Final answer:
Chromium enhances the action of ceruloplasmin, which is important for the transport of copper and iron in the body. Deficiency can lead to diabetes-like symptoms or neurological problems. While whole grains are a good source of chromium, taking supplements may have negative health effects.
Step-by-step explanation:
In nutrition, chromium has several important characteristics. One of these is that it enhances the action of ceruloplasmin, which is a plasma protein involved in the transport of copper and iron in the body. This function is crucial for proper hemoglobin production and preventing anemia. Chromium deficiency can lead to diabetes-like symptoms or neurological problems, especially in the extremities. It is important to note that whole grains can represent a good source of chromium in the diet, but taking chromium supplements is not well-known to be helpful and can even lead to negative health effects.
