategy to maintain the predominance of the probiotics in the gastrointestinal tract. Research over the years and more recent research have shown the beneficial effect of probiotics in the prevention and management of several human diseases including cancer, cardiovascular diseases, gastrointestinal disorders, osteoporosis and neurodegenerative dis‐ eases. The recent focus of research is to identify the specific species of probiotics, types of prebiotics, their interactions and mechanisms of action in providing health benefits. Recogni‐ tion of the health benefits of probiotics and prebiotics has led to the marketing of several sup‐ plements. Government agencies are actively developing regulatory guidelines for the safety and efficacy of such supplements. In recognition of the importance of probiotics and prebiot‐ ics, the contents of the book include all the major concepts from their identification to clinical trials. The book has been carefully reviewed to include chapters that are relevant and repre‐ sentative of current research. We are confident that the readers of this book published by In‐ Tech publication that include researchers, health professionals, government regulatory agencies and industries will find it highly useful as a standard reference book.
