Nutrition is one of the most influential environmental factors in both taxonomical shifts in gut microbiota as well as in the development of type 2 diabetes mellitus (T2DM). Emerging evidence has shown that the effects of nutrition on both these parameters is not mutually exclusive and that changes in gut microbiota and related metabolites such as short-chain fatty acids (SCFAs) and branched-chain amino acids (BCAAs) may influence systemic inflammation and signaling pathways that contribute to pathophysiological processes associated with T2DM. With this background, our review highlights the effects of macronutrients, carbohydrates, proteins, and lipids, as well as micronutrients, vitamins, and minerals, on T2DM, specifically through their alterations in gut microbiota and the metabolites they produce. Additionally, we describe the influences of common food groups, which incorporate varying combinations of these macronutrients and micronutrients, on both microbiota and metabolic parameters in the context of diabetes mellitus. Overall, nutrition is one of the first line modifiable therapies in the management of T2DM and a better understanding of the mechanisms by which gut microbiota influence its pathophysiology provides opportunities for optimizing dietary interventions.

Microbial transmission from mother to infant is important for offspring microbiome formation and health. However, it is unclear whether maternal gut inflammation (MGI) during lactation influences mother-to-infant microbial transmission and offspring microbiota and disease susceptibility. In this study, it is found that MGI during lactation altered the gut microbiota of suckling pups by shaping the maternal microbiota in the gut and mammary glands.

This review paper delves into the role of probiotics and food bioactives in influencing gut health and overall well-being, within the context of probiotics and food bioactives, emphasizing their roles in modulating inflammation, gut microbiota, and metabolic health. Probiotics are defined as live microorganisms that confer health benefits to the host, primarily through their impact on the gut microbiome; a complex community of microorganisms crucial for maintaining health. The review aims to elucidate how probiotics, incorporated into both traditional and modern food systems, can enhance gut health and address metabolic disorders.

Purpose: Doxorubicin (Dox) is a classic anthracycline chemotherapy drug with cause cumulative and dose-dependent cardiotoxicity. This study aimed to investigate the potential role and molecular mechanism of phenylacetylglutamine (PAGln), a novel gut microbiota metabolite, in Dox-induced cardiotoxicity (DIC).
Methods: DIC models were established in vivo and in vitro, and a series of experiments were performed to verify the cardioprotective effect of PAGln.

Type 2 diabetes (T2D) is an important risk factor for brain cognitive impairment, but the specific mechanism is still unclear. The imbalance of gut microbiota under pathological conditions (such as an increase in pathogenic bacteria) may be involved in the occurrence of various diseases. The purpose of this study is to investigate the effect of increased abundance of gut Citrobacter rodentium on cognitive function in T2D mice.

Norvaline is a nonproteinogenic amino acid and an important food ingredient supplement for healthy food. In this study, dl-norvaline administration reduced body weight by more than 40% and improved glucose metabolism and energy metabolism in obese mice induced by a high-fat diet (HFD). Combination analysis of microbiome and metabolomics showed that dl-norvaline supplementation regulated gut bacteria structure, such as increasing beneficial bacteria (, , , , , , , and ) and decreasing harmful bacteria (, , , , , and ) and modulated the metabolites involved in arachidonic acid metabolism, thus further promoting short-chain fatty acid production and improving gut barrier, thereby inflammatory responses and oxidative stress were ameliorated.
