The World Health Organization says iron deficiency is the most common nutritional disorder in the world.

Iron deficiency and anemia are especially common among children in developing countries. englishtang.com
The body needs iron to manufacture hemoglobin. Hemoglobin is the protein in red blood cells that carries oxygen to body tissues. The body also needs iron to produce several enzymes necessary for muscle, the brain and the body's defenses to work correctly.

A Canadian scientist, Doctor Stanley Zlotkin, says he has a solution. Iron and other minerals necessary for good health can be processed into very small particles.

He says the sprinkles come in the amount needed to meet a child's daily need for iron at a cost of three cents or less a day. There is also vitamin C,abercrombie, which helps the body process iron, and vitamin A, zinc, and folic acid. english tang .com
Sprinkles are already in limited use. Doctor Zlotkin says his goal is to expand the use of sprinkles in the nutrition policy of all developing countries. Earlier this year, Doctor Zlotkin and other scientists reported on successful tests in West Africa. The Public Library of Science published the findings.
