RESUMO

Despite the growing demand for green banana (GB) products, there is no review study regarding their potential health benefits. We aimed to compare the health benefits among different GB products by a systematic review. We researched six electronic databases (PubMed, EMBASE, Scopus, Science Direct, Web of Science, and Google Scholar) from inception to March 2019. We found 1009 articles in these databases. After duplicate removal, we screened 732 articles' titles and abstracts, and selected 18 potentially relevant studies for full-text reading. We added five records from the reference list of the fully-read articles and seven suggested by the expert. Twelve articles were excluded. In the end, 18 studies were considered for this systematic review. Ten studies were conducted with green banana flour and eight with the green banana pulp/biomass. Most of the GB health benefits studied were related to the gastrointestinal symptoms/diseases, followed by the glycemic/insulin metabolism, weight control, and renal and liver complications associated to diabetes. Only one study did not confirm the health benefit proposed. It is necessary to standardize the GB dose/effect to different age groups and different health effects considering the GB variety and ripeness level. Further studies are necessary to present better detailing of GB product and their health effects considering all the raw-material characteristics.

RESUMO

The consumption of raw vegetables is related to health benefits. However, these foods might be source of foodborne diseases. The objective of the present study was to perform a microbiological and parasitological evaluation of the leafy vegetables commercially sold in five regions of Brazil at public wholesale markets. The 12 types of leafy vegetables (144 samples) were curly lettuce, looseleaf lettuce, red lettuce, chives, coriander, kale, basil, arugula, parsley, iceberg lettuce, chicory, and bean sprouts. The prevalences of total coliforms (88 to 100%) and thermotolerant coliforms (37 to 100%) were high, but Salmonella was not detected in any of the analyzed samples. All open markets sold vegetables contaminated with enteroparasites, mainly Entamoeba sp., Balantidium coli, Strongyloides sp., Ascaris sp., Enterobius vermicularis, and Ancylostomidae. Contamination was detected in all the regions (north, northeast, central west, southeast, and south) and types of vegetables, with higher prevalences in the northeast region, mainly in basil, lettuce, and chives. Contamination of vegetables by potentially pathogenic microorganisms is a national problem, and the distribution centers should improve quality control of these commercial vegetables. Considering the high frequency of enteroparasites and bacteria and the potential risk of disease transmitted by vegetables, we suggest greater enforcement of the sanitary surveillance of food offered to the public.

RESUMO

In 2014, Brazil hosted one of the most popular sport competitions in the world, the FIFA World Cup. Concerned about the intense migration of tourists, the Brazilian government decided to deploy a food safety strategy based on inspection scores and a grading system applied to food services. The present study aimed to evaluate the results of the food safety strategy deployed during the 2014 FIFA World Cup in Brazil. To assess food safety, an evaluation instrument was applied twice in 1927 food service establishments from 26 cities before the start of the competition. This instrument generated a food safety score for each establishment that ranged from 0.0 (no flaws observed) to 2565.95, with four possible grades: A (0.0-13.2); B (13.3-502.6); C (502.7-1152.2); and pending (more than 1152.3). Each food service received a stamp with the grade of the second evaluation. After the end of the World Cup, a study was conducted with different groups of the public to evaluate the acceptance of the strategy. To this end, 221 consumers, 998 food service owners or managers, 150 health surveillance auditors, and 27 health surveillance coordinators were enrolled. These participants completed a survey with positive and negative responses about the inspection score system through a 5-point Likert scale. A reduction in violation scores from 393.1 to 224.4 (p < 0.001) was observed between the first and second evaluation cycles. Of the food services evaluated, 38.7% received the A stamp, 41.4% the B stamp, and 13.9% the C stamp. All positive responses on "system reliability" presented a mean of 4.0 or more, indicating that the public believed this strategy is reliable for communicating risks and promoting food safety. The strategy showed positive results regarding food safety and public acceptance. The deployed strategy promoted improvements in the food safety of food services. The implementation of a permanent policy may be well accepted by the public and may greatly contribute to a reduction in foodborne diseases (FBDs).
