One of the measures taken to improve the food consumption level of the most vulnerable population groups, has been a certain standardization of food consumption patterns throughout the various social or income sectors; i.e. the typical diet of specific urban sectors is nowadays less varied (low-income sectors eat less beef, while processed food is less readily available to middle-income sectors). 84. Other studies carried out in the rural area of Managua revealed that peasants belonging to co-operatives had changed their diet, which prior to the revolution had mainly comprised rice, beans, maize and cassava; on account of higher income as a result of access to land, credit, etc., they tend to consume a greater amount of meat and perishable products. 85. The same study found that the State policy of democratizing food supply had facilitated access to a range of calorie-rich foods. This has made for acceptable levels of calorie intake for lower-income families and no great change has been identified in calorie consumption by income group. Quite the opposite has occurred as regards protein intake: higher-income families consume more than the recommended levels of products such as meat, milk and eggs, which are rich in protein and which have not been subject to price regulation policies or planned supply; low-income families consume less than the minimum. 86. Generally speaking, the study on consumption in the districts of Managua found that the average calorie and protein intake of the families studied stood at the recommended levels. However, within the lower-income groups, they only amounted to 80 per cent of the recommended level, while in the higher-income categories the levels of calorie and protein intake were respectively 120 and 140 per cent of those recommended. 11. Measures adopted to reduce food adulteration and contamination, and to
analysis: The text discusses the impact of the revolution on food consumption patterns in Managua, specifically focusing on the diets of different income groups. It highlights changes in food consumption, including the standardization of diets, access to calorie-rich foods, and disparities in protein intake between low- and high-income families. This suggests that the text is primarily concerned with the social and economic aspects of food consumption, rather than natural resources, environment, or scientific/technological aspects.
