Staying Healthy with Nutrition, Rev by Elson M. Haas and Buck Levin Review: An Encyclopedic Reference for Serious Nutrition Seekers

A revised, encyclopedic guide to diet and nutrition co-authored by integrative medicine physician Dr. Elson M. Haas and Dr. Buck Levin, this 944-page reference compiles decades of clinical experience and scientific research into a structured, four-part volume covering nutritional building blocks, food and diet evaluation, environmental health, and lifestage-specific programs — earning an endorsement from Andrew Weil, M.D. as "an excellent guide for those wishing to make smarter dietary choices."

LuvemBooks Verdict

Best for

Readers who want a serious, structured single-volume nutrition reference — from general readers building nutritional literacy to students of dietetics or integrative medicine seeking a consolidated clinical foundation.

Worth it if

Worth it if you want one authoritative, encyclopedic nutrition reference on the shelf that covers macronutrients, global dietary approaches, environmental health, and lifestage-specific protocols in depth, written by credentialed integrative medicine practitioners.

Skip if

Skip it if you're looking for a concise, prescriptive diet plan or need cutting-edge guidance on rapidly evolving topics like specific supplement research or mood-disorder protocols, as the 2006 publication date means some areas will require cross-referencing with more recent science.

What readers & critics say

Publisher and retailer listings retrieved from Penguin Random House and ThriftBooks describe the revised edition as an encyclopedic volume compiling decades of practical experience and scientific research, presented in an easy-to-use format with a friendly, engaging tone. The author's own site (elsonhaasmd.com) characterises it as "an improved and expansive look at nutrition and health" drawn from Haas and Levin's combined clinical findings.

What Works & What Doesn't

What Works
  • Encyclopedic in scope, covering nutritional building blocks, global food and diet evaluation, environmental health factors, and lifestage-specific programs in one structured volume
  • Co-authored by credentialed practitioners — Dr. Haas brings 40 years of integrative family medicine experience and ten published books on nutrition and health
  • Revised edition features newly expanded chapters on special supplements, lifestage programs, and treatment protocols for conditions including anxiety, ADHD, depression, fatigue, and weight management
  • Endorsed by Andrew Weil, M.D., who calls it 'an excellent guide for those wishing to make smarter dietary choices'
  • Four-part organizational structure is designed for accessibility, allowing readers to navigate a nearly 1,000-page reference without reading it cover to cover
What Doesn't
  • At 944 pages, the encyclopedic format is not suited to readers seeking a concise, prescriptive diet plan
  • Published in 2006, some rapidly evolving topics — such as specific supplement research, environmental chemical guidelines, and mood-disorder protocols — will have been updated by subsequent science, requiring readers to cross-reference current sources
A landmark of integrative nutrition literature, this revised edition remains one of the most comprehensive single-volume references available to general readers and health professionals alike.

What the Book Is and What It Covers

Staying Healthy with Nutrition, rev: The Complete Guide to Diet and Nutritional Medicine by Elson M. Haas, Buck Levin front cover
Staying Healthy with Nutrition, rev: The Complete Guide to Diet and Nutritional Medicine by Elson M. Haas, Buck Levin front cover
Staying Healthy with Nutrition, Rev: The Complete Guide to Diet is a reference guide — not a memoir, cookbook, or narrative — authored by Dr. Elson M. Haas, an integrative family medicine practitioner and founder of the Preventive Medical Center of Marin in San Rafael, California, and Dr. Buck Levin. Together they draw on decades of practical clinical experience and scientific research. The book is organized into four major parts. Part One delivers a detailed analysis of nutrition's foundational building blocks: water, carbohydrates, proteins, fats and oils, vitamins, minerals, and other nutrients. Part Two evaluates food groups and diets, ranging across most dietary approaches found around the world. A dedicated chapter on the environment and nutrition addresses food additives, industrial chemicals, food irradiation, and electro-pollution. Part Four provides lifestage-specific programs and nutritional protocols. This architectural clarity gives readers a logical path through an otherwise vast subject.

Scope, Depth, and the Revised Edition's Expansions

What distinguishes this revised edition from its predecessor is a set of newly expanded chapters. The book adds coverage of special supplements, lifestage programs, and what the publisher describes as breakthrough medical treatment protocols for fatigue, viruses, weight management, and mental and mood disorders — including anxiety, ADHD, and depression. These additions reflect shifts in both clinical practice and public health concern since the original edition. The result is an encyclopedic volume that, as Penguin Random House's description notes, is designed to present authoritative health and nutrition information in an easy-to-use format and a friendly, engaging tone. Andrew Weil, M.D., author of Healthy Aging, calls it "an excellent guide for those wishing to make smarter dietary choices" — a notable endorsement given Weil's own standing in integrative medicine.

Credentials and Authority Behind the Content

The credibility of the content rests substantially on its authors' professional backgrounds. Dr. Haas is described by his publisher as an integrative family medicine practitioner with 40 years of healthcare experience and the author of ten books on health, nutrition, and detoxification, including Staying Healthy with the Seasons, The Detox Diet, and The False Fat Diet. Dr. Buck Levin's contributions bring additional research depth to the collaboration. This is not a general-interest wellness title assembled by a generalist writer — it is a clinical reference shaped by practitioners who have applied these principles in patient care. Readers who want a volume grounded in professional medical and nutritional science, rather than popular diet trends alone, will find that pedigree meaningful.

Limitations and Considerations for the Reader

The very comprehensiveness that makes this book valuable also defines its primary limitation: at 944 pages, it is a substantial commitment, and readers seeking a quick, prescriptive diet plan will find the format more demanding than a streamlined popular health title. The revised edition was published in 2006 by Celestial Arts, which means that while the foundational science of macronutrients and micronutrients remains durable, some of the specific protocols — particularly those addressing emerging research on supplements, environmental chemicals, or mood disorders — will have been superseded by nearly two decades of subsequent research. Readers relying on it for up-to-the-minute clinical guidance on rapidly evolving topics should cross-reference with more recent sources. This is a structural reality of any encyclopedic reference of this scale, not a flaw unique to this title, but it is worth weighing.

Who This Book Is Genuinely For

Staying Healthy with Nutrition, Rev is designed for readers who want a serious, structured, and thorough reference rather than a trend-driven diet book. Its four-part architecture makes it navigable for general readers building nutritional literacy from the ground up, while its depth and clinical framing also suit students of nutrition, dietetics, or integrative medicine who want a consolidated foundational resource. Readers who appreciate Dr. Haas's other titles — or who come to this book through an interest in integrative and preventive medicine — will find his collaborative work with Dr. Levin to be among the most thorough expressions of that perspective available in a single volume. For households that want one authoritative nutrition reference on the shelf, this revised edition has served that role for many readers.
