Dietetics & Nutrition in Healthcare presents a comprehensive and practice-oriented exploration of nutrition science as it applies to health promotion, disease prevention, and clinical care. The book is thoughtfully structured to guide readers from fundamental concepts of dietetics and nutrition to advanced applications in clinical and community settings. Beginning with an introduction to nutrition in healthcare, it builds a strong foundation through detailed discussions on sugars, nuts, oilseeds, bioactive compounds, and functional food components. Special emphasis is placed on product design in nutrition, including traditional formulations such as chyawanprash, highlighting the integration of scientific knowledge with cultural and practical relevance.The book further examines the composition, nutritive value, and quality aspects of commonly consumed foods such as milk and milk products, eggs, poultry, meat, and fish, along with changes that occur during processing and cooking. These chapters bridge basic food science with real-world dietary decision-making. The later sections introduce clinical nutrition and dietetics, supported by case studies that illustrate nutrition assessment, planning, and intervention across different health conditions and lifestyles.A distinctive feature of this book is its strong focus on experiential and applied learning. Practical experiments-including body fat measurement, metabolic rate assessment, glycemic index evaluation, lactate threshold testing, and VO₂ max estimation-equip learners with essential assessment skills used in modern nutrition practice. Exercises on balanced meal planning, product formulation, and supplement design, along with practice case studies on obesity and sedentary lifestyles, encourage critical thinking and personalized nutrition planning.Written with the intent to simplify complex concepts without compromising scientific rigor, this book serves as a valuable resource for students, educators, and healthcare professionals. By blending theory, practice, and culturally relevant examples, Dietetics & Nutrition in Healthcare aims not only to inform but also to inspire mindful, evidence-based, and individualized approaches to nutrition in academic study, clinical practice, and everyday life.
