Popis: Homestead aquaponic production has been proposed as a reasonable alternative for obtaining food within the framework of the circular economy. However, little is known about the ability of homestead aquaponics to contribute to a healthy diet and the savings it represents on the cost of such diets for inhabitants of economically depressed communities. In the present work, based on a case study, the nutritional contribution of vegetables and fish produced in one year has been calculated, with the goal of determining the contribution of aquaponics to the healthy diet of an adult during this study period. The amount of external food products that should be purchased, the nutritional contribution of the complete diet (comparing it with that of a Mediterranean diet), and its cost have also been determined. The results show that achieving a balanced diet in macronutrients, minerals and essential nutrients with aquaponics is feasible, with a real cost of about 3.07 euros per person per day, amounting to a mean savings of 22% compared to the market price of food. The percentage of nutrient contribution of aquaponic foods exceeds in most cases 20%, being especially high for protein, dietary fiber, some minerals such as potassium, and vitamins.
