• Short-term periods of strenuous physical activity lower iron absorption

    8 days ago - By American Journal of Clinical Nutrition

    In this issue of the American Journal of Clinical Nutrition, Hennigar and colleagues ( 1 ) report a meticulously designed and controlled investigation with the overall finding that strenuous physical activity decreases iron absorption compared to rest, as assessed using stable iron isotope appearance curves. In brief, 10 volunteer, healthy, active-duty military personnel completed a randomized, cross-over, controlled-feeding clinical trial involving two 72-h periods of simulated sustained military and training operations. These episodes of physical activity consisted of three ∼60- to...
