ABSTRACT
Chromium (Cr) has been used as a tool for diagnosis and research in hematology, as a label for red blood cells and as a fecal marker. Foods such as mushrooms, nuts, whole grains and processed meats, as well as wine and beer, are good sources of Cr. Foods high in simple sugars such as fructose are low in Cr content and actually promote Cr losses. The results of the G. W. Evans studies have been challenged using more stringent supplementation protocols and sensitive measures of body composition. The overwhelming majority of the well controlled research studies estimate that no additional Cr is needed for adults consuming a balanced diet and that caution should be used with taking over-the-counter supplements because of potential for serious side effects. The use of supplemental Cr appears to have no effect on measures of physical performance when used in association with an exercise program.
