I am a nutritionist and epidemiologist, working as postdoctoral researcher at the department of Epidemiology of Erasmus MC University Medical Center. My research focuses on the role of nutrition in health throughout the life course, with a particular emphasis on nutrition in early life and on obesity and cardiometabolic health. For my studies I use data from the population-based cohorts the Rotterdam Study (n~15,000 elderly) and the Generation R Study (n~10,000 women and their children), and I perform several systematic reviews and meta-analysis. My research interests include dietary patterns analysis, macronutrient substitution models, fatty acids and fatty acid patterns, effects of diet and lifestyle on insulin sensitivity and the development of diabetes, body composition (lean, fat and bone mass), blood lipids, vitamin D, epigenetics as potential intermediate between nutrition and health, gene-diet interactions, and maternal and infant nutrition. I have so far published 32 international scientific papers and 1 book chapter and currently lead a research line including 5 PhD students and 6 Master students.

Contributions to Science
1. The importance of nutrition in early childhood for health. In several publications, I found that dietary factors in early childhood were associated with later growth, body composition and cardiometabolic health. For this research, I used several approaches to study diet, including macronutrient substitution models to examine macronutrient composition of the diet and dietary pattern analyses to define diet quality and derive dietary patterns best predicting a certain health factor. For example, I found that a high protein intake in early childhood is associated not only with a higher BMI, but specifically with a higher body fat mass, and that dietary patterns at an age as early as 1 year can predict later body composition.

2. The high prevalence of vitamin D deficiency and its determinants and consequences. I found that almost one-third of 6-year-old children in Rotterdam were vitamin D deficient, with 6% being severely vitamin D deficient. Of children with a non-Dutch ethnic background, more than half had vitamin D deficiency. Other important determinants were related to lifestyle (playing outside, diet quality, watching television) and family sociodemographic factors such as family income. Also among elderly in Rotterdam, vitamin D deficiency is highly prevalent, with 57% having vitamin D deficiency. Vitamin D deficient subjects were found to be at higher risk of obesity, myopia, and dyslipidemia.
