[Historical tendencies of diet studies in Brazil].

The objective of this work was to conduct a historical analysis of diet studies in Brazil, from mid-XIX century to early XXI century. The method involved a bibliographical review to identify and analyze the different kinds and main results of surveys on food consumption in the country, by means of six intentionally established transversal cuts (1837-1899; 1900-1929; 1930-1939; 1940-1969; 1970-1989 e 1990-2005). Several methodological procedures to evaluate individual and population diets were found: food history; 24-hour dietary recall; food intake diary or register; food weight and measures; food intake frequency questionnaire, and research on food budget. We conclude that food consumption evaluation methods and tools have improved simultaneously to deep and substantial changes in consumption patterns and food habits among the Brazilian population.
