Coalho cheese is a dairy product typical of the Northeast region of Brazil and widely consumed by the population; however, the poor quality of the raw material used in association with the absence of standardization in the manufacturing process makes it susceptible to microbial contamination, mainly by Staphylococcus aureus. The objective of this study was to evaluate the influence of chitosan as a coating and incorporated in coalho cheese on S. aureus viability and the sensorial acceptance of the cheese. For this, coalho cheeses were made with chitosan in the coating or added to the curds at 5 mg mL-1, 10 mg mL-1 and 15 mg mL-1 and 1 mg g-1, 2 mg g-1 and 4 mg g-1, respectively. Products without chitosan (C) and 1% acetic acid (CA) were used as controls. The bacterial inhibition of chitosan in the artificially contaminated samples was assessed by comparing the viable cell count of S. aureus (ATCC 6538) in each treatment over five time intervals (0, 4, 8, 12 and 16 d storage). Product C was evaluated for moisture and fat content. The sensorial and shelf stability analyses were performed with the control and chitosan treated samples at the most efficient antibacterial concentrations. The sensorial analyses were performed with 100 consumers. Chitosan antimicrobial activity was observed in all treatments; however, the highest concentrations of chitosan added as a coating and to the cheese, 15 mg mL-1 and 4 mg g-1, respectively, inhibited S. aureus. The moisture and fat contents met the standards established by the Brazilian legislation. Regarding stability, the samples complied with the regulatory microbiological limits and presented acceptable pH, acidity and water activity values. As far as sensorial acceptance was concerned, the scores corresponded to hedonic concepts between "I liked it slightly" and "I liked it a lot", with an improvement in the texture of the products when chitosan was incorporated. Acceptability values were higher than 70%, except for the taste the products with chitosan covering them, which was 68.3%. It can be inferred from the results that the use of chitosan as a coating and incorporated in coalho cheese is a favourable alternative for the preservation of this product and has potential commercial applicability.

Seguindo a tendência mundial, nas últimas décadas, o Brasil vem passando por um processo de transição demográfica, epidemiológica e nutricional, caracterizado pelo declínio da taxa de fecundidade, diminuição no ritmo do crescimento populacional, aumento da longevidade, progressiva urbanização, maior exposição a comportamento alimentar e estilo de vida inadequado além de mudanças nos padrões saúde/doença. As modificações na estrutura da dieta da população têm levado a um aumento significativo do consumo de alimentos processados e ultraprocessados, ricos em açúcares, gorduras, corantes e sódio e também na redução do consumo de alimentos naturais. A alimentação inadequada associada ao estilo de vida sedentário tem resultado em um aumento de indivíduos com excesso de peso e susceptíveis a Doenças Crônicas Não Transmissíveis (DCNTs). Diante disso, o objetivo do estudo foi identificar evidências disponíveis na literatura acerca da influência da transição alimentar e nutricional sobre o aumento da prevalência das DCNTs. Para tanto, foi realizada uma revisão narrativa com dimensão temporal entre 2000 e 2021 nos idiomas português e inglês. Os dados obtidos evidenciaram que as mudanças no padrão alimentar associadas com o sedentarismo tem repercutido em um aumento considerável da prevalência de obesidade, Diabetes Mellitus (DM), Doenças Cardiovasculares (DCVs), Hipertensão Arterial Sistêmica (HAS) e dislipidemias. Em consequência dos hábitos alimentares inadequados e estilo de vida sedentário, verifica-se a necessidade das pessoas serem orientadas quanto a uma alimentação saudável, e também estimuladas a praticarem exercício físico regularmente para ter uma melhor qualidade de vida.

Endocrine Disruptors (EDs) are substances that influence the organic activities of the endocrine system of the human body. In recent decades, there has been increasing interest from the scientific community and the media about the possible harmful effects caused to humans by exposure to these chemicals. This study aimed to conduct a systematic literature review on the concepts of these chemicals, their effects on human health and mechanism of action. A bibliographic survey was conducted through the Virtual Health Library (VHL) and Scielo, institutional website and books between 1999 and 2019, in portuguese and english. The data obtained indicated the impact of EDs on obesity, diabetes, cardiovascular system, polycystic ovary syndrome, carcinogenicity and thyroid system. Thus, EDs are substances that affect human health, since several studies indicate endocrine interference of these substances, which impact on organism damage.
