Kidney Bean Fermented Broth Alleviates Hyperlipidemic by Regulating Serum Metabolites and Gut Microbiota Composition. Nutrients 2022; 14:nu14153202. [PMID: 35956378 PMCID: PMC9370468 DOI: 10.3390/nu14153202] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2022] [Revised: 07/29/2022] [Accepted: 07/30/2022] [Indexed: 11/26/2022] Open
Abstract
Hyperlipidemia with fat accumulation and weight gain causes metabolic diseases and endangers human body health easily which is accompanied by metabolic abnormalities and intestinal flora disorders. In this study, the kidney bean fermented broth (KBF) was used in rats that were fed a high-fat diet to induce hyperlipidemia in order to subsequently analyse the serum metabolomics and gut microbiota modulatoration. The results show that the contents of the total polyphenols and total flavonoids in the KBF were up three and one times, while energy and carbohydrates decreased. In the HFD-induced hyperlipidemic model, body weight, organ weight, and the level of blood lipids (ALT, AST, TG, TC) were lower in rats treated with KBF than in the controls. Metabonomics indicate that there were significant differences in serum metabolomics between the KBF and the HFD. KBF could significantly improve the glycerophospholipids, taurine, and hypotaurine metabolism and amino acid metabolism of hyperlipidemic rats and then improve the symptoms of hypersterol and fat accumulation in rats. The relative abundance of beneficial bacteria increased while pathogenic bacteria decreased after the intervention of KBF. KBF ameliorates dyslipidemia of HFD-induced hyperlipidemic via modulating the blood metabolism and the intestinal microbiota. Collectively, these findings suggest that KBF could be developed as a functional food for anti-hyperlipidemia.

Abstract
The rising prevalence of overweight and obesity is a global concern, increasing the risk of numerous non-communicable diseases and reducing quality of life. A healthy diet and exercise remain the cornerstone treatments for obesity. However, adherence rates can be low and the effectiveness of these interventions is often less than anticipated, due to compensatory changes in other aspects of the energy balance equation. Whilst some alternative weight-loss therapies are available, these strategies are often associated with side effects and are expensive. An alternative or adjunct to traditional weight-loss approaches may be the use of bioactive compounds extracted from food sources, which can be incorporated into habitual diet with a low cost and minimal burden. One product which has attracted attention in this regard is white kidney bean extract (WKBE), which has been suggested to inhibit the enzyme α-amylase, limiting carbohydrate digestion and absorption with small but potentially meaningful attendant beneficial effects on body weight and metabolic health. In this review, drawing evidence from both human and animal studies, we discuss the current evidence around the effects of WKBE on body composition and metabolic health. In addition, we discuss evidence on the safety of this supplement and explore potential directions for future research.

Peptides 2016; 76:30-44. [PMID: 26617077 DOI: 10.1016/j.peptides.2015.11.003] [Citation(s) in RCA: 42] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2015] [Revised: 10/07/2015] [Accepted: 11/19/2015] [Indexed: 01/17/2023]
Abstract
It is well known that endogenous bioactive proteins and peptides play a substantial role in the body's first line of immunological defence, immune-regulation and normal body functioning. Further, the peptides derived from the luminal digestion of proteins are also important for body function. For example, within the peptide database BIOPEP (http://www.uwm.edu.pl/biochemia/index.php/en/biopep) 12 endogenous antimicrobial and 64 angiotensin-I-converting enzyme (ACE-I) inhibitory peptides derived from human milk and plasma proteins are listed. The antimicrobial peptide database (http://aps.unmc.edu/AP/main.php) lists over 111 human host-defence peptides. Several endogenous proteins are secreted in the gut and are subject to the same gastrointestinal digestion processes as food proteins derived from the diet. The human gut endogenous proteins (GEP) include mucins, serum albumin, digestive enzymes, hormones, and proteins from sloughed off epithelial cells and gut microbiota, and numerous other secreted proteins. To date, much work has been carried out regarding the health altering effects of food-derived bioactive peptides but little attention has been paid to the possibility that GEP may also be a source of bioactive peptides. In this review, we discuss the potential of GEP to constitute a gut cryptome from which bioactive peptides such as ACE-I inhibitory, renin inhibitory and antioxidant peptides may be derived.

Abstract
We evaluated the polypeptide profiles, inhibition of human salivary α-amylase activity, and hemagglutination properties of a commercial phaseolamin sample. We also performed an in vivo assay to investigate the effects of a commercial phaseolamin treatment (100, 500, or 1500 mg/kg) over 20 days on the glycemia, body weight, and serum biochemical parameters (total cholesterol, triglycerides, alanine aminotransferase, and aspartate aminotransferase) of nondiabetic and streptozotocin-induced diabetic rats. The in vitro evaluation showed defined protein profiles, low hemagglutination activity, and high α-amylase inhibition. None of the experimental groups treated with phaseolamin or acarbose showed decreases in body weight. Our data demonstrate that phaseolamin inhibits amylase activity in vitro, reduces blood glucose levels, decreases or attenuates some of the renal and hepatic effects of diabetes in streptozotocin-induced rats, and could therefore have therapeutic potential in the treatment or prevention of the complications of diabetes.

Abstract
The objectives of this study were to evaluate the antioxidant capacity of protein hydrolysates of the common bean (Phaseolus vulgaris L.) varieties Negro 8025 and Pinto Durango and determine their effect on the markers of inflammation in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Cell viability was determined and the percentage of viable cells was calculated and concentrations that allowed >80% cell viability were used to determine the markers of inflammation. Alcalase hydrolysates and pepsin-pancreatin hydrolysates showed the highest antioxidant capacity after 80 and 120min of hydrolysis, respectively. Alcalase hydrolysates of the common bean Pinto Durango at 120min inhibited inflammation, with IC50 values of 34.9±0.3, 13.9±0.3, 5.0±0.1 and 3.7±0.2μM, while var. Negro needed 43.6±0.2, 61.3±0.3, 14.2±0.3 and 48.2±0.1μM for the inhibition of cyclooxygenase-2 expression, prostaglandin E2 production, inducible nitric oxide synthase expression and nitric oxide production, respectively. Also, hydrolysates significantly inhibited the transactivation of NF-κB and the nuclear translocation of the NF-κB p65 subunit. In conclusion, hydrolysates from the common bean can be used to combat inflammatory and oxidative-associated diseases.

Abstract
Many believe that excessive intake of refined carbohydrates (CHO) plays a major role in the development of obesity/overweight, type 2 diabetes mellitus and insulin resistance, a collection of events commonly referred to as "diabesity," and have sought natural means to overcome these linked perturbations. As a first approach, planned diets with low portions of refined CHO have become popular. However, these diets do not satisfy everyone; and many are concerned over replacing CHO with more fats. As a second option, addition of soluble fiber to the diet can slow absorption of refined CHO, i.e., lower the glycemic index of foods and overcome or at least ameliorate many of the adverse reactions resulting from increased refined CHO ingestion. Unfortunately, the general public does not favor diets high in fiber content, and various fibers can lead to gastrointestinal problems such as gas and diarrhea. A third choice to favorably influence CHO absorption is to use natural dietary supplements that block or slow CHO absorption in the gastrointestinal tract via inhibiting enzymes necessary for CHO absorption -amylase and alpha-glucosidases. Although a number of natural supplements with anti-amylase activity have been recognized, the most studied and favored one is white kidney bean extract. Animal and human studies clearly show that this agent works in vivo and has clinical utility. This paper reviews many aspects of diabesity and the use of "carb blockers" to prevent and ameliorate the situation. In many respects, carb blockers mimic the beneficial effects of fibers.

Abstract
We studied the effect of dietary free peptides vs. peptides released naturally during digestion on gut endogenous nitrogen (N) flow (ENFL) and amino acid (AA) flow (EAAFL). Semisynthetic diets containing 110 g/kg diet of the same casein, intact (C) or hydrolyzed (HC), were formulated with TiO2 as a dietary marker. Sprague-Dawley rats were fed the diets hourly (0800-1500 h) for 10 min each hour for 7 d. Rats received unlabeled diets for 6 d and 15N-labeled diets on d 7, whereby they were killed and digesta sampled (6 observations per group) along the intestinal tract. EAAFL and ENFL were determined by 15N-isotope dilution (ID) for C or by ID or after centrifugation and ultrafiltration (UF) for HC. Ileal EAAFL and ENFL (ID) were not enhanced with diet HC compared with diet C. The AA compositions (g/16 g N) of ileal ENFL did not differ between rats fed HC and C except for Asp, Phe, Tyr, and Ser, for which contributions were relatively lower (P < 0.05) for rats fed C. Ileal EAAFL and ENFL (HC) were considerably lower (P < 0.05) with ID than with UF, but flows of Gly, Phe, and His were similar. There was no stimulatory effect of dietary peptides from HC on endogenous ileal protein flow compared with C, but the result is tentative given the high degree of dietary N recycled within endogenous protein and which could have occurred at a differential rate between rats fed diets C and HC.

Abstract
The effect of dietary peptides on gut endogenous nitrogen (N) flow (ENFL) and amino acid (AA) flow (EAAFL) was studied. Semisynthetic diets containing enzyme-hydrolyzed casein (HC; 11%) or a free AA mixture devoid of Asp and Ser (A1) or Gly and Ala (A2) were formulated to have similar AA compositions except for the excluded AA and similar dietary electrolyte balances (Na(+)+K(+)-Cl(-)). A protein-free diet (PF) served as a control. Sprague-Dawley rats were given the diets 8 times/d for 10 min each hour for 7 d. Rats were killed and digesta were sampled (6 observations within each group) along the intestinal tract 6 h after the first meal on d 7. EAAFL and ENFL, estimated with reference to the dietary marker TiO(2), were determined directly (PF, A1, and A2) or after centrifugation and ultrafiltration of the digesta (HC). Endogenous flows of Asp and Ser or Gly and Ala did not differ (P > 0.05) in any of the intestinal sections between rats fed PF and A1 or PF and A2, respectively, except in the stomach where Ser flow was greater for rats fed A1. Ileal endogenous flows for most of the AA and for N were higher (P < 0.05) for rats fed the HC diet compared with those for rats fed the PF, A1, or A2 diets, except for Phe, Tyr, Lys, which did not differ among the groups. Ileal EAAFL and ENFL were not influenced by body N balance per se but were affected by the presence in the gut of dietary peptides derived from casein.

Abstract
Rapid gastrointestinal absorption of refined carbohydrates (CHO) is linked to perturbed glucose-insulin metabolism that is, in turn, associated with many chronic health disorders. We assessed the ability of various natural substances, commonly referred to as "CHO blockers," to influence starch and sucrose absorption in vivo in ninety-six rats and two pigs. These natural enzyme inhibitors of amylase/sucrase reportedly lessen breakdown of starches and sucrose in the gastrointestinal tract, limiting their absorption. To estimate absorption, groups of nine SD rats were gavaged with water or water plus rice starch and/or sucrose; and circulating glucose was measured at timed intervals thereafter. For each variation in the protocol a total of at least nine different rats were studied with an equal number of internal controls on three different occasions. The pigs rapidly drank CHO and inhibitors in their drinking water. In rats, glucose elevations above baseline over four hours following rice starch challenge as estimated by area-under-curve (AUC) were 40%, 27%, and 85% of their internal control after ingesting bean extract, hibiscus extract, and l-arabinose respectively in addition to the rice starch. The former two were significantly different from control. L-Arabinose virtually eliminated the rising circulating glucose levels after sucrose challenge, whereas hibiscus and bean extracts were associated with lesser decreases than l-arabinose that were still significantly lower than control. The glucose elevations above baseline over four hours in rats receiving sucrose (AUC) were 51%, 43% and 2% of control for bean extract, hibiscus extract, and L-arabinose, respectively. Evidence for dose-response of bean and hibiscus extracts is reported. Giving the natural substances minus CHO challenge caused no significant changes in circulating glucose concentrations, indicating no major effects on overall metabolism. A formula combining these natural products significantly decreased both starch and sucrose absorption, even when the CHO were given simultaneously. These results support the hypothesis that the enzyme inhibitors examined here at reasonable doses can safely lower the glycemic loads starch and sucrose.
