Martijn Bernard Katan (born 1946) is a Dutch nutritionist, an emeritus professor at the Vrije Universiteit Amsterdam and author of two popular science books on nutrition.
Katan was born in Arnhem in 1946.[1] He studied chemistry and biochemistry at the University of Amsterdam. He obtained his PhD in molecular biology in 1977 under Piet Borst from the same university.[1] Katan started working at Wageningen University in 1976 where he researched "Nutrition and risk factors for cardiovascular disease". In 1998, he was appointed professor of human nutrition at the university.[1] He was also the "Nutrition Foundation Professor" at the University of Nijmegen from 1985 to 1998. Between 1998 and 2003 he was scientific director of the Nutrition and Health program of the Wageningen Centre for Food Sciences.
In 2003 Katan became a member of the Royal Netherlands Academy of Arts and Sciences.[2] In 2005 he moved from Wageningen University to the Vrije Universiteit Amsterdam where he was appointed professor of nutrition.[1] Katan is a member of the Dutch Health Council.
He took up emeritus status in 2011.[3]
Katan's research focuses on the relationship between nutrients and their effects on the heart. Katan gained notoriety for his research on cholesterol and trans-fats.[1] He demonstrated, among other things, that boiled coffee creates a cholesterol burden that filtered coffee does not. His research on the harmful effects of trans-fatty acids has encouraged the food industry to minimize the use of trans-fats in the food supply.[4]
