Step 1: Understanding the Concept:
Hidden hunger refers to a form of malnutrition where people eat enough calories but don't get essential vitamins and minerals.
Step 2: Detailed Explanation:
Even if a person consumes enough energy (carbohydrates/fats), they can still be malnourished if their diet lacks micronutrients like Iron, Iodine, Zinc, and Vitamin A.
Because the person doesn't feel "hungry" in the traditional sense, the deficiency remains "hidden."
This leads to serious health consequences such as anemia, stunted growth, and weakened immune systems.
Step 3: Final Answer:
Micronutrient deficiency is the cause of hidden hunger.
