Most minerals from groundwater, including iron, will be absorbed by water. Large amounts of iron in drinking water can give it an unpleasant metallic taste. Iron is an essential element in human nutrition, and the health effects of iron in drinking water may include warding off fatigue and anemia.
Iron is an important mineral that is involved in various bodily functions, including the transport of oxygen in the blood. This is essential for providing energy for daily life. Good sources of iron include red meat, offal and iron-fortified breakfast cereals. Iron is lost from the body through sweat, shedding intestinal cells, and blood loss.
Iron Fe is a component of hemoglobin, myoglobin, and many enzymes in the body. Heme iron, contained mainly in animal products, is absorbed much better than nonheme iron eg, in plants and grains, which accounts for 85 of iron in the average diet. However, absorption of nonheme iron is increased when it is consumed with animal protein and vitamin C.
