RESUMO

Observed changes in eating and drinking behaviors in economically developing countries are associated with increase of obesity and related chronic diseases. Researchers from field of public health (PH) have attributed this problem to food processing and have created new food classification systems to support their thesis. These classifications conceptually differ from processing level concepts in food science, and state to people that food processing is directly related to nutritional impact of food. Our work aims to compare the concept of food processing from the standpoint of food science and technology (FST) and public health and to discuss differences related to formulation or level of processing of products and their impact on nutritional quality. There is a misconception between food processing/unit operation/food technology and formulation or recipes. For the public health approach, classification is based on food products selection and the use of ingredients that results in higher consumption of sugar, sodium, fat, and additives, whereas in FST, processing level is based on the intensity and amount of unit operations to enhance shelf life, food safety, food quality, and availability of edible parts of raw materials. Nutritional quality of a product or preparation is associated with formulation/recipe and not with the level of processing, with few exceptions. The impact of these recommendations on the actual comprehension of food processing and quality must be considered by the population.

RESUMO

The efficacy of quinine for the treatment of falciparum malaria was studied by quadriennal analysis of the medical records of 454 patients admitted to the HDT-GO from 1983 to 1994 and treated with identical doses of quinine alone for 7 days. In the quadriennium from 1983 to 1986, 98.4% of the patients became negative by the 5th day of treatment and 8% presented recurrence (R1); from 1987 to 1990, only 72.9% became negative by the 5th day of treatment, 1.4% remained positive until the 7th day (R2) and 9.7% presented recurrence (R1); from 1991 to 1994, 70.1% became negative by the 5th day of treatment, 3.5% remained positive until the 7th day (R2) and 20% presented recurrence (R1). The increase in parasite clearance time with failure up to the 7th day of treatment (R2) and the increase in recurrence (R1) show that P. falciparum is developing resistance to quinine in the region under study.
