Iron is an essential mineral required for many bodily functions, most notably the synthesis of hemoglobin, the protein in red blood cells that carries oxygen.

– Deficiency of iron leads to decreased production of hemoglobin. This results in a condition called iron-deficiency anaemia, characterized by a reduced number of red blood cells or a reduced amount of hemoglobin in the blood, impairing oxygen transport. Symptoms include fatigue, weakness, and paleness.
– Scurvy is caused by Vitamin C deficiency.
– Rickets is caused by Vitamin D deficiency (leading to impaired calcium and phosphorus absorption).
– Cholera is an infectious disease caused by bacteria, not a nutrient deficiency.

Iron is also important for myoglobin (oxygen storage in muscles), enzyme function, and immune function. Dietary sources of iron include red meat, beans, lentils, and fortified cereals.
