Abstract The objective of this study was to identify and discuss the tools for the promotion and evaluation of adequate and healthy eating based on the Food Guide for the Brazilian Population. The scoping review was conducted according to the JBI Manual for Evidence Synthesis via the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist and by searching PubMed/MEDLINE, EMBASE, SciELO and LILACS. Sixteen studies on relevant tools, based on the food guide for individuals of all age groups, were thus included: two descriptive studies, two randomized clinical trial protocols, eleven methodological analyses, and one psychometric paper, aimed at either a focal population (n=12) or health professionals (n=4). Six studies addressed tools for promoting adequate and healthy eating, and ten developed tools for evaluating dietary practices or the knowledge and activities of health professionals. This review can therefore assist health professionals in choosing instruments for the implementation and/or dissemination of food guide recommendations, contributing to the promotion of adequate and healthy eating habits.

Abstract Objective: To elucidate the acute effect of different high-fat meals accompanied by water or orange juice on subjective appetite sensations. Methods: This acute, postprandial study included 39 healthy women (aged 20 to 40 years): 22 participants received a high-monounsaturated fat meal (MUFA) (≈1000 kcal, 56.3% Energy from MUFA) and 17 participants received a high-saturated fat meal (SFA) (≈1000 kcal, 37.6% Energy from SFA). Both interventions were accompanied by 500 ml of water or orange juice. The subjective appetite sensations were evaluated before (fasting) and 1, 2, 3, 4, and 5 hours after the meal intake using the visual analog scale. Results: The subjective area under curve (AUC) appetite sensations and AUC appetite scores were equal after the consumption of high-fat meals from SFA and MUFA. Moreover, the consumption of a high-SFA meal raises the prospective desire to eat something fatty. In addition, the high-SFA meal consumption reduces subjective AUC appetite sensations and AUC appetite scores along the time, compared to a high-MUFA meal, when orange juice consumption followed those meals. Conclusion: Our results demonstrate that high-MUFA meal consumption decreased the desire to intake something fatty, and the high-SFA meal, when followed by orange juice intake, has postprandial appetite sensations suppressed.

RESUMO CONTEXTO E OBJETIVO: A dieta é um importante fator modificável envolvido na inflamação induzida pela obesidade. Nós revisamos ensaios clínicos que avaliaram o efeito do consumo de diferentes ácidos graxos sobre a expressão de genes relacionados com a inflamação, tais como citocinas, adipocitocinas, quimiocinas e fatores de transcrição. TIPO DE ESTUDO E LOCAL: Estudo de revisão narrativa realizado em um centro de pesquisa. MÉTODOS: Revisão do efeito da ingestão de gordura sobre a expressão de genes envolvidos com inflamação em seres humanos. RESULTADOS: O consumo do ácido graxo saturado (AGS) foi relacionado com a regulação favorável pós-prandial de genes associados com vias pró-inflamatórias nas células mononucleares de sangue periférico (CMSP), em comparação com a ingestão do ácido graxo monoinsaturado (AGMI) ou do ácido graxo poli-insaturado (AGPI). Além disso, o consumo agudo de uma dieta com alto conteúdo de AGS também induziu uma resposta pró-inflamatória pós-prandial para vários genes da inflamação no tecido adiposo subcutâneo. Ambas as dietas com alto conteúdo de AGMI e AGPI apresentaram perfil anti-inflamatório ou, pelo menos, menor resposta pró-inflamatória em relação ao consumo de AGS. Contudo, os resultados são controversos acerca do melhor substituto para o AGS, devido à grande variabilidade na dose de AGMI (20% a 72% da ingestão energética) e AGPI n3 (0,4 g para 23,7% da ingestão energética) utilizados nos estudos de intervenção. CONCLUSÕES: O perfil lipídico da dieta pode modular os genes relacionados com inflamação pós-prandial e a longo prazo em CMSP e no tecido adiposo. Identificar o perfil lipídico ideal no controle inflamatório pode ser uma abordagem promissora para o tratamento de doenças crônicas como a obesidade.

ABSTRACT CONTEXT AND OBJECTIVE: Diet is an important modifiable factor involved in obesity-induced inflammation. We reviewed clinical trials that assessed the effect of consumption of different fatty acids on the expression of inflammation-related genes, such as cytokines, adipokines, chemokines and transcription factors. DESIGN AND SETTING: Narrative review study conducted at a research center. METHODS: This was a review on the effect of fat intake on inflammatory gene expression in humans. RESULTS: Consumption of saturated fatty acids (SFAs) was related to postprandial upregulation of genes associated with pro-inflammatory pathways in peripheral blood mononuclear cells (PBMCs), in comparison with monounsaturated fatty acid (MUFA) or polyunsaturated fatty acid (PUFA) intake. In addition, acute intake of a high-SFA meal also induced a postprandial pro-inflammatory response for several inflammatory genes in subcutaneous adipose tissue. Both high-MUFA and high-PUFA diets showed anti-inflammatory profiles, or at least a less pronounced pro-inflammatory response than did SFA consumption. However, the results concerning the best substitute for SFAs were divergent because of the large variability in doses of MUFA (20% to 72% of energy intake) and n3 PUFA (0.4 g to 23.7% of energy intake) used in interventions. CONCLUSIONS: The lipid profile of the diet can modulate the genes relating to postprandial and long-term inflammation in PBMCs and adipose tissue. Identifying the optimal fat profile for inflammatory control may be a promising approach for treating chronic diseases such as obesity.

The labneh or labaneh is a popular fermented milk in the Middle East. Another fermented product that deserves special mention is kefir since it has probiotic activity and unique sensory, nutritional, and therapeutic properties. The aim of the present study was to develop a functional probiotic labneh using kefir as a fermenting agent and to perform a sensory analysis of the obtained product. Kefir was obtained by growing grains in pasteurized milk. Samples of skimmed and whole labneh were prepared from the inoculation of 5% kefir milk (skimmed/whole) at 28 ºC for 24h, followed by cooling (12-18h) and whey drainage (12-24h), both at 4 ºC. Sensory analysis was performed with 70 untrained panelists using a 9-point scale hedonic in the acceptance tests. The paired t-test was used to compare the differences between the means of the scores obtained, with the significance level of 5%. The labneh prepared showed good acceptance by the judges, and the whole labneh samples had the highest scores in the acceptance test. Further studies on the analysis of microbiological viability, nutritional composition, and determination of shelf life, also to improve acceptability of the low-fat version of the product, are needed.

Petit suisse é um queijo de consistência pastosa. O kefir é um produto resultante da simbiose entre bactérias ácido-láticas e leveduras, e apresenta ação probiótica, como imunomodulação e balanço da microbiota intestinal. O presente estudo buscou desenvolver petit suisse de kefir. Os grãos foram cultivados no leite de vaca pasteurizado e, após separação do kefir, seguiu-se para dessoragem e preparo do petit suisse nos sabores morango, mangaba, ervas e tomate seco. Com escala hedônica estruturada de nove pontos, avaliou-se aceitação pela ANOVA. As amostras doces e salgadas foram comparadas por meio do teste t de Student e a intenção de compra foi avaliada por meio do teste de médias e de distribuição das frequências. As amostras apresentaram boa aceitação pelos julgadores. O produto pronto apresentou baixo rendimento, mas pode ser reproduzido em nível domiciliar com baixo custo. A análise da composição nutricional e a variação dos sabores e da faixa etária dos julgadores apresentam-se como alternativas para outros estudos.

"Petit Suisse" is a creamy cheese. Kefir is a symbiotic mixture of lactic acid bacteria and yeasts with probiotic activity including immunomodulation and balance of intestinal microflora. The present study aims to develop "Petit Suisse" cheese from kefir. Kefir grains were grown in pasteurized cow milk, and after the separation of kefir the serum was discarded and the "Petit Suisse" cheese was prepared using strawberry, mangaba, herbs, and dried tomatoes. The acceptance of the different preparations was evaluated using a nine-point hedonic scale followed by ANOVA. The sweet and salty products were compared by the Student's t-test. Purchase intent was evaluated by the means test and frequency distribution. All products were well accepted by the judges. The product was characterized by low yield, but it can be prepared at home at low cost. The nutritional composition analyses and the variety of flavors as well as the range of age of the judges are alternatives for further studies.
