    Abstract:
    Data from a household expenditure survey of 1,200 Manaus families performed by the Amazonas State Government in 1973-74 are analyzed by income group. The per cent frequency of families buying different foods and the daily per capita consumption of each were calculated. The daily per capita intakes of energy, protein, vitamin A, thiamine, riboflavin, nicotinic acid, ascorbic acid, calcium, phosphorus, iron and zinc were estimated and their adequacy evaluated. In contrast to the south and northeast of Brazil, the main bulk of the diet was derived from cereals and fish. The quantities of eggs, meats, fruit and vegetables consumed per person, increased 50-100% as income improved, whereas fish consumption decreased 30%. The nutrients quantitatively most deficient were zinc, vitamin A, calcium, thiamine and riboflavin, with 60-80% of low and middle income families not achieving safe levels of intake for zinc and vitamin A. The beneficial effect of income on the adequacy of calcium, thiamine and riboflavin intake was quantitative. For zinc and vitamin A, increased income was associated with a qualitative improvement in the diet, principally due to the increased consumption of meat and liver. These results are discussed in relation to existing clinical evidence of deficiency states in the region.
