Dietary fructose, when compared to cornstarch, exacerbates copper deficiency. The purpose of this study was to determine whether Zn deficiency is similarly enhanced by high fructose intake. Seventy-five male SD rats were randomly assigned to one of the following diets containing 62% of the indicated carbohydrate: Zn deficient (0.6 ppm) X fructose; Zn deficient X starch; Zn supplemented (32 ppm) X fructose; Zn supplemented X starch. Animals were pair-fed to the Zn deficient X fructose group for 4 weeks. Survival, weight gain and tissue weight were also affected by dietary Zn, but not dietary carbohydrate. Dietary carbohydrate also failed to alter food intake of rats consuming Zn deficient diets. Unlike copper deficiency, the severity of Zn deficiency is not increased by feeding diets high in fructose compared to starch. The lack of a carbohydrate effect on zinc status indicates that the fructose-copper interaction is selective. This knowledge will facilitate the design of studies aimed at defining the mechanism(s) underlying fructose-trace element interaction.
