Question

Quizplus · Accepted Answer

Iron deficiency is the most common nutrient deficiency worldwide, affecting approximately one-third of the global population. Iron is necessary for the production of hemoglobin, a protein in red blood cells that carries oxygen throughout the body. Iron deficiency can lead to anemia, fatigue, weakened immune system, and impaired cognitive function. Zinc and selenium deficiencies are also common globally, but not as prevalent as iron deficiency. Iodine deficiency is less common due to the widespread use of iodized salt, and magnesium deficiency is more common in specific populations, such as older adults and those with certain medical conditions.
