In September, Brazil and the world celebrated an event that despite the millennial resilience of its study problem, is changing the course of its own civilization: the 75 th anniversary of a prophetic and even revolutionary book, Josué de Castro's, The Geography of Hunger. 1 In fact, only now, three quarters of a century later, we gain the temporal perspective to understand the anticipation of the future and, therefore, its prophetic dimension and the apostolic militancy of its author, who adopted a fight against hunger as a major cause of his own life. In this missionary commitment, alongside a strength of faith, the author invests himself with an apostolic (or at least heroically militant) charge: the universal right to access basic food as a fundamental attribute of citizenship. This would be the ethical principle of food and nutritional security that Brazil has adopted in its own constitution, which is in our Carta Magna 2 (Magna Letter).The Geography of Hunger was generated, emerged, consolidated, and, above all, multiplied as a book in continuous replication of human and universal messages, more than the object of a medical-social theme, overcoming the chains of conduct in political doctrines at the time, in geographic space of ideological and political schemes and founded as a counter-culture: the transnational and pangeographic human right, with the most elementary right to healthy food. It all begins (but does not end) when, as a physician in an industry, Josué de Castro observed that the matrix disease of almost all the illness of the body was hunger. A food survey of 700 families in a neighborhood in Recife extended to domestic costs with housing, clothing, schooling, transportation and health, thus constituted an integral sketch of what would be the current family budgets, starting from the elementary observation that in a standard family at the time (1932) father, mother and five children constituted a unit of irrefutable and universal demands. 3 And, in a perspective then, still futuristic, leisure itself is, or would be a basic need. Thus, we approach a cost very close to what would be a basic salary for family expenses and their essential demands with the acquisition of 12 food items referring to the demands on calories, proteins, vitamins, minerals, (macro and micronutrients) and their functions isolated and combined in a harmonic and physiologically appropriate manner. 4 It was an enormous advance, at a time when even the rich and politically and culturally developed countries were involved in issues that were still so primitive, such as hunger, food insecurity, and a whole structure of adversities, which can be enunciated in the so-called "ecosystem" of poverty. It is a process sustained by the instability of employment and income, by precarious housing and sanitation conditions, by the limited supply and low quality of health actions, by the culture of poverty and even indigence that scatters around the world niches of families united or stigmatized by the apparent fatalism of poverty.It is cl...
