OBJECTIVE: To determine fluoride concentrations in the typical Brazilian meal (rice with beans) and in processed infant foods, and to estimate their contribution towards dental fluorosis. METHODS: The foods were purchased at supermarkets in the cities of Piracicaba and Campinas, Southeastern Brazil. The processed infant foods were bought in 2001 and the rice and beans in 2003, and they were analyzed immediately. Three brands of rice, three brands of beans and 36 samples of infant foods were analyzed, divided into […]

OBJECTIVE: To evaluate the agreement between macronutrients and food energy values analyzed in laboratory and data of food composition tables and software available in Brazil. METHODS: Eleven types of food were analyzed totaling 701 samples. Student’s t-test was performed consisting of the comparison between the mean values obtained in laboratory and the unique constant value of each table or software at 5% confidence level. RESULTS: It was noted that depending on the type of food, nutrient and table or software […]

OBJECTIVE: To determine the total fluoride dose to which children were exposed during the critical age of developing dental fluorosis, in an optimally fluoridated region, having diet (liquids and solids) and dentifrice as fluoride sources. METHODS: For the pilot study, 39 children (aged 20 to 30 months) were selected from a day care center in Piracicaba, Brazil. They drank and ate food prepared with fluoridated water. To determine the total dose of fluoride exposure, duplicate-plate samples and products from tooth […]
