Food and Nutrition is an essential topic in Biology – General Science that focuses on the nutritional requirements of the human body and the role of balanced diet in maintaining health. This chapter is frequently asked in competitive exams and government job exams to evaluate awareness of basic health and biological concepts.

Key areas include macronutrients such as carbohydrates, proteins, and fats, and micronutrients like vitamins and minerals. Topics such as balanced diet, caloric value of food, deficiency diseases (like anemia, rickets, scurvy), malnutrition, and functions of nutrients are commonly covered in exams. Understanding how proper nutrition supports growth, immunity, and energy production is vital.

Regular practice with MCQs, online mock tests, topic-wise quizzes, and previous year questions helps improve conceptual clarity, memory retention, and accuracy. A strong command of Food and Nutrition significantly enhances performance in competitive exams and government job exams such as SSC, Railway, Banking, UPSC, WBCS, State PSC, and other national and state-level recruitment examinations.
