Preface

Antioxidants have become a household name ever since their potency against many non-communicable diseases was demonstrated several decades ago. It is one of the most sought-after and active areas of research where the velocity of scientific discovery has remained at a steady increase. Not only among the scientific community, but even among consumers, the term "antioxidants" is a familiar matter. With an increasing number of consumers looking toward health and wellness, this group of biological compounds has gained much popularity, where incorporation of the word itself has been known to boost product sales.

The intention of this book is to provide an overview of antioxidants, their pathways of action, the mechanisms of antioxidant assays, and their potential sources. While most of these areas might appear mundane and therefore, already reviewed, it is without a doubt that the knowledge along these aspects keep getting renewed on a daily basis. There are several chapters of interest for readers who are from a nonscientific background, especially when it comes to identifying potent sources of antioxidants.

At the same time, almost all the contents of this book are positioned in the form of an update, where new discoveries and novel perspectives are provided. The authors contributing to this book span over various scientific backgrounds throughout several countries; therefore, the variety adds more color and value to its content.

I would like to take this opportunity to extend my appreciation to the authors who have contributed so many wonderful chapters to this book as well as my heartfelt appreciation to the IntechOpen Publisher with whom I have worked on several publications. Last, but not least, my appreciation goes to Mr. Josip Knapić - the Author Service Manager assigned to this book, who has rendered his fullest support in putting the material together.
