Abstract
In this era of pandemics, reducing the risk of lifestyle-related diseases (LRD) by functional foods is of paramount importance. The conventional process of functional food development almost invariably involves in vitro, animal, and human intervention trials, but differences in intestinal environments between humans and experimental animals make it difficult to develop functional foods that are truly effective in humans. Thus, it is necessary to construct a model that simulates the human intestinal environment to evaluate the functionality of any food component before subjecting it to a human intervention trial. In this review, we provide an overview of a model simulating human intestinal microbiota constructed at Kobe University and its use as a tool to identify food components that contribute to the prevention and treatment of LRD.

Estrada-Sierra NA, Gonzalez-Avila M, Urias-Silvas JE, Rincon-Enriquez G, Garcia-Parra MD, Villanueva-Rodriguez SJ. The Effect of Opuntia ficus Mucilage Pectin and Citrus aurantium Extract Added to a Food Matrix on the Gut Microbiota of Lean Humans and Humans with Obesity. Foods 2024; 13:587. [PMID: 38397564 PMCID: PMC10887714 DOI: 10.3390/foods13040587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Revised: 02/02/2024] [Accepted: 02/07/2024] [Indexed: 02/25/2024] Open
Abstract
Experimental studies have provided evidence that physicochemical interactions in the food matrix can modify the biologically beneficial effects of bioactive compounds, including their effect on gut microbiota. This work aimed to evaluate the effect of a food gel matrix with Opuntia ficus cladodes mucilage pectin and Citrus Aurantium extract on the growth of four beneficial gut bacteria obtained from the fecal microbiota of people who are lean or who have obesity after digestion in the upper digestive system. To accomplish this, a base formulation of Opuntia ficus cladodes mucilage with or without C. aurantium extract was submitted to an ex vivo fecal fermentation in an automatic and robotic intestinal system. The changes in the intestinal microbiota were determined by means of plate culture and 16S sequencing, while short-chain fatty acids (SCFA) produced in the colon were determined via gas chromatography. In the presence of the extract in formulation, greater growth of Bifidobacterium spp. (+1.6 Log10 Colonic Forming Unit, UFC) and Lactobacillus spp. (+2 Log10 UFC) in the microbiota of lean people was observed. Only the growth in Salmonella spp. (-1 Log10 UFC) from both microbiota was affected in the presence of the extract, which decreased in the ascending colon. SCFA was mainly produced by the microbiota of people who were lean rather than those who had obesity in the presence of the extract, particularly in the ascending colon. The effect of sour orange extract seems to depend on the origin of the microbiota, whether in people who have obesity (25 mM/L) or are lean (39 mM/L).

Abstract
PURPOSE This randomized crossover trial investigated the effects of Daikenchuto (DKT: TJ-100) on gastrointestinal symptoms of patients after colon and rectosigmoid cancer surgery. METHODS Among patients who had completed surgery for colon cancer, including rectosigmoid cancer, over 6 months ago, 20 who complained of gastrointestinal symptoms were enrolled. Subjects were randomly assigned to two sequences: sequences: A and B. In period 1, sequence A subjects were orally administered DKT, whereas sequence B subjects were untreated for 28 days. After a 5-day interval, in period 2, sequences A and B were reversed. Quality-of-life markers (GSRS and VAS), the Sitzmark transit study, the orocecal transit time (lactulose hydrogen breath test) and Gas volume score were evaluated before and after each period with findings compared between the presence of absence of DKT administration. RESULTS Between sequences, there were no significant differences in clinicopathological characters or any evaluations before randomization. There was no carryover effect in this crossover trial. The administration of DKT significantly ameliorated the GSRS in total, indigestion, and diarrhea, although the planned number of subjects for inclusion in this trial was not reached. CONCLUSIONS DKT may ameliorate subjective symptoms for postoperative patients who complain of gastrointestinal symptoms.

Cancers (Basel) 2022; 14:cancers14225682.

Abstract
Colorectal cancer (CRC) is the second most frequent cause of cancer-related mortality among all types of malignancies. Sedentary lifestyles, obesity, smoking, red and processed meat, low-fiber diets, inflammatory bowel disease, and gut dysbiosis are the most important risk factors associated with CRC pathogenesis. Alterations in gut microbiota are positively correlated with colorectal carcinogenesis, as these can dysregulate the immune response, alter the gut's metabolic profile, modify the molecular processes in colonocytes, and initiate mutagenesis. Changes in the daily diet, and the addition of plant-based nutraceuticals, have the ability to modulate the composition and functionality of the gut microbiota, maintaining gut homeostasis and regulating host immune and inflammatory responses. Spices are one of the fundamental components of the human diet that are used for their bioactive properties (i.e., antimicrobial, antioxidant, and anti-inflammatory effects) and these exert beneficial effects on health, improving digestion and showing anti-inflammatory, immunomodulatory, and glucose- and cholesterol-lowering activities, as well as possessing properties that affect cognition and mood. The anti-inflammatory and immunomodulatory properties of spices could be useful in the prevention of various types of cancers that affect the digestive system. This review is designed to summarize the reciprocal interactions between dietary spices and the gut microbiota, and highlight the impact of dietary spices and their bioactive compounds on colorectal carcinogenesis by targeting the gut microbiota.

Effect of garlic extract on weight loss and gut microbiota composition in obese women: A double-blind randomized controlled trial. Front Nutr 2022; 9:1007506. [PMID: 36352899 PMCID: PMC9638143 DOI: 10.3389/fnut.2022.1007506] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Accepted: 09/29/2022] [Indexed: 11/21/2022] Open
Abstract
Objective From a nutritional perspective, garlic extract could be a prebiotic product, which is useful for obese subjects, and one of its health-promoting underlying mechanisms is modulating gut microbiota composition. In this randomized double-blind clinical trial, the goal was to determine the effect of Allium (garlic extract) on anthropometric indices and gut microbiota composition in obese women following a low-calorie diet. Materials and methods Forty-three obese women were randomly divided into garlic extract (400 mg Allium sativum powder containing 1,100 mcg allicin/tablet) or placebo groups. During the 2 months of the study, each participant took two tablets per day. At the beginning and at the end of the clinical trial, anthropometric measurements were done and blood and fecal samples were collected. We evaluated the gut microbiota composition using quantitative real-time PCR. Results In total, 16 subjects in each group completed the 2-month trial. Allium and placebo groups’ participants had mean ages of 37.8 ± 7.4 and 34.2 ± 6.8 years, respectively (P > 0.05). Baseline body mass index (BMI) was significantly different between groups, subjects in the placebo group had lower BMI compared with the Allium group (P < 0.05). Allium and placebo caused a 1.7% and 2.7% decrease in BMI from the baseline values, respectively (P < 0.01). Fasting insulin level significantly decreased in the both groups (P < 0.01). Level of homeostasis model assessment of insulin resistance (HOMA-IR) has decreased significantly in the Allium group (P = 0.007). The frequency of Akkermansia had decreasing trend while the abundance of Faecalibacterium and Bifidobacterium showed increasing trend in the Allium group. Conclusion In the both groups, a decrease in BMI and other anthropometric indices has been observed. Despite weight loss after following a low-calorie diet and taking Allium, slight changes have been shown in the composition of gut microbiota in obese women. Trial registration This trial was registered in the Iranian Registry of Clinical Trials (IRCT) (code: IRCT090420001825N2).

Abstract
Ginger (Zingiber officinale) is a famous dietary spice rich in bioactive components like gingerols, and it has been used for a long time as food and medicine. Indeed, clinical studies have confirmed the anti-inflammatory and antioxidant properties of ginger. Thus, ginger seems to be an excellent complementary nutritional strategy for non-communicable diseases (NCD) such as obesity, diabetes, cardiovascular disease and chronic kidney disease. This narrative review aims to discuss the possible effects of ginger on the mitigation of common complications such as inflammation, oxidative stress, and gut dysbiosis in NCD.

Abstract
The profile of the human small intestinal microbiota remains to be uncovered primarily due to sampling difficulties. Ileostomy provides the intestinal luminal contents as ileostomy effluents (IE) that offer opportunity for performing extensive analyses of nutrients, gastrointestinal fluids, metabolites, and microbiome. In the present study, we evaluated changes in the microbiome, pH, and bacterial short-chain fatty acids (SCFAs) in IE obtained from patients who had undergone ileostomy following surgical resection of colon cancer and inflammatory bowel disease (IBD). We enrolled 11 patients who varied in the duration of ileostomy from 3 days to >5 years after surgery and had no inflammation in the small intestine. The analyses suggested that IE from patients previously having IBD had less diversity and greater intraday and interday fluctuations, and increased pH and decreased levels of propionic acid and acetic acid than those in IE from patients previously having cancer. Furthermore, correlation analysis suggested a possible effect of the intestinal microbiome on luminal pH, presumably via SCFA production. The present study suggested that inflammation in the colon may induce long-term dysbiosis in the small intestine even after removal of diseased parts of the colon. Moreover, pharmaceutical-grade Japanese traditional medicine daikenchuto (TU-100) was found to have beneficial effects on postoperative bowel dysfunction and the human small intestinal microbiota. Taken together, these results suggest the necessity of a direct remedy for dysbiosis and the treatment of gastrointestinal lesions to achieve favorable outcomes for chronic gastrointestinal disorders.

Abstract
Vancomycin-resistant enterococci (VRE) are prominent causes of nosocomial infections. Japanese traditional (Kampo) medicine promotes intestinal immunity and protects against bacterial infections. We assessed potential differences in the clinical course of VRE-positive patients, based on their characteristics and treatment with Kampo medicines. This retrospective observational study collected data from VRE-positive patients from August 2018 to July 2019 at a tertiary-care hospital in Japan. The data of 122 consecutive VRE-positive inpatients were analyzed. Sixty-nine patients were treated with probiotics, among whom, 18 were further treated with Kampo medicines. Twenty-six of the 122 patients subsequently died. In univariate analyses, subsequent VRE negative conversion significantly reduced the mortality of VRE-detected patients (p = .0003). Administration of probiotics (p = .0065) and Kampo medicines with probiotics (p = .0002), especially of the Kampo medicine hochuekkito (p = .0014), and a higher serum albumin level positively contributed to the subsequent VRE negative conversion. Multivariate analyses demonstrated that Kampo medicines and body mass index contributed to VRE negative conversion. Hochuekkito shortened the time needed for VRE negative conversion (p = 0.0485). Administration of Kampo medicines, especially of hochuekkito, in addition to probiotics in VRE patients may promote VRE negative conversion.
