MCQ Detailed View

Nutrients are chemical substances found in food that are essential for the growth, development, energy production, and proper functioning of living organisms. Broadly, nutrients are classified into two main types based on the quantity required by the body: macronutrients and micronutrients. Hence, the correct answer is 2 types of nutrients.

1️⃣ Macronutrients:

• 
  

  These are nutrients needed by the body in large amounts to provide energy and support overall physiological functions.

  
  


• 
  

  Major macronutrients include:

  
  
  
  
  • 
    

    Carbohydrates: Primary energy source for cells.

    
    
  
  
  • 
    

    Proteins: Important for growth, tissue repair, enzymes, and hormones.

    
    
  
  
  • 
    

    Fats (Lipids): Energy storage, insulation, and cell membrane formation.

    
    
  
  
  • 
    

    Water: Essential for digestion, transport of nutrients, and maintaining body temperature.

    
    
  
  
  
  


• 
  

  Macronutrients provide calories or energy, except water, which is vital for metabolic reactions.

  
  

2️⃣ Micronutrients:

• 
  

  Needed in small amounts but are crucial for proper metabolism, immunity, and disease prevention.

  
  


• 
  

  Include:

  
  
  
  
  • 
    

    Vitamins: Organic compounds like Vitamin A, B-complex, C, D, E, and K that regulate body processes.

    
    
  
  
  • 
    

    Minerals: Inorganic elements like calcium, iron, potassium, and zinc required for strong bones, blood formation, and nerve function.

    
    
  
  
  
  


• 
  

  Micronutrients do not provide energy directly but are necessary for utilizing macronutrients effectively.

  
  

Although food also contains fiber and antioxidants, they are not classified as main nutrient types but rather as dietary components aiding digestion and health.Thus, nutrients are broadly categorized into two types: macronutrients and micronutrients, making Option B (2) the correct choice. Both are equally important for maintaining a balanced diet and healthy living.
