Chromium: an essential micronutrient.

A balanced, varied and "prudent" diet is likely to furnish the chromium requirement, whereas a high-fat, high-sugar, high-alcohol diet would not. A "prudent" diet will confer health benefits in addition to those derived form the adequacy of chromium intake, and it will obviate the need for supplementation with chromium compounds that are commercially available, but not scientifically proven to be effective. Chromium supplementation, other than by dietary means, should be used only when advised by and under the supervision of a physician.
