title: Influence of dietary carbohydrate on copper, iron, and zinc status of the rat.
abstract: Rats were fed diets containing starch, sucrose, glucose, or fructose as the carbohydrate source, and the influence of these carbohydrates on copper, iron, and zinc status was determined. It was found that copper absorption was reduced in animals receiving glucose. This reduction was exaggerated when a high level of iron was present in the diet, indicating a possible antagonism between iron and copper at the site of absorption. Iron and zinc status of the animals also appeared to be influenced to some extent by dietary carbohydrate.
