In 1962, the Supply Book was created by decree in Cuba and, since then, few Cubans imagine the food performance of their household without this document. So, it presented a basic food basket as part of the central and planned economy. Although, initially, it had a direct monetary and product subsidy from the Soviet Union, after the dissolution of the latter, the contents of the passbook were drastically reduced. Over the years, the notebook continued to lose prominence in its essential supplies, for example, in 2009 it again suffered a cut in grains, salt and tubers, and a year later the quota of cigarettes was definitively eliminated, which went to a regulated free sale.  

Currently there are around 3,809,000 family units registered in the booklet system, grouping more than 11 million Cubans. The products of the notebook are variable according to geographical area and may be subject to administrative, production and transportation errors of their products, as well as the actual availability and import capacity of the country. Despite this, during the last two years the notebook has been not only a management document for the delivery of regulated food, but also for the regulation of donations and other controlled, but not subsidized, products within the emergency policies by the COVID-19. As the economic crisis has worsened, Cuban households have once again become more dependent on this document, showing an increase in its registration, as an instrument of surveillance and social regulation, as well as the normalization of food insecurity.

The Food Monitor Program conducted semi-structured interviews to obtain information on the food experiences of Cuban citizens around the supply book, their purchasing power, dependence on subsidies, perception of well-being and food security, bartering and survival dynamics, among others.
