| O consumo de bebidas carbonatadas no Brasil é elevado e não existem dados sobre os teores de sódio neste tipo de bebida comercializada no país. O presente trabalho examinou 97 amostras de refrigerantes compreendendo 14 marcas e 7 tipos de bebidas (cola, guaraná, limão, laranja, uva, soda e água tônica). Os teores de sódio encontrados variaram de 19 a 202mg Na/L. As bebidas adoçadas com açúcar apresentaram uma média de 74 ± 13mg Na/L e as bebidas com adoçantes artificiais, uma média de 151 ± 39mg Na/L. Portanto, os refrigerantes adoçados artificialmente fornecem cerca de duas vezes o teor de sódio das bebidas adoçadas com açúcar. Como conseqüência, um consumidor médio de refrigerantes (259mL/dia) poderá ingerir por dia cerca de 19mg de sódio provenientes do... |

| The elements called heavy metals when ingested are not completely eliminated from animal bodies and are responsible for chronic and acute intoxications. Sixty-three samples of beer, produced in the states of São Paulo, Paraná, Rio de Janeiro, Rio Grande do Sul, Minas Gerais, and Pará, were analysed for lead and cadmium content by atomic absorption spectrometry with graphite furnace atomization and Zeeman correction. The concentrations of Pb and Cd of dark differed significantly from light beers, being higher in the former. No significant difference was found between the beers produced in predominantly rural areas and the ones produced in industrialized areas. The concentrations of lead and cadmium in all samples were bellow the maximum accepted by present... |

| Tomatoes are highly susceptible to fungi contamination in the field, during transportation, processing, and storage. Aspergillus flavus and Aspergillus parasiticus have been isolated from tomatoes and tomato products, and both fungi species can produce aflatoxin, mycotoxin with hepatotoxic, carcinogenic, teratogenic, and mutagenic effects on all animal species tested so far. In order to verify a possible aflatoxin contamination of tomato products commercialized in Brazil, 63 samples of tomato products (pulp, paste, purée, ketchup, dehydrated tomatoes, and dried tomatoes preserved in oil) produced in 5 Brazilian states and 1 imported sample (ketchup), totalizing 29 brands, were analyzed by thin layer chromatography. The analytical method showed an average... |
