The Use of Biometrics in Testing the Perception of a Selected Indicator of the Nutritional Composition of Food

Abstract

Poor eating has a direct impact on increasing the percentage of overweight and obese people in the global population. It is scientifically proven that obesity directly increases the risk of human health problems (cardiovascular, oncological diseases), which ultimately leads to higher health care costs. In this context, it is a society-wide problem. This is the reason why a change in eating habits must be a priority and a subject of interest in the global understanding. Knowing the process of consumer behavior when buying food creates room for influencing towards healthier products or a balanced diet. The point of sale is the last place that can influence the consumer. The aim of food indicators is primarily to point out the balance of diet, or healthier alternatives, but in no case the complete elimination of consumption of products that achieve worse nutritional scores. There are several models of nutritional indicators on the market that have their advantages and disadvantages. The fact is that successful is the one that is generally accepted by producers, retailers, and by consumers. The paper examines the perception of the Nutri-score food indicator on a selected well-known product using consumer neuroscience tools and an online platform. Finally, the paper points to the perception of the food indicator as well as its effectiveness in terms of changing consumer preferences.
