Consider statements about human nutrition: 1. A balanced diet contains all essential nutrients. 2. Malnutrition can be caused by overeating. 3. Water is not a nutrient. Which are correct?
A. 1, 2 and 3
B. 1 and 2 only
C. 2 and 3 only
D. 1 and 3 only
Answer: Option B
Solution (By JKExamLibrary)
A balanced diet provides all the essential nutrients (carbohydrates, proteins, fats, vitamins, minerals, and water) in the correct proportions required for optimal health and growth. Malnutrition refers to deficiencies, excesses, or imbalances in a person's intake of energy and/or nutrients; therefore, overeating (leading to obesity) is a form of malnutrition. Water is an essential nutrient, crucial for hydration, transport, and chemical reactions, though it provides no calories. Thus, statements 1 and 2 are correct.
