Implication

Animal bioassay reveals stable iron bioavailability across diets in animal models, suggesting the supplemental iron source governs absorption more than food processing.

Key Points

To evaluate whether the animal hemoglobin repletion test effectively measures iron bioavailability across various fortified food products.
Applied the animal hemoglobin repletion test to measure iron availability in multiple food products incorporated into animal test diets.
Maintained constant protein and energy levels in the basal diet when adding test food products with adequate native iron concentrations.
Iron bioavailability was qualitatively equivalent when the iron source was added directly to the diet versus when incorporated as a food ingredient.
The specific source of supplemental iron had a greater qualitative impact on bioavailability than other dietary components.
Thermal processing, including cooking farina or baking biscuits from enriched cereal, exerted little to no observable effect on iron bioavailability.
