La dosis hace el veneno: una guía de toxicología en lenguaje sencillo

What is this book about?

In a world where headlines about dangerous chemicals and food additives are constant, The Dose Makes the Poison: A Plain-Language Guide to Toxicology becomes an essential tool. This book demystifies toxicology, the science that studies the effects of chemical substances on living organisms. Its fundamental premise, coined by Paracelsus, is that the dose makes the poison. That is, any substance can be toxic depending on the quantity, the route of exposure, and the duration. Throughout its pages, the authors explain concepts such as the dose-response relationship, the difference between real and perceived risks, and how we assess the safety of the products we use daily. The book is not only a guide to understanding alarming headlines but also a practical manual for making informed decisions about our health and the environment.

Who is this book for?

This book is aimed at anyone who wants to better understand chemical risks in their daily lives. It is especially useful for:

• Consumers interested in the safety of food additives and household products.
• Health science, nutrition, or environmental students looking for a clear introduction to toxicology.
• Journalists and communicators who need to unravel complex scientific reports.
• Professionals in the food or pharmaceutical industry who wish to update their knowledge.

No prior knowledge of chemistry is required; the language is accessible, and concepts are explained from scratch.

What does this book include?

The work covers everything from the fundamentals of basic chemistry to risk assessment. Its contents include:

• Clear explanations of how chemicals enter the body and how they are metabolized.
• Differences between natural and synthetic compounds, and why natural is not always safe.
• Real cases of poisoning and lessons learned.
• A review of the main regulatory agencies and their safety criteria.
• Tables and graphs that facilitate the understanding of dose-response curves.

In addition, the book is logically structured, with chapters that progress from basic to applied concepts, and a glossary of key terms.

About the Authors

Patricia Frank and M. Alice Ottoboni are the authors of this work. Both have extensive experience in the field of toxicology and science communication. Their goal in writing this book was to make a discipline often perceived as complex accessible, offering a reliable resource for the general public. The combination of their technical expertise and their ability to explain difficult concepts simply makes this guide a unique reference.

Frequently asked questions about toxicology

What does "the dose makes the poison" mean?

It is the fundamental principle of toxicology: any substance can be toxic if the exposure is sufficiently high. Even water can be lethal in large quantities. The important thing is the relationship between quantity and effect.

Are all food additives dangerous?

No. Additives authorized in the European Union have undergone rigorous safety evaluations. The book explains how safe doses are determined and why some additives generate controversy.

Hazard is the intrinsic capacity of a substance to cause harm; risk is the probability that such harm will occur under actual conditions of use. The book clarifies this common confusion.

The authors teach how to critically read scientific reports, identifying biases and understanding the limitations of animal or in vitro studies.
