MCQ Detailed View

Zinc is a vital trace mineral required by the human body for numerous biological processes, including cell growth, tissue repair, immune function, and metabolism. A deficiency of zinc can lead to several health problems, most notably loss of appetite and poor physical growth, particularly in children.

Zinc plays a key role in activating enzymes responsible for digestive function and taste perception. When the body lacks sufficient zinc, it disrupts these processes, leading to reduced sense of taste and smell, decreased desire to eat, and overall loss of appetite. Over time, inadequate food intake slows down body development and growth rate, which is especially harmful during childhood and adolescence when the body’s nutritional needs are high.

This mineral also contributes to protein synthesis, wound healing, reproductive health, and strengthening the immune system. Deficiency may cause additional symptoms like hair loss, delayed wound healing, weakened immunity, skin problems, and stunted growth.

Zinc is found naturally in many foods, including meat, poultry, seafood (especially oysters), beans, nuts, seeds, and whole grains. Regular intake through a balanced diet prevents deficiency. Pregnant women, infants, and people with digestive disorders are at a higher risk of zinc deficiency and may require supplements under medical advice.

Other minerals listed in the options—iodine, copper, and iron—are also essential for good health, but they are linked to different conditions. Iodine deficiency affects thyroid function, copper deficiency can impact blood and nerve health, and iron deficiency mainly causes anemia. Only zinc deficiency is strongly associated with loss of appetite and impaired growth.

Understanding the role of zinc helps in recognizing how micronutrient imbalances can affect overall health and development, making it an important topic in Biology and human nutrition studies.
