Título: Dairy consumption in food-based dietary guidelines: insights from the americas. Autoria: COSTA, N. A. da S.; SIQUEIRA, K. B.; NALON, G. A.; DUTRA, J. P.; DESTRO, L. Conteúdo: Milk and dairy products are widely recognized for their nutritional contributions, providing bioavailable calcium, protein, and micronutrients essential for human health, while also playing a significant socio-economic role in many countries. Food-Based Dietary Guidelines (FBDGs) serve as policy instruments to promote healthier dietary patterns, yet the way dairy is represented within them varies substantially across the Americas. This study aimed to analyze how dairy is addressed in national FBDGs across the region, identifying consistencies, gaps, and divergences. A descriptive and comparative documentary analysis was conducted using official national dietary guidelines published or endorsed by government institutions between April and May 2025. Guidelines were included if they contained explicit or implicit recommendations on milk and/or dairy consumption for healthy adults. To enable crosscountry comparisons, recommendations were standardized into milk equivalents (mL/day), with conversion factors applied for cheese and yogurt. Recommendations were then classified by type (quantitative or qualitative), intake volume, and subgroup-specific guidance. The analysis revealed marked heterogeneity. North American countries, particularly the United States and Canada, provided structured, quantitative recommendations of 600–800 mL/day, with subgroup-specific adjustments. Several Latin American countries, such as Argentina, Mexico, and Costa Rica, issued quantitative but less detailed guidance (400–600 mL/day). Conversely, many Central American and Caribbean countries included only qualitative statements or omitted dairy altogether. A notable finding was Brazil’s absence of quantitative dairy recommendations despite being the region’s largest producer and consumer, reflecting its guidelines’ emphasis on dietary patterns rather than food group servings. In conclusion, dairy-related recommendations in the Americas are fragmented, shaped by cultural traditions, policy priorities, and health concerns. While structured guidance can support nutrient adequacy, its absence may hinder public health goals. Regional dialogue and evidence-based, context-sensitive strategies are needed to strengthen dietary guidance, address inequalities, and ensure adequate nutrient intake across the continent.

Título: Consumers’ perception of milk and dairy products in Brazil. Autoria: RODRIGUES, L. D.; SIQUEIRA, K. B.; MINIM, V. P. R. Conteúdo: Milk and dairy products are traditionally recognized for their nutritional and health benefits, yet little is known about how consumers perceive them. Understanding consumer attitudes, beliefs, and associations is crucial, as such perceptions influence purchasing decisions, acceptance, and consumption patterns. This study aimed to investigate consumers’ perception of milk and dairy products in order to define the current image of these products within the diet and explore opportunities for sectoral development. The research applied an online survey using the Free Word Association technique to capture spontaneous perceptions related to the main consumed products in Brazil, including milk, yogurt, cheese, butter, and condensed milk. Data were analyzed to identify the most frequent attributes, symbolic associations, and potential directions for product positioning. Results indicated that milk and yogurt are strongly associated with health, nutrition, and everyday consumption contexts. Cheese and condensed milk emerged with an indulgent and cultural image, with cheese linked to taste and versatility, being consumed alone or in pairing and recipes, while condensed milk was only related to recipes and taste. Butter was also predominantly perceived as an ingredient, but it was focused on daily cooking. Overall, the findings highlight how consumer perceptions can be strategically leveraged to orient marketing approaches, strengthen communication initiatives, and inspire innovation in product development. By uncovering the symbolic and functional roles attributed to different dairy products, this study contributes to guiding the dairy sector in creating more consumer-oriented strategies and enhancing its market value.

Título: Cognitive heuristics in consumers negative perceptions of dairy products in digital environments. Autoria: LOPES, B. E. A. J.; SIQUEIRA, K. B.; MENDES, K.; NOGUEIRA, T.; DESTRO, L. Conteúdo: Social media has become a privileged space for the circulation of information on various topics, exerting a growing influence on individual and collective perceptions. In this environment, users often resort to cognitive heuristics, i.e., mental shortcuts that simplify judgments and decisions, but which can also induce systematic biases. This study sought to identify and classify cognitive heuristics in digital discourse related to dairy products on platform X (formerly Twitter), based on a corpus of more than 400,000 negative posts collected and processed using Voyant Tools software. The methodology involved three steps: (i) selection of the most frequent words in a lexical cloud, (ii) investigation of contexts of use, and (iii) categorization of occurrences into thematic subgroups of economics, affect, anchoring, loss aversion, and availability. The results showed that dairy consumption is often associated with outrage over prices, emotional ties, and value frustrations. Everyday language has cognitive and emotional patterns that, although spontaneous, can induce distorted or biased perceptions on the part of consumers, negatively influencing their evaluation of products.

Título: Avaliação de protótipos de nanossistemas imunomoduladores sobre o desempenho reprodutivo de Rhipicephalus microplus alimentados em bovinos tratados. Autoria: MOREIRA, L. dos S.; APONTE, P. F. C.; PAULA, L. S. M. de; MONTAÑA, J. E. L.; CAMPOS, M. M.; PEREIRA, V. S. do A.; SOUZA, P. E. de A.; MOREIRA, T. F.; MATIELLO, J. P.; CARVALHO, W. A. Conteúdo: O carrapato bovino desencadeia a diminuição da rentabilidade na pecuária. Animais Bos taurus taurus possuem maior suscetibilidade ao parasitismo do que Bos taurus indicus, refletida por variações imunogenéticas e de intensidade da resposta inflamatória cutânea. Dessa forma, o presente estudo avaliou protótipos de nanossistemas imunomoduladores, de uso veterinário, em fase de desenvolvimento tecnológico pela equipe e sob sigilo de propriedade intelectual, quanto à sua capacidade de interferir no ciclo biológico do carrapato. Bovinos da raça Holandesa foram distribuídos em quatro grupos experimentais (n=6/grupo) e imunizados com: Nanossistema Imunomodulador Biocompatível com direcionamento ativo para Fagócitos (NIBDAF), NIBDAF conjugado com extrato de larva do carrapato bovino (NIBDAF+EL), somente extrato de larva ou solução salina. Em seguida, os animais foram infestados artificialmente com 15.000 larvas/animal. 21 a 23 dias após a infestação, foram coletadas fêmeas ingurgitadas para determinação do peso corporal, peso de postura e taxa de eclosão larval. Resultados demonstram que NIBDAF e NIBDAF+EL reduziram significativamente o peso da postura dos carrapatos, sinalizando uso promissor do nanossistema como alternativa de controle do carrapato bovino. Essa pesquisa possui alinhamento ao Objetivo do Desenvolvimento Sustentável 2 (ODS 2), da ONU (Organização das Nações Unidas), “Erradicação da fome: Acabar com a fome, alcançar a segurança alimentar e melhoria da nutrição e promover a agricultura sustentável”, inserido na Agenda 2030, uma vez que, busca uma solução para um dos maiores problemas sanitários das cadeias produtivas do leite e da carne.
