Special Issue Information

Dear Colleagues,

Numerous epidemiological, clinical, and experimental studies have reported that the physiological activities of dietary functional factors are closely related to the prevention of chronic non-communicable diseases (NCDs) and the promotion of human health. Therefore, it is beneficial to the development of precise nutrition and personalized functional foods by revealing the metabolic mechanism of functional factors during dietary intervention, which has been regarded as a key point in the field of food nutrition and health.

Non-targeted analysis based on modern omics technology, such as proteomics and metabolomics, helps to establish the correlation between the health benefits of functional food and the physiological activities of its bioactive components, and further explore biomarkers after dietary intake. Meanwhile, based on the analysis of the metabolic mechanism of dietary functional factors, the information of endogenous metabolites, metabolic pathways and metabolic networks, etc., will be conductive to elucidate the association between dietary nutrition and health, and deepen our understanding of the efficacy of dietary interventions in disease prevention and human health promotion.

This Special Issue of Metabolites, “Physiological Activity and Metabolic Mechanism of Dietary Functional Factors”, will publish reviews and original articles covering the latest developments of the physiological activities, metabolic process, typical metabolites and metabolic mechanism of dietary functional factors, and the connections between functional factors, including their metabolites and human health. Furthermore, innovative methods and techniques used to analyze, identify, and reveal the metabolic mechanism of dietary functional factors will be welcome.

To evaluate the value of Cirsium japonicum (CJ; thistle) as a material for functional foods, we studied the functional composition of cultivated CJ and the in vitro and in vivo antioxidant activity of the functional substance. The detected phenolics in farmed CJ were chlorogenic acid (CA), linarin (LIN), and pectolinarin (PLIN) by HPLC analysis. As a result of the antioxidant activity of CJ and its phenolics by DPPH and ABTS method, CA had shown the greatest antioxidant activity. We employed Caenorhabditis elegans to validate that in vitro effects of CA are shown in vivo. CA delayed reduction in pumping rate and progeny production during aging of C. elegans. Under both normal and oxidative stress conditions, CA reduced the production of reactive oxygen species (ROS) in worms and increased their lifespan. In particular, CA showed the reducing effect of ROS accumulation due to aging in aged worms (8 days old). To gain insight into the mechanism, we used skn-1/Nrf2 and daf-16/FOXO transformed worms. The CA effects (on catalase activity and lifespan extension) in the wild-type (WT) decreased in skn-1 and daf-16 mutants. In particular, CA strongly relied on daf-16 under mild oxidative condition and skn-1 under overall (from mild to strong) oxidative stress to reduce ROS and extend healthspan. Thus, we conclude that CA, a key bioactive phenolic of CJ, reduces ROS production and ultimately extends healthspan, and this effect is the result of actions of daf-16 or skn-1 at different stages depending on the degree of oxidation or aging. Our results suggest that CJ containing CA can be used as an antiaging material due to its antioxidant properties. Full article

Barley bran has potential bioactivities due to its high content of polyphenols and dietary fiber, etc. Fermentation has been considered as an effective way to promote the functional activity of food raw materials. In this study, polysaccharides from barley bran extract fermented by Lactiplantibacillus plantarum dy-1 (FBBE-PS) were analyzed, and its effects on lipid accumulation and oxidative stress in high-fat HepG2 cells induced by sodium oleate were evaluated. The results showed that the molecular weight decreased and monosaccharide composition of polysaccharides changed significantly after fermentation. In addition, 50 μg/mL FBBE-PS could reduce the triglyceride (TG) content and reaction oxygen species (ROS) level in high-fat HepG2 cells by 21.62% and 30.01%, respectively, while increasing the activities of superoxide dismutase (SOD) and catalase (CAT) represented by 64.87% and 22.93%, respectively. RT-qPCR analysis revealed that FBBE-PS could up-regulate the lipid metabolism-related genes such as ppar-α, acox-1 and cpt-1α, and oxidation-related genes such as nrf2, ho-1, nqo-1, sod1, cat, etc. The metabolomics analysis indicated that FBBE-PS could alleviate lipid deposition by inhibiting the biosynthesis of unsaturated fatty acids, which is consistent with the downregulation of scd-1 expression. It is demonstrated that fermentation can alter the properties and physiological activities of polysaccharides in barley bran, and FBBE-PS exhibited an alleviating effect on lipid deposition and oxidative stress in high-fat cells.
