Excessive consumption of cobalt can lead to an overproduction of red blood cells, increased blood volume and anemia.

It is the total diet or overall eating pattern that is most important in disease prevention and achieving good health. It is better to eat a diet with a variety than to concentrate on individual nutrients as the key to good health.
