Undernutrition: This is when the body doesn't get enough nutrients. It's like trying to drive a car on an almost empty tank of gas.
Overnutrition: This happens when the intake of nutrients is oversupplied. It's like overfilling your car with gas until it spills out.
Micronutrient deficiency: This occurs when the body lacks necessary vitamins and minerals. It's like forgetting to change the oil in your car; everything might seem fine at first but eventually problems will arise.
