Personal Statement

My research over the past 5 years consists of two pillars. The first pillar includes research on the role of nutrition along the life-course (i.e. during pregnancy, childhood and adulthood) and cardiometabolic and gastrointestinal diseases. Specifically, she studies dietary patterns since these are more informative than studying individual foods, because it reflects the real-life situation of a combination of foods that people eat instead of specific products that are rarely eaten in isolation. These projects are embedded in the Rotterdam Study, a population-based prospective cohort study among middle-aged and elderly, as well as in the Generation R Study, a population-based birth cohort. In 2014 and 2016, I visited the Harvard School of Public Health in Boston USA to study the diet-dependent acid load hypothesis. Also, I am involved in several international consortia on projects on diet and non-communicable diseases. Since 2014, I am expanding my research line with a second pillar closely related to the field of public health nutrition, related to the sustainability of diets from a psychosocial and environmental perspective. My team studies the environmental determinants and impact of dietary patterns and the extent of food insecurity in disadvantaged families in The Hague. Recently I received the Dekker fellowship of the Dutch Heart Foundation to study the concept of teachable moments towards dietary and lifestyle change. I have supervised more than 25 MSc students and 6 PhD students and I am currenty (co-)promotor of 5 PhD students. I have is (co-)authored more than 100 articles published in international peer-reviewed journals.

Contributions to Science

1. Supervision and mentorship:
Since 2012, I am a mentor and co-promotor of several PhD students focusing on research related to nutrition & health:
• Myrte Tielemans, Eating for two in pregnancy: health outcomes in pregnant women and their children (PhD-defense: 29-06-2016)
• Taulant Muka, Women’s health: implications of diet and cardiometabolic risk factors (PhD-defense:13-05-2016)
• Anna Vitezova, Vitamin D and cardiometabolic health (PhD-defense: 30-09-2015)
• Lisan Leermakers, Early life nutrition and cardiometabolic health across the life-course (PhD-defense: 13-05-2015)
• Ester de Jonge, Nutrition and body composition in the elderly (ongoing, expected defense in December 2016)
• Ilse Tromp, Early-life nutrition and respiratory outcomes (ongoing, expected defense in February 2017)
• Sanne Beth, Early-life determinants of celiac disease (ongoing since 2014)
• Sadaf Oliah Araghi, B-vitamins and age-related diseases (ongoing since 2015)

2. Dietary pattern analysis:
Dietary pattern analysis is an alternative approach to study the relationship between diet and the risk of chronic diseases; instead of looking at individual nutrients overall diets are studied. In 2012, I was one of the first to study specific dietary patterns in infancy and related health outcomes. Later, I have embedded this principle at the Epidemiology department and have applied it to various other research projects, such as with the development of food-based diet scores for specific health outcomes and the validation of pre-defined dietary guidelines (eg. the WHO and Dutch Healthy Diet guidelines), in close collaboration with other research groups and international consortia (i.e. CHANCES).

3. Timing of food introduction and food hypersensitivity:
In 2007, I have developed a food frequency questionnaire to assess gluten intake in infants which have been implemented in the PreventCD study (http://www.preventcd.com), a European multicenter trial on the influence of gluten introduction and the development of celiac disease. Later during my PhD, I have further studied the role of timing of food allergens in the first year of life and gastrointestinal and allergic outcomes. These results have recently been used for guidelines on the introduction of allergenic foods in the first year of life in Youth Health Care. (Click here for Dutch guidelines for Food Hypersensitivity). In 2014, together with Prof. Henriette Moll, I have received a grant from NutsOhra to study the effects of subclinical celiac disease which have led to a larger collaborative project with Leiden University MC to evaluate whether screening for celiac disease is justified in the general population.
