Abstract
The medicinal plant Phyllanthus emblica Linn. has been recognized for its health-beneficial properties and has a long history of cultivation in ancient China and India. However, its effects and main mechanism in high-fat diet (HFD)-induced metabolic syndrome (MetS) have not been revealed yet. According to our findings, emblica fruit powder (EFP) through the freeze-drying process was able to modulate the composition of the intestinal microbiota, with a significant increase in the beneficial bacteria genera Lactobacillus and Turicibacter. In addition, fecal metabolite profiling revealed that 20 metabolites were deferentially expressed, which were mainly organic acids, amino acids, and their derivatives. They are primarily enriched in the biological process of lipid metabolism, including the metabolism process of cholic acid, glycerophospholipid, and α-linoleic acid. Subsequent qPCR testing of the liver tissue suggested that the regulatory effects of EFP in HFD mice may stem from its influence on the expression levels of over 20 key genes involved in host metabolic processes. In conclusion, EFP is able to alleviate the MetS caused by HFD, and this positive impact may be partially through the regulation of the “gut-liver axis.” Consequently, EFP holds potential as a functional food ingredient for the prevention and management of MetS.
期刊介绍:
The Journal of Food Biochemistry publishes fully peer-reviewed original research and review papers on the effects of handling, storage, and processing on the biochemical aspects of food tissues, systems, and bioactive compounds in the diet.
Researchers in food science, food technology, biochemistry, and nutrition, particularly based in academia and industry, will find much of great use and interest in the journal. Coverage includes:
-Biochemistry of postharvest/postmortem and processing problems
-Enzyme chemistry and technology
-Membrane biology and chemistry
-Cell biology
-Biophysics
-Genetic expression
-Pharmacological properties of food ingredients with an emphasis on the content of bioactive ingredients in foods
Examples of topics covered in recently-published papers on two topics of current wide interest, nutraceuticals/functional foods and postharvest/postmortem, include the following:
-Bioactive compounds found in foods, such as chocolate and herbs, as they affect serum cholesterol, diabetes, hypertension, and heart disease
-The mechanism of the ripening process in fruit
-The biogenesis of flavor precursors in meat
-How biochemical changes in farm-raised fish are affecting processing and edible quality
