This book summarizes key information required for planning and implementing a healthy diet for patients based on sound nutritional concepts. Readers will find information on the background of nutrition in disease management and nutritional regulations in the USA. The book also describes macro- and micronutrients (including minerals and vitamins) and the applications of relevant nutritional concepts to real-life situations, using well-designed simulated clinical scenarios. Additionally, factors contributing to disease as well as the link between socio-economic status, culture and nutrition are discussed. This book should serve as a useful handbook for nutritionists and health care providers and medical or pharmacology students taking courses in nutritional sciences.
