An Epidemic of Absence

An Epidemic of Absence investigates the connection between the modern world's hyper-sanitized conditions and the rise of allergies, autoimmune disorders, and inflammatory diseases. The author chronicles his personal journey with autoimmunity while exploring research into the "hygiene hypothesis" and its implications for human health. The book examines how the elimination of parasites, bacteria, and other microorganisms from developed societies may have disrupted the human immune system's natural development. Through interviews with scientists and patients, Velasquez-Manoff documents unconventional treatments involving controlled exposure to parasites and microbes. The narrative spans multiple continents and centuries, tracing humanity's evolving relationship with microscopic organisms and the impact of industrialization on our immune systems. This work presents a complex scientific story about the price of progress and the potential need to recalibrate our relationship with the microbial world.

Readers note the book provides detailed scientific explanations about how modern hygiene may contribute to autoimmune disorders, citing extensive research into parasites, bacteria, and immune system function. Readers appreciated: - Clear explanations of complex immunology concepts - Personal stories and case studies - Thorough research citations - Balanced presentation of evidence Common criticisms: - Repetitive content and examples - Overly long at 400+ pages - Technical language can be dense - Some readers wanted more practical recommendations Review Scores: Goodreads: 4.1/5 (1,100+ ratings) Amazon: 4.5/5 (200+ ratings) Sample reader comments: "Fascinating science writing that connects dots between modern diseases and our sanitized lives" -Goodreads reviewer "Could have been condensed significantly without losing impact" -Amazon reviewer "Changed how I think about bacteria and health, but needed better editing" -LibraryThing reviewer The science journalism and research synthesis earned praise while length and organization drew criticism.

The Wild Life of Our Bodies by Rob Dunn The book explores how human health connects to our evolutionary history with parasites, predators, and microbes.

I Contain Multitudes by Ed Yong The text examines the microbiome's role in human health and its influence on disease, behavior, and evolution.

Missing Microbes by Martin J. Blaser A research-based investigation into how modern practices have disrupted the human microbiome and its impact on disease patterns.

The Good Gut by Justin Sonnenburg, Erica Sonnenburg The book connects microbiome research to human immune function, metabolism, and disease prevention through scientific evidence.

10% Human by Alanna Collen The work presents research on how microbes shape human development, immunity, and chronic disease patterns in modern society.

🦠 Velasquez-Manoff underwent experimental helminth therapy himself while researching this book, deliberately infecting himself with hookworms to test the hygiene hypothesis firsthand. 🔬 The book explores how the eradication of parasitic worms may have contributed to the rise of autoimmune disorders in developed countries, particularly in urban areas. 🌍 Traditional societies with high parasite loads tend to have dramatically lower rates of allergies, autoimmune disorders, and certain inflammatory conditions. 🧬 The author's personal connection to the subject stems from his own autoimmune conditions, including alopecia universalis, which causes complete hair loss. 🔄 The "Old Friends" theory discussed in the book suggests that humans co-evolved with certain microorganisms over millions of years, and their absence in modern life may be disrupting our immune system development.
