Non-communicable diseases (NCDs) are responsible for two-thirds of premature deaths in Europe. This added to the European socio-economic scenario already weakened by the vital aging of the population, contributes to the loss of active individuals, weakening competitiveness and social and economic sustainability, thus making the prevention of NCDs a European objective. Preventing NCDs with the enrichment of the food environment using algae or their compounds, which are rich in nutrients and bioactivities, is an excellent way to promote healthy eating of ecological and sustainable foods. This strategy generates social, economic, and environmental gains, as well as improvements in health and sustainability. The objective of this study was to verify whether the intake of the recommended dose of fiber caused a decrease in the number of deaths caused by NCDs. The NCD prime scenario modelling tool was populated with demographic data on mortality and food intake for 2016. The results obtained by applying the NCDprime model suggested that with the recommended fiber dose, 4.5% of deaths were averted, and about 30 million euros were saved. The number of prevented deaths and the potential for cost savings represent significant health and economic gains. It will allow, in the future, new health policies to be equated with an adaptation of the food ecosystem and the development of new functional foods.
