This book is dedicated to one of the most pressing topics of our time. Today, our diet includes more and more unnatural, synthetic products, some of which are hazardous to health. A competent buyer should be able to distinguish them. Which of the products that we eat every day did not appear in the natural environment, but were created in laboratories and chemical plants? What is the difference between natural mayonnaise and yoghurt and “improved long-livers” with the same name? Why is margarine unfamiliar to our digestive system? Are bouillon cubes healthy? You will find answers to all these and many other pressing questions in the book. The book is designed for the widest range of readers - regardless of age, gender and income level.
