Second generation principal investigator of the Zutphen Study
Daan Kromhout (1950) retooled the nutritional studies of the Seven Countries Study when he was named Principal Investigator of the Zutphen Study by the Dutch authorities in 1978. He assumed together with Alessandro Menotti the central direction of follow up and data analysis of the Seven Countries Study following publication by Keys and colleagues of the ten-year study monograph in 1980.
In 1985 he initiated the Zutphen Elderly Study in which the traditional cardiovascular survey was extended as a prospective study of healthy ageing. Together with Aulikki Nissinen and Alessandro Menotti he coordinated the Finland, Italy, Netherlands, Elderly (FINE) Study. He became in 2001 the project leader of the HALE (Healthy Ageing Longitudinal study in Europe) project.
The Zutphen Study dietary surveys were unique for the Seven Countries Study as the diet was seven times investigated from baseline to 40 years follow-up. In 1985 the Zutphen Study showed an association of a small amount of fish consumption with a low rate of fatal coronary heart disease. In the period 1993-2006 the intake of flavonoids, especially flavanols, present in tea and cocoa, was associated with a lower risk of fatal cardiovascular events. These results formed the basis for randomized controlled dietary trials on omega-3 fatty acids and flavonoids especially flavanols.
The Zutphen Study hosted two major conferences of the principal investigators on Seven Countries Study findings in 1990 and 2002. Read more about the Dutch cohort in Zutphen.
