The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

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.
