A nutrient is a chemical than an organism needs to live and grow or a substance used in an organism’s metabolism which must be taken in from its environment. Nutrients are the substances that enrich the body. They build and repair tissues, give heat and energy, and regulate  body processes. Methods for nutrient intake vary, with animals and protests consuming foods that are digested by an internal digestive system, but most plants ingest nutrients directly form the soil through their roots or from the atmosphere. The effects of nutrients include carbohydrates, fats, proteins (or their building blocks, amino acids), and vitamins. Inorganic chemical compounds such as dietary minerals, water, and oxygen may also be considered nutrients. A nutrient is essential to an organism if it cannot be synthesized by the organism in sufficient quantities ad must be obtained form an external source. Nutrients needed in large quantities are called macronutrients, micronutrients are required in only small quantities. A human body needs lot of nutrients to keep it fit and healthy. All these aspects of nutrients have been explained in this book in a very simple and lucid manner. It is hoped that this book will be useful not only to dietician but also to common reader.
