Special Issue Information

Dear Colleagues,

Metabolic syndrome is a constellation of disturbances including glucose intolerance, central obesity, hypertension, and dyslipidemia present in several forms, depending upon the combination of the different components of the syndrome. The initiation and development of a variety of metabolic syndromes and human diseases accompanies inflammation, which is a major defense of the cells and the body’s adaptation to environmental conditions. More recently, the chronic low-grade inflammatory condition that often accompanies the metabolic syndrome has been implicated as a major factor both in the installation of the metabolic syndrome and its associated pathophysiological consequences. Several scientific studies have suggested that the ingestion of dietary plant extract, containing components such as polyphenol, can protect cells from the excess inflammatory responses and ameliorate metabolic syndrome via regulating the inflammation-related signaling pathways and changing the gut microbiota. However, the detailed mechanisms underlying the role of these plant extracts in the regulation of inflammation, oxidative stress, and microbiota remain largely unknown.

In this Special Issue of Foods, we encourage the submission of manuscripts focused on addressing the roles of plant extracts or phytochemicals in the regulation of inflammation and metabolic syndrome in in vitro or in vivo models, and further exploring the molecular mechanisms underlying their actions and the assessment of the impact of plant extracts or phytochemicals on metabolic syndrome, gut health, and inflammation-related disorders.

We welcome various types of manuscripts, including original research and review articles. All manuscripts should be relevant but not limited to the following specific themes:

  • The effects of polyphenols on metabolic syndrome or inflammation-related intestinal diseases;
  • The underlying mechanisms of the modulation of the intestinal barrier, gut microbiota, and oxidative stress;
  • The crosstalk among inflammation, gut microbiota, and host oxidative stress/metabolism;
  • The development of nutritional strategies to reduce the risks of metabolic syndrome.

The bioactivity of tea polysaccharides (TPs) has been widely reported, but studies to date have focused on green tea. Some human health investigations have implied that black tea may possess potential antidiabetic effects, but less is known about their potential role and related antidiabetic mechanism. The present study was, therefore, conducted to investigate the chemical properties and antidiabetic activity of TPs from black tea. Monosaccharide composition revealed that Alduronic acid (77.8 mol%) considerably predominated in the fraction. TP conformation analysis indicated that three components in TPs were all typical of high-branching structures. Oral administration of TPs could effectively alleviate fasting blood glucose in type 2 diabetes mellitus (T2D) mice, with the values 23.6 ± 1.42, 19.6 ± 2.25, and 16.4 ± 2.07 mmol/L in the 200, 400, and 800 mg/kg·BW groups, respectively. Among these TPs groups, the 800 mg/kg·BW groups significantly decreased by 37.88% when compared with the T2D+water group (p < 0.05). Further studies demonstrated that TP treatment upregulated the expression of p-Akt/p-PI3K (p < 0.001). Additionally, TP treatment significantly promoted glucose transporter protein 2 (GLUT2) translocation in the liver (p < 0.001). These findings suggest that TPs from black tea protect against T2D by activating PI3K/Akt/GLUT2 signaling and might serve as a novel therapeutic candidate for T2D. Full article
