What affect will the mineral chromium have on insulin and glucose in a person with diabetes?

According to the Nutritional Recommendations and Principles for People with Diabetes Mellitus of the American Diabetes Association (ADA), the only know circumstance in which chromium replacement has any beneficial effect on blood sugar is for people who are chromium deficient as a result of long-term chromium-deficient parenteral nutrition. However, it appears that most people with diabetes are not chromium deficient and, therefore, chromium supplementation has no known benefit at all either for insulin as well as for blood sugar. Therefore, chromium supplementation for people with diabetes mellitus is not recommended until further testing is completed. This is especially important given the potential for any unforeseen side effect.
