In 2014/2015, the first Swiss National Nutrition Survey, menuCH, was conducted in a sample of about 2000 participants. These participants provided detailed information about what they eat and drink. In our project, menuCH data from will be analysed in order to assess cultural differences between language regions of Switzerland with respect to consumption, dietary patterns, and associated lifestyle factors. Differences in consumption of meat and meat products; milk and dairy; and beverages, will be compared to nutritional recommendations and assessed for evidence-based benefits and risks. Data-driven dietary patterns of menuCH data will be generated, compared with established dietary patterns such as a Mediterranean Diet or the Healthy Eating Index, and related to regional prevalence/mortality of chronic non-communicable disease. Dietary information from Swiss Health Survey will be validated with corresponding menuCH data for food and beverage intake and by comparing associations between anthropometric parameters and dietary patterns with socioeconomic/demographic factors.
