Special | 59m 1sVideo has Closed Captions
Roger A. Sunde explains the discovery of essential minerals during research for vitamins.
Roger A. Sunde, Professor, Department of Nutritional Sciences, UW-Madison, explains that copper and zinc, essential elements, were discovered in food while using the bioassay approach (feeding studies with rats) while searching for vitamins. Both vitamins and trace essential minerals were present in levels so low as to evade detection by analytical means, and had to be teased out using bioassay.
