Dietary nutrients shape gut microbes and intestinal mucosa via epigenetic modifications

Jianmin Wu, Ying Zhao, Xian Wang, Lingchang Kong, Lee J. Johnston, Lin Lu, Xi Ma

Summary: The imbalance of intestinal microecology can lead to impairment of the intestinal mucosa barrier and function, and further damage the functions of distal organs, resulting in systemic diseases.Intestinal microbiota and intestinal mucosa barrier can be shaped and regulated by nutrients and modes of life, which can help mitigate stress.Research shows that dynamic epigenetic modifications of intestinal tissue play a significant role in mediating the interactions between gut microbes and the gut mucosa barrier.

The role of short-chain fatty acids in immunity, inflammation and metabolism

Yao Yao, Xiaoyu Cai, Weidong Fei, Yiqing Ye, Mengdan Zhao, Caihong Zheng

Summary: Short-chain fatty acids (SCFAs) are important metabolites of gut microbiome and play a vital role in host health. They are key energy sources for colon and ileum cells, regulate intestinal epithelial barrier and defense functions, modulate the function of innate immune cells, regulate the differentiation of T cells and B cells, and also inhibit tumor cell proliferation and promote apoptosis.

Summary: Loss of skeletal muscle mass and function is common in individuals with obesity. The co-existence of excess adiposity and low muscle mass/function, known as sarcopenic obesity (SO), negatively impacts patient outcomes. However, the lack of a universally established definition and diagnostic criteria for SO hampers prevention and treatment efforts.

ZnO Nanostructures in Active Antibacterial Food Packaging: Preparation Methods, Antimicrobial Mechanisms, Safety Issues, Future Prospects, and Challenges

Insoo Kim, Karthika Viswanathan, Gopinath Kasi, Sarinthip Thanakkasaranee, Kambiz Sadeghi, Jongchul Seo

Summary: Packaging of food products is a crucial stage in the food supply chain, and the use of nano-size materials, such as ZnO nanoparticles, can improve packaging performance and extend food shelf-life. This review discusses the application of ZnO nano-size in active packaging of foods, including the crystal structures, morphologies, antimicrobial mechanisms, and packaging applications. The generation of reactive oxygen species is the primary antimicrobial mechanism of ZnO NPs, which can inhibit the growth of fungi and bacteria and reduce cross-contamination risks. The potential health concerns and hazards of ZnO NPs application, such as migration and ingestion, are also elaborated, emphasizing the need for further safety regulations and case studies.

Flavor mystery of Chinese traditional fermented baijiu: The great contribution of ester compounds

Youqiang Xu, Jingrong Zhao, Xiao Liu, Chunsheng Zhang, Zhigang Zhao, Xiuting Li, Baoguo Sun

Summary: Chinese traditional fermented baijiu is a famous alcoholic beverage with a unique flavor profile, mainly due to the contribution of esters, particularly ethyl esters. Various microbial species affect the synthesis of esters through fatty acid and amino acid metabolism, influencing the final taste of baijiu. Understanding the mechanism of baijiu flavor formation is crucial for ensuring reproducible flavor profile.
