With heightened awareness of cardiovascular health and obesity-particularly visceral adiposity-contemporary consumers prioritize dietary lipid quality and quantity. Substituting triacylglycerol (TAG)-based fat sources with diacylglycerol (DAG)-based sources in meat products without compromising the sensory and technological properties can fulfill consumers' demand for healthier meat products. This review delineates the metabolic pathway distinctions between DAGs and TAGs, summarizes the health benefits of DAGs, and documents their synthesis methodologies. Furthermore, it contrasts animal-derived and plant-derived DAGs while examining recent advances in plant-derived DAG emulsions. Building on this foundation, emerging research on the interaction between DAGs and myofibrillar proteins (MPs) positions them as promising fat replacers in meat products, warranting further exploration for effective quality preservation. Application prospects and implementation barriers for DAGs in emulsified meat systems are also examined. Ultimately, this comprehensive analysis offers valuable insights and guidance for developing healthier meat products and advancing the application of DAGs in the food industry.

Post-harvest diseases pose a considerable threat to food safety and quality, and there is an urgent need for strong strategies to prevent and control them. In order to manage postharvest diseases of fruits and vegetables more efficiently, this review first describes various biocontrol agents (BCAs), including bacterial, fungal, and viral entities, and their basic principles in biocontrol. It then discusses the role of nontraditional chemical approaches, such as chemoinducers, plant extracts, essential oils, microbial metabolites, volatile compounds, and nanotechnology-based approaches, in postharvest diseases of fruits and vegetables. In addition, how nontraditional chemical methods can be utilized to enhance the effectiveness of BCAs is highlighted. The combination of nontraditional chemical methods and BCAs provides an innovative and effective strategy for preventing and controlling postharvest diseases. By utilizing the synergistic effects of various BCAs and nontraditional chemical methods, researchers have made significant progress in disease management. Notably, nanotechnology offers promising new avenues for the preparation and delivery of BCAs. Prospects for this research include the development of complex BCAs, international collaboration in the field of sustainable agriculture, and addressing regulatory challenges.

Research and clinical experience in nutrition have emphasized the merits of some dietary patterns, e.g., the Mediterranean diet, to obtain health-related benefits. This has also been the case of specific foods such as yogurt which has been tested using different approaches and under various conditions. As described in this paper, there is a quasi-consensus among population studies about the protective relationship of regular yogurt consumption with incidence of overweight and type 2 diabetes. This is concordant with laboratory-based experimentation and clinical trials showing that yogurt consumption induces favorable effects on many key components of metabolic homeostasis and energy balance. The benefits of yogurt consumption also seem to be partly explained by its status of fermented food which involves the influence of yogurt on the gut microbiota and the reciprocal role of some bacterial-derived molecules on metabolic regulation. In clinical nutrition, novel education approaches benefit from the versatility of yogurt and its high nutrient density to promote healthy eating behaviors and habits as well as cardiometabolic benefits. In summary, yogurt, especially plain yogurt, should be part of healthy eating habits because of its high nutritional value, its flexible food matrix, its beneficial bacterial components, and its versatility under usual feeding conditions.

Hyperlipidemia is a prevalent metabolic disorder that can lead to other illnesses. Natural products in food, such as active peptides, can help alleviate hyperlipidemia. This study seeks to elucidate the mechanism through which food-derived active peptides (FDAPs) mitigate hyperlipidemia. Through comprehensive literature analysis, we estimated the efficacy and mechanism of FDAPs in reducing blood lipid levels. The results indicate that the structure-activity relationship (SAP) of FDAPs, the ability to regulate intestinal flora, and the regulation of relevant gene expression serve as the primary mechanisms. We leverage bioinformatics methods to analyze the lipid-lowering mechanism of FDAPs. By utilizing the OMIM database, GeneCard database, and TTD database, we identified the differential expressed genes (DEGs) that intersect with FDAPs, linked to hyperlipidemia. String, GO, and KEGG analysis reveal the further mechanism. Furthermore, we screened out the 22 molecular targets. String, GO, and KEGG analysis revealed that FDAPs likely achieve lipid reduction by regulating the expression of HMGCR, CYP7A1, and FAS. The strong correlation between lipid reduction by FDAPs and metabolic pathways, PPAR signaling pathway, and alcoholic liver disease provides valuable insights for the development of novel drugs.
