Vitamins and Minerals: Fact Versus Fiction, Hardcover/Myrna Goldstein

Descriere

Everyone knows that vitamins and minerals are nonnegotiable components of optimal health. But what exactly do these substances do in the body, and how much of each is needed? What happens if an individual ingests too little or too much of a particular vitamin or mineral? Which foods are the best sources of them, and are dietary supplements a safe alternative? Do certain vitamins and minerals offer protection against certain diseases and medical conditions?Vitamins and Minerals: Fact versus Fiction provides answers to these and many other questions in an accessible format, backed by summaries of key research findings. This book cuts through the confusion and hype that surround the nutrition and supplements industries to offer readers clear guidance founded on solid medical research. A standardized chapter structure and several appendices make the most important information readily available, while introductory essays explore fundamental topics--such as different types of intake recommendations and how they're determined--in greater depth.
