Perceptions about sustainability and healthy food choices are closely linked, as a study at the University of Konstanz shows.
Many people are keen on making healthy as well as sustainable food choices, and they often intuitively equate "healthy" with being "sustainable". A study by researchers at the University of Konstanz, the Johannes Kepler University Linz and the Hamburg University of Applied Sciences is focusing on whether or not this perception corresponds to reality. It has just been published in the scientific journal PLOS Sustainability and Transformation.
The study shows that many consumers clearly correlate their perception of sustainability with how healthy their food choices and meals are. "We examined just how widespread the perception is that healthy meals are also sustainable. We were especially interested in whether perceptions change based on the actual overlap between meal health and sustainability. We also explored whether the type of meal, such as a vegan meal, influences this presumed correlation", explains Professor Gudrun Sproesser, head of the Department of Health Psychology at Johannes Kepler University.
In the study, over 5,000 customers rated 29 different meal options at a public canteen – i.e. the University of Konstanz’s canteen, run by Seezeit student services – as to what they believed to be a healthy and sustainable food choice. The exact values relating to environmental sustainability and healthy eating were also determined by applying a special algorithm to analyze the precise meal recipes. The findings were clear: Many participants automatically believed that healthy food was also sustainable.
