Nutrition is broadly defined as the complex interactions of humans with food. Choose the correct options with respect to the statement – A. Vitamins & minerals are called macronutrients B. It involves not only biochemical processes but also social processes C. It also involves economic and physiological factors D. Carbohydrates, proteins, lipids and water are known as micronutrient

Correct option is C

The correct answer is (C) B and C only

Explanation:
• Statement B is correct: Nutrition is a multidisciplinary field. It involves biochemical interactions (how cells use nutrients) and social processes (cultural food habits and social determinants of health).
• Statement C is correct: Economic factors (affordability of food) and physiological factors (digestion, absorption, and health status) are central to the definition of nutrition.
• Statement A is incorrect: Vitamins and minerals are micronutrients, as they are required in small quantities.
• Statement D is incorrect: Carbohydrates, proteins, and lipids are macronutrients, required in large quantities.

Information Booster:
• Macronutrients provide the energy (calories) necessary for body functions, while micronutrients are essential for biochemical reactions and metabolic health.
• Water is often categorized as a macronutrient because it is required in large amounts, though it does not provide energy.

Additional Knowledge:
• Bioavailability refers to the proportion of a nutrient that is absorbed and utilized by the body after ingestion.
• Malnutrition includes both undernutrition (deficiencies) and overnutrition (obesity).
