ABSTRACT

Daylily is a functional food with high nutritional value in China. Datong (DT) in Shanxi Province is one of the four main production areas of daylily. Therefore, Linfen (LF), Lvliang (LL), and Yangquan (YQ) in Shanxi Province have also introduced daylily from DT. However, geographical and climatic conditions and producing patterns cause variations in the daylily quality. In the present study, we found that the nutrient composition of daylilies from different producing areas of Shanxi Province varied. The key environmental factors affecting the nutrition of daylily in different regions were altitude and temperature. The widely targeted metabolomics results showed that 1642 metabolites were found in daylily. The differential metabolites between DT and YQ, LL and LF were 557, 667, and 359, respectively. Notably, 9 metabolic pathways and 59 metabolite markers were associated with daylily from different areas. This study provides a theoretical basis for the quality maintenance and health efficacy research of daylily.

ABSTRACT

Millet and its components have received much extensive attention for their health benefits in mitigating metabolic diseases. Foxtail millet is rich in phytochemicals, including oil. However, the hypoglycemic capacity of foxtail millet oil has yet to be fully investigated. The present study explored the effects of consuming this oil as the lipid extract of foxtail millet (LEFM) on intestinal microbiota composition and metabolic function in diabetic mice. After eight weeks of LEFM supplementation, the blood glucose, insulin resistance index, and lipid accumulation of diabetic mice were significantly decreased. In addition, LEFM feeding modulated gut microbiota composition, reduced the abundance of harmful bacteria (Escherichia-Shigella, Peptococcus, and norank_f_Oscillospiraceae), induced a bloom of probiotics, especially short-chain fatty acid (SCFA)-producing bacteria (Adlercreutzia, Faecalibaculum, and Bifidobacterium), and increased SCFAs concentration. LEFM treatment altered serum metabolite levels, for instance, greatly increasing the levels of l-carnitine and l-glutamine and reducing S-acetyldihydrolipoamide-E and sphingosine. Overall, improvements in gut microbiota and metabolic function were associated with the hypoglycemic potential of LEFM.

ABSTRACT

Millet protein has gained much attention for its beneficial effects in mitigating metabolic diseases. However, most individuals pass through a prediabetic phase before developing full-blown diabetes, and whether millet protein has hypoglycemic effects on prediabetic mice remains unclear. In the present study, heat-treated foxtail millet protein (HMP) supplementation significantly decreased fasting blood glucose and serum insulin levels, alleviated insulin resistance, and improved impaired glucose tolerance in prediabetic mice. In addition, HMP altered the intestinal flora composition, as evidenced by the reduction in the abundance of Dubosiella and Marvinbryantia and the increase in the content of Lactobacillus, Bifidobacterium, and norank_f_Erysipelotrichaceae. Moreover, HMP supplementation dramatically regulated the levels of serum metabolites (i.e., LysoPCs, 11,14,17-eicosatrienoic acid, and sphingosine) and related metabolic pathways, such as sphingolipid metabolism and pantothenate and CoA biosynthesis. In conclusion, the improvement of gut microbiota and serum metabolic profiles was related to the hypoglycemic potential of HMP in prediabetes.

ABSTRACT

Foxtail millet prolamin has been demonstrated to have anti-diabetic effects. In this study, we compared the generation of anti-α-glucosidase peptides derived from prolamins of raw and cooked foxtail millet (PRFM and PCFM). PRFM and PCFM hydrolysates (PRFMH and PCFMH) both exhibited α-glucosidase inhibitory activity. After ultrafiltration according to molecular weight (Mw), the fraction with Mw < 3 kDa in PCFMH (PCFMH<3) showed higher α-glucosidase inhibitory activity than that in PRFMH (PRFMH<3). The composition of α-glucosidase inhibitory peptides identified by de novo sequencing in PCFMH<3 and PRFMH<3 was compared by virtual screening, combining biological activity, net charge, grand average of hydropathicity (GRAVY), and key hydrophobic amino acids (Met, Pro, Phe, and Leu). We found that the proportion of peptides with excellent α-glucosidase binding force in PCFMH<3 was higher than in PRFMH<3. Overall, cooking may positively affect the generation of peptides that perform well in inhibiting α-glucosidase derived from foxtail millet prolamin.

ABSTRACT

Foxtail millet and its components have hypoglycemic effects on mice, but the role of starch and protein in millet in these effects is unclear. The present study investigated the impact of heat-treated foxtail millet starch and protein on type 2 diabetic mice and the underlying mechanisms, including the influence of gut microbiota and serum metabolic profile. In diabetic mice, the consumption of heat-treated foxtail millet starch and protein reduced, respectively, fasting blood glucose 18.52% and 26.33% and insulin levels 12.22% and 15.96%. In addition, heat-treated foxtail millet starch and protein altered the gut microbiota composition, enriched the abundance of probiotics and short-chain fatty acids producing bacteria, reduced harmful bacteria, and increased fecal short-chain fatty acids concentration. Heat-treated foxtail millet protein had greater effects on gut microbiota composition, whereas heat-treated foxtail millet starch had greater effects on metabolic function. The hypoglycemic potential of heat-treated foxtail millet starch and protein was associated with the modulation of both gut microbiota and serum metabolic profile.

ABSTRACT

Interest in polyphenols has grown due to their beneficial effect on diabetes attenuation. Millets are ancient crops that are rich in polyphenols and used for both food and feed. They are grown worldwide and are adapted to production under dry, hot conditions. The polyphenols found in millets have anti-diabetic properties. However, millet is usually consumed after being processed by heating, germination, fermentation, and other processing methods, which may alter polyphenol content and thus affect their anti-diabetic potential. This mini-review profiles the effects of different processing methods on millet polyphenols and how changes in millet polyphenols affect the hypoglycemic effect of millet. Future studies are needed to compare the anti-diabetes potential of millet polyphenols before and after processing and to explore ways to minimize polyphenol losses and thus maintain their hypoglycemic effect in final products.

ABSTRACT

SCOPE: Heat-treated adzuki bean protein hydrolysates (APH) reduce cholesterol in vitro. However, it is unclear if APH have anti-obesity effects in vivo and, if so, the relationship between the effects and the improvement of gut microbiota composition and metabolic function. METHODS AND RESULTS: Four groups of mice are fed either a normal control diet (NCD) or a high-fat diet (HFD) with or without APH for 12 weeks. In HFD-fed mice, APH supplementation significantly alleviate fat accumulation, dyslipidemia, insulin resistance, hepatic steatosis, and inflammation. In addition, APH supplementation regulate gut microbiota composition, reduce the abundance of harmful bacteria (Clostridium_sensu_stricto_1, Romboutsia, Blautia, Mucispirillum, Bilophila, and Peptococcus), enrich Lactobacillus and SCFA-producing bacteria (Lactobacillaceae, Eisenbergiella, Alistipes, Parabacteroides, Tannerellaceae, Eubacterium_nodatum_group, Acetatifactor, Rikenellaceae, and Odoribacter), and increase fecal SCFAs concentration. Importantly, APH supplementation significantly regulate the levels of serum metabolites, especially Lactobacillus-derived metabolites and tryptophan derivatives, which help to alleviate obesity and its complications. CONCLUSION: APH improve gut microbiota composition and metabolic function in mice and may help to prevent and treat obesity and related complications.

ABSTRACT

Adzuki bean consumption has many health benefits, but its effects on obesity and regulating gut microbiota imbalances induced by a high-fat diet (HFD) have not been thoroughly studied. Mice were fed a low-fat diet, a HFD, and a HFD supplemented with 15% adzuki bean (HFD-AB) for 12 weeks. Adzuki bean supplementation significantly reduced obesity, lipid accumulation, and serum lipid and lipopolysaccharide (LPS) levels induced by HFD. It also mitigated liver function damage and hepatic steatosis. In particular, adzuki bean supplementation improved glucose homeostasis by increasing insulin sensitivity. In addition, it significantly reversed HFD-induced gut microbiota imbalances. Adzuki bean significantly reduced the ratio of Firmicutes/Bacteroidetes (F/B); enriched the occurrence of Bifidobacterium, Prevotellaceae, Ruminococcus_1, norank_f_Muribaculaceae, Alloprevotella, Muribaculum, Turicibacter, Lachnospiraceae_NK4A136_group, and Lachnoclostridium; and returned HFD-dependent taxa (Desulfovibrionaceae, Bilophila, Ruminiclostridium_9, Blautia, and Ruminiclostridium) back to normal status. PICRUSt2 analysis showed that the changes in gut microbiota induced by adzuki bean supplementation may be associated with the metabolism of carbohydrates, lipids, sulfur, and cysteine and methionine; and LPS biosynthesis; and valine, leucine, and isoleucine degradation.

ABSTRACT

Recently, there are considerable interests in the influence of prolamins on eating quality of grains. To inquire the potential effect of prolamins on the palatability of foxtail millet, prolamin characteristics under its raw (PR) and post-cooked (PC) state among three typical varieties with high (Zhonggu, ZG), medium (Zhaonong, ZN), and low (Hongmiao, HM) palatability were compared. The distinctive differences in amino acid composition, molecular structure, physicochemical properties were found in PRs and PCs, especially for HM variety. HM-PR recorded the lowest hydrophobic amino acids and surface hydrophobicity while having the superior hydration properties. The lowest denaturation temperature was found in HM-PR, which also had the highest denaturation enthalpy (ΔH). Nevertheless, HM-PR exhibited irregularly spherical protein body with the largest mean diameter. Evidenced by the highest random coil and lower α-helix and ß-sheet content, a less stable secondary structure of HM-PR was found, corresponding to the most intensified disulfide cross-linking and protein aggregations in HM upon cooking. Overall, HM-PR was presumed to greatly affect the hydro-thermal utilization efficiency of starch granules during cooking, given the steric-hindrance effect of prolamins on granules in endosperm. The Present study provided new insights into the role of prolamins on foxtail millet palatability.

ABSTRACT

OBJECTIVE: To explore the effect of mindfulness-based stress reduction (MBSR) therapy combined with intensive education on the effectiveness of the care and the awareness rate in patients with diabetes and arthritis. METHODS: A total of 94 patients with diabetes and arthritis admitted to our hospital were recruited as the study cohort and randomly divided into two groups, with 47 patients in each group. Both groups underwent routine nursing interventions. The control group underwent an eight-week-long intensive education program, while the observation group was additionally cared for with MBSR for 8 weeks. The two groups were assessed using the Symptom Checklist 90 (SCL-90), the Hamilton Anxiety Scale (HAMA-14), the Hamilton Depression Scale (HAMD-17), the Simple Coping Style Questionnaire (SCSQ), the diabetes specificity quality of life scale (DSQL), and their cortisol levels and awareness/satisfaction rates. RESULTS: The SCL-90 scores were lower in both groups after 8 weeks of nursing (P < 0.05), and the scores in the observation group were lower than the scores in the control group (P < 0.05). The observation group exhibited lower HAMA-14, HAMD-17, and negative coping scores (P < 0.05) and higher positive coping scores than the control group (P < 0.05). The DSQL scores and the cortisol levels in the observation group at 2, 4, 6, and 8 weeks after the nursing were lower than they were in the control group (P < 0.05). The satisfaction rate with the nursing methods, the nursing effectiveness, and the awareness rate with regard to regular review, knowledge of pathogenesis, and clinical manifestations in the observation group were higher than they were in the control group (P < 0.05). CONCLUSION: MBSR therapy combined with intensive education can improve patients' symptoms, reduce their anxiety/depression, improve their coping levels, quality of life, and cortisol levels as well as their satisfaction/awareness rates in diabetic patients with arthritis.

ABSTRACT

SCOPE: Millet protein has received much attention due to its beneficial role in alleviating metabolic disease symptoms. This study aims to investigate the role and molecular mechanism of foxtail millet protein isolates, including protein isolates from raw and cooked foxtail millet in alleviating diabetes, including gut microbiota and intracellular signal pathways. METHODS AND RESULTS: Protein isolates from raw and cooked foxtail millet are orally administered to streptozotocin (STZ)-induced diabetic mice for 5 weeks before hypoglycemic effect evaluation. The results show that foxtail millet protein isolates improve glucose intolerance and insulin resistance in diabetic mice. However, only the protein isolate from cooked foxtail millet reverse the weight loss trend and alleviate lipid disorders in diabetic mice. Besides, 16S rRNA sequencing show that both raw and cooked foxtail millet protein isolates altered diabetes-induced gut dysbiosis. In addition, western blotting analysis indicated that the protein isolate from cooked foxtail millet increases the expression levels of glucagon-like peptide-1 receptor (GLP-1R), phosphoinositide 3-kinase (PI3K), and phosphoinositide-protein kinase B (p-AKT)/AKT while the protein isolate from raw foxtail millet downregulates stearoyl-coenzyme A desaturase 1 (SCD1) level. CONCLUSION: Both raw and cooked foxtail millet protein isolates can exert hypoglycemic effects in diabetic mice through rewiring glucose homeostasis, mitigating diabetes-induced gut dysbiosis, and affecting the GLP-1R/PI3K/AKT pathway.

ABSTRACT

Millet proteins have been demonstrated to possess glucose-lowering and lipid metabolic disorder modulation functions against diabetes; however, the molecular mechanisms underlying their anti-diabetic effects remain unclear. The present study aimed to investigate the hypoglycemic effect of prolamin from cooked foxtail millet (PCFM) on type 2 diabetic mice, and explore the gut microbiota and serum metabolic profile changes that are associated with diabetes attenuation by PCFM. Our diabetes model was established using a high-fat diet combined with streptozotocin before PCFM or saline was daily administrated by gavage for 5 weeks. The results showed that PCFM ameliorated glucose metabolism disorders associated with type 2 diabetes. Furthermore, the effects of PCFM administration on gut microbiota and serum metabolome were investigated. 16S rRNA gene sequencing analysis indicated that PCFM alleviated diabetes-related gut microbiota dysbiosis in mice. Additionally, the serum metabolomics analysis revealed that the metabolite levels disturbed by diabetes were partly altered by PCFM. Notably, the decreased D-Glucose level caused by PCFM suggested that its anti-diabetic potential can be associated with the activation of glycolysis and the inhibition of gluconeogenesis, starch and sucrose metabolism and galactose metabolism. In addition, the increased serotonin level caused by PCFM may stimulate insulin secretion by pancreatic ß-cells, which contributed to its hypoglycemic effect. Taken together, our research demonstrated that the modulation of gut microbiota composition and the serum metabolomics profile was associated with the anti-diabetic effect of PCFM.
