Who is Marieke de Zwaan?

Marieke de Zwaan (1976) grew up in a family deeply connected to the agricultural world. She graduated from TU Delft in 2001 and subsequently worked as an architect for various multinational corporations. For ten years, she traveled the world with her husband and three sons, living in America, Australia, and Brazil. During her travels, she transformed from a state of chronic illness (burnout, migraine) to one of optimal vitality by changing her diet.

Marieke has pursued various studies in the fields of nutrition, vitality, and systemic work (family constellations). For over a decade now, she has been guiding individuals facing personal challenges. As a passionate keynote speaker, her lectures and webinars have positively inspired thousands of people both domestically and internationally to make more conscious dietary choices.

However, her keynotes also contain confrontational and poignant insights that provoke thought among the audience because Marieke de Zwaan aims to touch people deeply. This human aspect, for her, is the best way to underscore the importance of healthy nutrition.


"Theory can provide you with a lot of knowledge, but to get to the essence, you will need to open your heart."

According to Marieke, nutrition is often approached in such a reductionist manner, solely viewed through the lens of nutrients. However, nutrition is so much richer than that. A quote that resonates deeply with Marieke to her core is the following: 'Food is not rational. Food is culture, habit, craving, and identity.' Only when you pay attention to everything connected with nutrition, does nutrition start working for you!
