Susanne Merz

Susanne Merz finished her studies in 1997 with a master in ecotrophology and joined YWAM in 2002. Within her profession she has almost 12 years of experience with YWAM Herrnhut, Germany in pioneering and leading the kitchen and coming alongside people who have struggled with eating disorders. Also taught on nutrition in schools like Biblical Christian Worldview or Primary Health Care at different YWAM bases in Germany, Switzerland, France, USA, Russia and Cambodia.

(Ecotrophology is a branch of nutritional science concerned with everyday practice. It is mainly in Germany that it is seen as a separate branch of health care, and the word is rare outside Germany. Ecotrophologists are specialists in nutrition, household management and economics. This includes physiological, economic and technological principles on healthy nutrition and practical application. They work in many different fields: management of the above types of operations, development of new nutritional concepts in catering, quality control in food manufacturing and processing, operations and research within the food industry. Due to the interdisciplinary nature of the training, ecotrophologists often take a coordinating role in Facility Management companies.)
