## 3 Results and Discussion
This suggests that the use of local products represents a positive factor that together with the improvement of other components (e.g., reduction in the use of fossil fuels), could contribute to a healthy environment. In this regard, our approach fits well into the contemporary challenge aimed at expanding research on the production and consumption of sustainable local food [51]. The consumption of sustainable products would have positive effects on various aspects, first environmental, but also social, economic, and human health aspects [51]. As for the last aspect, it is known that a healthy environment is the basis of a healthy life, and an unhealthy environment contributes to the onset of various non-communicable diseases (NCD), such as stroke, heart disease, cancer, and other chronic diseases [52]. Based on these results and the rules governing the health claims sector [43], nutrient quality labels (SANI labels) and a sustainability label (carbon footprint label) were designed that were easily recognizable to consumers. As shown in Figure 3, the SANI labels consisted of specific colorful marks that were assigned to each healthy nutritional component. Interestingly, these labels were equipped with a QR code, intended to be useful to consumers by allowing them to access real-time information in order to enrich their shopping carts with many healthy products, making it possible to achieve a balanced, healthy, complete, and sustainable diet. This, along with communication of the obtained data, the dissemination activity, an innovative online e-commerce platform, and through optimal shelf marketing, led to a considerable increase in conscious purchasing. Indeed, before the SANI survey, the results showed that people would like to live a healthy life by consuming natural food, but that their knowledge about healthy natural food was conflicting, thus affecting their choices. Indeed, an analysis of the distribution of the responses to the questionnaire (Table 2) based on age groups was conducted (Figure 4), and this revealed how age can affect certain choices and awareness. For example, most interviewees (60% of the total) considered natural food as \"whole food, without any human intervention\", or \"as natural, thus you can trust\" (10%). Only 30% of interviewees considered natural foods as \"organic foods\" rich in healthy nutritional components. \begin{table}
