This edition reflects the increasing importance of nutritional care in the health sector, particularly in the context of growing lifestyle diseases, rising nutritional deficiencies, and the shifting burden of disease in India and globally. Nurses are often the first point of contact in both preventive and curative healthcare, and their role in nutritional counseling, diet planning, and patient education is critical. With this in mind, the content of this book has been carefully curated to cover a broad range of topics, including macronutrients and micronutrients, their dietary sources, functions, and deficiency symptoms. It also discusses Recommended Dietary Allowances (RDA), balanced diets, food safety, meal planning, and the dietary management of common health disorders.
