This study compared the effects of beef and breakfast cereals on zinc absorption. The study included eight healthy adults who were given foods containing approximately 4 mg (61.2 mumol) zinc as either beef or a high-fiber, ready-to-eat breakfast cereal.
The study revealed that zinc absorption from the high-fiber breakfast cereal was 14.7%, whereas zinc absorption from beef was 55.1%.
The study demonstrates that zinc bioavailability from beef is about fourfold greater than from a high-fiber breakfast cereal.
