There has been a corre¬ sponding shift in preferences of these modem consumers to seek natural and gentler alematives to prescription drugs or standard, over-the-counter medications. These circumstances have created an unprecedented need for the education of consumers in the appropriate use of an increasing number of popular dietary supplements. The work of Nicola Reavley fills that need by providing reliable, credible information on the health benefits and limi¬ tations of dietary supplements. The result is a definitive guide to dietary supplement use. If one paces the aisles of any bookstore, the vast array of popular books on nutritional and “natural” options for health becomes immediately appar¬ ent. Sampling some of these books, even at a glance, raises issues about the validity of the recommendations or material contained within the books. There seems to be an ever increasing number of self-proclaimed experts in alternative and complementary medicine who expect their ideas to be ac¬ cepted without reference to peer-reviewed literature. A common thread of wishful, mythical, or magical concepts emerges in some books that offer the latest “cures,” using vitamins, botanicals, or herbs. This book provides an antidote, by presenting information in a logical and credible manner, carefully referenced. The New Encyclopedia of Vitamins, Minerals, Supplements, and Herbs undertakes a thorough analysis of recent and exciting trends in the applica¬ tion of nutritional principles in disease-prevention management with nutriceuticals. It helps dispel many of the myths that are propagated by the zealous sectors of the dietary supplement industry who may ply their wares on tenuous grounds. Nicola Reavley has produced a book that is a must for any consumer who seeks a valid reference to the application of dietary supplements for health benefits. It presents appropriate cautions in some circumstances and reinforces the important notion that just because something is natural does not necessarily mean that it is safe. This work is also a blessing for health food store and retail pharmacy staff and their clients, who are faced with difficult decisions in choosing the right supplement or popular natural health option. My colleagues in clinical practice who have a need to address their patients’ needs for information on supplement use will find this book in¬ valuable. Even the most hidebound practitioner of conventional medicine would not shun this author’s logical and well-referenced work. VIII FOREWORD Nicola Reavley has written a highly relevant, accurate, and up-to-date definitive guide on the appropriate and judicious use of dietary supplements. Please enjoy this book in health—it has a lot to offer. —Stephen Holt, M.D., FRCP (C), FACP, FACN, FACG, MRCP (UK) Author of The Soy Revolution and The Natural Way to a Healthy Heart President, Illinois College of Physicians and Surgeons
