Nutritional Science Basics: Macronutrients, Micronutrients, and Metabolism

This book provides a structured introduction to the fundamentals of nutritional science. It addresses the complex interplay of macronutrients, micronutrients, and human metabolism. Readers will gain a comprehensive understanding of how carbohydrates, proteins, and fats are processed in the body to provide energy, build structures, and perform vital functions.The content systematically explores the role of vitamins and minerals, with a focus on their bioavailability and the factors influencing their absorption. Key topics include the calculation of energy balance through an examination of basal metabolic rate, the thermic effect of food, and energy expenditure from physical activity. This allows for a deeper insight into individual nutrient requirements.A significant section is dedicated to applied food science, explaining how preparation and storage methods affect the nutrient density of foods. It also covers functional foods, phytochemicals, and dietary fiber, clarifying their contributions to health. Furthermore, the book introduces the growing field of the gut microbiome, detailing how diet influences its composition and its subsequent impact on the immune system and overall well-being.Practical guidance on dietary assessment is provided, including methods for analyzing personal nutrient intake and recognizing potential deficiencies. The principles of evidence-based nutrition are a central theme, empowering readers to critically evaluate nutritional information and differentiate between correlation and causation in scientific studies. The book is designed for anyone seeking a solid foundation in nutrition, based on scientific principles of metabolism and food science.For this book, we have used modern technologies – including Artificial Intelligence and individually developed software solutions.
