The book begins by differentiating between essential metals like iron and toxic ones like lead, then traces their journey from the earth to our food. It investigates agricultural practices such as pesticide use, industrial pollution's effect on soil, and metal leaching during food processing. By drawing on diverse sources, including environmental data and toxicology research, the book adopts a holistic approach, considering the entire food chain from soil to plate.
The book progresses across chapters by first establishing a baseline understanding of trace metals, then discussing the geochemical cycles of these metals, tracing their movement from the earth's crust to the atmosphere, water sources, and ultimately, agricultural lands. Later chapters investigate the primary routes of metal contamination in food.
This book empowers readers to make informed choices regarding food safety, supporting policies for food safety and advocating for sustainable agricultural practices.
