What are deficiency symptoms for chromium?

Dietary deficiency of chromium is believed to be widespread in the United States, a consequence of food processing methods that remove most of the naturally occurring chromium from commonly consumed foods. Chromium deficiency leads to insulin resistance, a condition in which the cells of the body do not respond to the presence of insulin. Insulin resistance can lead to elevated blood levels of insulin (hyperinsulinemia) and elevated blood levels of glucose, which can ultimately cause heart disease and/or diabetes.
