Foreign Substances and Nutrition

Foreign Substances and Nutrition - R. Tarjan

Foreign Substances and Nutrition (1980) is a concise, research‑oriented examination of how various external chemical agents—such as additives, contaminants, environmental pollutants, and residues introduced through industrial processing—interact with human nutrition and influence overall health. The book brings together scientific perspectives on the ways these foreign substances enter the food chain, how they are metabolized by the body, and what risks or physiological changes they may produce, emphasizing the growing concern of the late twentieth century about the safety of modern diets. It discusses the balance between technological progress in food production and the unintended consequences of exposing consumers to synthetic compounds, highlighting both regulatory challenges and gaps in scientific knowledge. Throughout, the authors stress the importance of understanding not only the toxicological effects of these substances but also their potential to interfere with nutrient absorption, metabolic pathways, and long‑term well‑being, making the book a thoughtful contribution to early discussions about food safety, public health, and responsible nutrition science.
