Abstract
Soy sauce (SS) is a traditional fermented seasoning. Although fermented foods have diverse health beneficial effects, SS intake has been discouraged because of its high salt level. This study was designed to evaluate the antiobesity outcomes of SS and the potential involvement of salt content in SS by adding a high-salt group. Sprague-Dawley rats were randomly assigned into four groups: normal diet (ND, 10% fat of total kcal), high-fat diet (HD, 60% fat of total kcal), HD with salt water (HDSW, NaCl = 8%), and HD with SS (HDSS, NaCl = 8%). SS significantly decreased HD-induced body weight gain and lipogenic gene expression without affecting food consumption. Moreover, SS also reduced hepatic injury and lipid accumulation, and also improved hyperlipidemia. Furthermore, SS decreased the mRNA levels related to obesity-derived inflammatory responses, while HDSW did not change the levels of those markers. These observations indicate that SS ameliorates obesity in HD-fed obese rats by attenuating dyslipidemia. Moreover, SS might also have an anti-inflammatory effect in HD-induced obesity, which requires further investigation. Most importantly, SS offers these beneficial effects regardless of its high salt content, implying that different dietary salt sources lead to the distinct health outcomes. In conclusion, the findings of this study improve the understanding of the functional effect of SS.

Fermented Foods of Korea and Their Functionalities. FERMENTATION-BASEL 2022. [DOI: 10.3390/fermentation8110645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/17/2022]
Abstract
Fermented foods are loved and enjoyed worldwide and are part of a tradition in several regions of the world. Koreans have traditionally had a healthy diet since people in this region have followed a fermented-foods diet for at least 5000 years. Fermented-product footprints are evolving beyond boundaries and taking the lead in the world of food. Fermented foods, such as jang (fermented soybean products), kimchi (fermented vegetables), jeotgal (fermented fish), and vinegar (liquor with grain and fruit fermentation), are prominent fermented foods in the Korean culture. These four major fermented foods have been passed down through the generations and define Korean cuisine. However, scientific advancements in the fermentation process have increased productivity rates and facilitated global exports. Recently, Korean kimchi and jang have garnered significant attention due to their nutritional and health-beneficial properties. The health benefits of various Korean fermented foods have been consistently supported by both preclinical and clinical research. Korean fermented foods effectively reduce the risk of cardiovascular and chronic metabolic diseases, such as immune regulation, memory improvement, obesity, diabetes, and high blood pressure. Additionally, kimchi is known to prevent and improve multiple metabolic diseases, including irritable bowel syndrome (IBS), and improve beneficial intestinal bacteria. These functional health benefits may reflect the synergistic effect between raw materials and various physiologically active substances produced during fermentation. Thus, fermented foods all over the world not only enrich our dining table with taste, aroma, and nutrition, but also the microorganisms involved in fermentation and metabolites of various fermentations have a profound effect on human health. This article describes the production and physiological functions of Korean fermented foods, which are anticipated to play a significant role in the wellness of the world’s population in the coming decades.

Abstract
After thousands of years of evolution and development, traditional fermented soybean foods, with their unique charm, have gained a stable place in the global market. With the explosive development of modern biological technologies, some traditional fermented soybean foods that possess health-promoting benefits are gradually appearing. Physiologically active substances in fermented soybean foods have received extensive attention in recent decades. This review addresses the potential health benefits of several representative fermented soybean foods, as well as the action mechanism and influencing factors of their functional components. Phenolic compounds, low-molecular-weight peptides, melanoidins, furanones and 3-hydroxyanthranilic acid are the antioxidative components predominantly found in fermented soybean foods. Angiotensin I-converting enzyme inhibitory peptides and γ-aminobutyric acid isolated from fermented soy foods provide potential selectivity for hypertension therapy. The potential anti-inflammatory bioactive components in fermented soybean foods include γ-linolenic acid, butyric acid, soy sauce polysaccharides, 2S albumin and isoflavone glycones. Deoxynojirimycin, genistein, and betaine possess high activity against α-glucosidase. Additionally, fermented soybean foods contain neuroprotective constituents, including indole alkaloids, nattokinase, arbutin, and isoflavone vitamin B12. The anticancer activities of fermented soybean foods are associated with surfactin, isolavone, furanones, trypsin inhibitors, and 3-hydroxyanthranilic acid. Nattokinase is highly correlated with antioxidant activity. And a high level of menaquinones-7 is linked to protection against neurodegenerative diseases. Sufficiently recognizing and exploiting the health benefits and functional components of traditional fermented soybean foods could provide a new strategy in the development of the food fermentation industry.

Abstract
Fermented soy foods (FSF) are gaining significant attention due to promising health benefits. In recent years, FSF are being studied extensively due to the presence of diverse functional ingredients including active isoflavones and peptides along with essential micronutrients. The process of fermentation is responsible for the enrichment of various bioactive principles in soy-based fermented foods and exclusion of some anti-nutrient factors which are found predominantly in raw soybeans. Emerging evidence suggests that FSF possess immense therapeutic potential against inflammation and associated pathological complications. Extracts prepared from various FSF (e.g. fermented soy paste, milk, and sauce) were found to exert promising anti-inflammatory effects in numerous in vitro and in vivo settings. Moreover, clinical findings highlighted an inverse relationship between consumption of FSF and the prevalence of chronic inflammatory disorders among the communities which habitually consume fermented soy products. Molecular mechanisms underlying the anti-inflammatory role of FSF have been delineated in many literatures which collectively suggest that FSF extracts have regulatory actions over the expression and/or activity of several proinflammatory cytokines, inflammatory mediators, oxidative stress markers, and some other factors involved in the inflammatory pathways. The present review discusses the anti-inflammatory effects of FSF with mechanistic insights based upon the available findings from cell culture, preclinical, and clinical investigations.

Abstract
Normal gut flora plays various beneficial roles for the human body, including the protection against inflammatory states and mucosal viral infections. It also influences the immune system of the body. The metabolites produced by the gut bacteria control local and other systemic organs' immune functions like the lungs and brain, playing a role in their response to acute and chronic illnesses. Probiotics have shown beneficial effects on lung health. On the contrary, dysbiosis is associated with several diseases, including asthma, chronic bronchitis, emphysema, allergies, and other acute viral infections. By altering the diet of patients with respiratory diseases like patients with chronic obstructive pulmonary diseases (COPD), we may be able to mitigate their conditions. This literature review aims to discuss the mechanisms altering the gastrointestinal flora, the pathophysiology of gut and lung axis, the role of diet in gut microbe health, and the association of COPD with gut dysbiosis and peptic ulcer disease (PUD). We have extracted the data from PubMed and Google Scholar, consisting of review articles, case-control studies, and animal studies. The studies showed an association between gut microbes and different lung diseases. It is found that gut dysbiosis not only disrupts intestinal immunity but may also facilitate the development of COPD. Present studies also show an increased seroprevalence of Helicobacter pylori in patients with COPD. The strategies that can improve lung functions, especially in COPD patients, include prebiotics and probiotic supplementation to a diet more balanced than the current average American diet.

Abstract
Over the course of the reproductive life span, it is common for women to experience one or more of the most common gynecologic conditions, including sexual dysfunction, polycystic ovary syndrome, fibroids, endometriosis, and infertility. Although current management guidelines often turn to the established pharmaceutical approaches for each of these diagnoses, the scientific literature also supports an evidence-based approach rooted in the paradigm of food as medicine. Achieving healthy dietary patterns is a core goal of lifestyle medicine, and a plant-forward approach akin to the Mediterranean diet holds great promise for improving many chronic gynecologic diseases. Furthermore, creating an optimal preconception environment from a nutritional standpoint may facilitate epigenetic signaling, thus improving the health of future generations. This state-of-the-art review explores the literature connecting diet with sexual and reproductive health in premenopausal women.

Abstract
Cheonggukjang (CGJ, fermented soybean paste), a traditional Korean fermented dish, has recently emerged as a functional food that improves blood circulation and intestinal regulation. Considering that excessive consumption of refined salt is associated with increased incidence of gastric cancer, high blood pressure, and stroke in Koreans, consuming CGJ may be desirable, as it can be made without salt, unlike other pastes. Soybeans in CGJ are fermented by Bacillus strains (B. subtilis or B. licheniformis), Lactobacillus spp., Leuconostoc spp., and Enterococcus faecium, which weaken the activity of putrefactive bacteria in the intestines, act as antibacterial agents against pathogens, and facilitate the excretion of harmful substances. Studies on CGJ have either focused on improving product quality or evaluating the bioactive substances contained in CGJ. The fermentation process of CGJ results in the production of enzymes and various physiologically active substances that are not found in raw soybeans, including dietary fiber, phospholipids, isoflavones (e.g., genistein and daidzein), phenolic acids, saponins, trypsin inhibitors, and phytic acids. These components prevent atherosclerosis, oxidative stress-mediated heart disease and inflammation, obesity, diabetes, senile dementia, cancer (e.g., breast and lung), and osteoporosis. They have also been shown to have thrombolytic, blood pressure-lowering, lipid-lowering, antimutagenic, immunostimulatory, anti-allergic, antibacterial, anti-atopic dermatitis, anti-androgenetic alopecia, and anti-asthmatic activities, as well as skin improvement properties. In this review, we examined the physiological activities of CGJ and confirmed its potential as a functional food.

Abstract
Fermented plant foods are gaining wide interest worldwide as healthy foods due to their unique sensory features and their health-promoting potentials, such as antiobesity, antidiabetic, antihypertensive, and anticarcinogenic activities. Many fermented foods are a rich source of nutrients, phytochemicals, bioactive compounds, and probiotic microbes. The excellent biological activities of these functional foods, such as anti-inflammatory and immunomodulatory functions, are widely attributable to their high antioxidant content and lactic acid-producing bacteria (LAB). LAB contribute to the maintenance of a healthy gut microbiota composition and improvement of local and systemic immunity. Besides, antioxidant compounds are involved in several functional properties of fermented plant products by neutralizing free radicals, regulating antioxidant enzyme activities, reducing oxidative stress, ameliorating inflammatory responses, and enhancing immune system performance. Therefore, these products may protect against chronic inflammatory diseases, which are known as the leading cause of mortality worldwide. Given that a large body of evidence supports the role of fermented plant foods in health promotion and disease prevention, we aim to discuss the potential anti-inflammatory and immunomodulatory properties of selected fermented plant foods, including berries, cabbage, and soybean products, and their effects on gut microbiota.

Fermented mulberry (Morus alba) leaves suppress high fat diet-induced hepatic steatosis through amelioration of the inflammatory response and autophagy pathway. BMC Complement Med Ther 2020; 20:283. [PMID: 32948162 PMCID: PMC7501671 DOI: 10.1186/s12906-020-03076-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Accepted: 09/08/2020] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND A novel extract of mulberry leaves fermented with Cordyceps militaris (EMfC) is reported to exert anti-obesity activity, although their molecular mechanism during hepatic steatosis has not verified. METHODS To investigate the role of inflammation and autophagy during the anti-hepatic steatosis effects of EMfC, we measured alterations in the key parameters for inflammatory response and autophagy pathway in liver tissues of the high fat diet (HFD) treated C57BL/6N mice after exposure to EMfC for 12 weeks. RESULTS Significant anti-hepatic steatosis effects, including decreased number of lipid droplets and expression of Klf2 mRNA, were detected in the liver of the HFD + EMfC treated group. The levels of mast cell infiltration, expression of two inflammatory mediators (iNOS and COX-2), and the MAPK signaling pathway were remarkably decreased in the liver of HFD + EMfC treated group as compared to the HFD + Vehicle treated group. Furthermore, a similar inhibitory effect was measured for the expression levels of pro-inflammatory cytokines, including IL-1β, IL-6, TNF-α and NF-κB. The expression level of members in the AKT/mTOR signaling pathway (a central regulator in autophagy) was recovered after treatment with EMfC, and autophagy-related proteins (Beclin and LC3-II) were remarkably decreased in the HFD + EMfC treated group compared to the HFD + Vehicle treated group. Moreover, the HFD + EMfC treated group showed decreased transcript levels of autophagy-regulated genes including Atg4b, Atg5, Atg7 and Atg12. CONCLUSIONS Taken together, findings of the present study provide novel evidences that the anti-hepatic steatosis of EMfC is tightly linked to the regulation of the inflammatory response and autophagy pathway in the liver tissue of HFD-induced obesity mice.

Abstract
Background Tempeh is a widely known fermented soybean that contains elevated level of bioactive contents. Our previous study has shown that anaerobic fermented Nutrient Enriched Soybean Tempeh (NESTE) with increase amino acid and antioxidant levels possessed better hepatoprotective effect than raw soybean. Methods In this study, the anti-inflammatory effect of the NESTE aqueous extract and raw soybean aqueous extract (SBE) were evaluated by quantifying the inhibition of IL-1β, TNF-α and nitric oxide (NO) secretion in LPS treated RAW 264.7 cell in vitro. On the other hand, in vivo oral acute toxicity effect of the extract was tested on mice at the dose of 5000 mg/kg body weight. In vivo oral analgesic effect of both aqueous extracts at 200 and 1000 mg/kg body weight was evaluated by the hot plate test. Results In the in vitro anti-inflammatory study, 5 mg/mL NESTE was able to inhibit 25.50 ± 2.20%, 35.88 ± 3.20% and 28.50 ± 3.50% of NO, IL-1β and TNF-α production in LPS treated RAW 264.7 cells without inducing cytotoxic effect on the cells. However, this effect was lower than 4 μg/mL of curcumin, which inhibited NO, IL-1β and TNF-α production by 89.50 ± 5.00%, 78.80 ± 6.20% and 87.30 ± 4.00%, respectively. In addition, 1.5 to 2.5-fold increase of latency period up to 120 min for mice in the hot plate test was achieved by 1000 mg/kg NESTE. The analgesic effect of NESTE was better than 400 mg/kg of acetyl salicylic acid, which only increased ~ 1.7-fold of latency period up to 90 min. Moreover, NESTE did not show acute toxicity (no LD50) up to 5000 mg/kg body weight. Conclusion NESTE is a nutritious food ingredient with potential anti-inflammatory and analgesic effects.

Abstract
Biological activities of soybean saponins are dependent on their metabolism by gut microbiota, which generate absorbable bioactive metabolites. Therefore, to enhance the pharmacological effect of soybean, we fermented defatted soybean powder (SP) with Lactobacillus pentosus var. plantarum C29 and measured its protective effect against scopolamine-induced memory impairment in mice using the passive avoidance, Y-maze and Morris water maze tasks. Fermentation increased soyasapogenol B, genistein and daidzein content of soybean and enhanced the protective effect of soybean against scopolamine-induced memory impairment. Additionally, compared with the exthanol extract of soybean, fermented SP (FSP) increased the expression of brain-derived neurotrophic factor (BDNF) in the hippocampi of scopolamine-treated mice. Furthermore, FSP inhibited acetylcholinesterase (AChE) activity in vitro and ex vivo. These findings suggest that C29 fermentation might increase the ameliorating effect of soybean against memory impairments by inhibiting AChE activity and increasing BDNF expression.

Abstract
AIMS This study aimed to investigate the potential of Bacillus methylotrophicus as a probiotic. METHODS AND RESULTS A Bacillus isolate designated strain C14 was isolated from Korean traditional fermented soybean paste (doenjang). The strain was identified, and its physiological and biochemical properties were characterized. The gastrointestinal tolerance and immunomodulatory function of strain C14 were also investigated. Strain C14 was identified as B. methylotrophicus by analysis of its biochemical properties using the API 50CHB system and by phylogenetic analysis of the 16S rDNA sequence. Strain C14 showed >80% and >75% of survival for artificial gastric juices (pH 2.5 and 1% pepsin) and 0.5% (w/v) bile salt, respectively. Heat-killed B. methylotrophicus C14 inhibited the adhesion of various pathogens and enhanced the adhesion of probiotic bacteria to Caco-2 cells. The heat-killed cells also induced high levels of immune cell proliferation compared with the control and stimulated interleukin-6 and tumour necrosis factor-α production in mouse macrophages. CONCLUSIONS Bacillus methylotrophicus C14 could be used as a probiotic. SIGNIFICANCE AND IMPACT OF THE STUDY Recently identified B. methylotrophicus is a new potential probiotic with high gastrointestinal tolerance.

Abstract
Sasang constitutional medicine is a major branch of Korean traditional oriental medicine. Constitutions of Sasang medicine are classified into Taeyangin, Taeumin, Soyangin, and Soumin. We investigated immunostimulatory activities of fermented soybean product (FSP) extracts and their major bioactive compounds, isoflavone glycosides in primary immune cells isolated from the blood of Soyangin, Taeumin, and Soeumin volunteers. Results showed that the cell proliferation, nitrite, tumor necrosis factor (TNF)-α mRNA, interleukin (IL)-6 mRNA, inducible nitric oxide synthase (iNOS) mRNA, cyclooxygenase-2 (COX-2) mRNA, TNF-α protein, and IL-6 protein production of immune cells treated with a 70% ethanol Doenjang extract (DJ), a 70% ethanol Kochujang extract (KCJ), and a 70% ethanol Cheonggukjang extract (CGJ), respectively, were significantly increased, and its immunostimulatory activities by both DJ and CGJ was higher than that of KCJ in primary immune cells isolated from the blood of Soyangin volunteers. However, the cell proliferation, nitrite, TNF-α mRNA, IL-6 mRNA, iNOS mRNA, COX-2 mRNA, TNF-α protein, and IL-6 protein production by both KCJ and CGJ was higher than that of DJ in primary immune cells isolated from the blood of Taeumin and Soeumin volunteers. The major bioactive compounds, isoflavone-glycosides, in FSP were daidzin, glycitin, and genistin. Daidzin, glycitin, and genistin were used to treat primary immune cells in the same condition, the cell proliferation; iNOS mRNA expression and nitrite concentration of daidzin, glycitin, or genistin-treated immune cells isolated from the blood of Soyangin volunteers was higher than that of Taeumin and Soeumin volunteers. The effect of DJ and isoflavone glycosides on immunostimulatory activities showed similar trends.

Abstract
Cheonggukjang (CKJ) is a fermented soybean product that exhibits diverse biological and pharmacological activities, including anti-obesity, anti-diabetic, and anti-inflammatory effects on human chronic diseases. In this study, the effects of the aqueous extract of CKJ containing a high concentration of GABA on atopic dermatitis (AD) were quantified using the luciferase reporter system in IL-4/Luc/CNS-1 transgenic (Tg) mice. Alterations of the luciferase signal and phenotypes of AD were quantified in the IL-4/Luc/CNS-1 Tg mice co-treated with phthalic anhydride (PA) and CKJ for 4 weeks using the IVIS imaging system. A strong luciferase signal was detected in the abdominal region of IL-4/Luc/CNS-1 Tg mice treated with PA alone. However, this signal was significantly reduced in IL-4/Luc/CNS-1 Tg mice co-treated with PA and CKJ. The thymus showed the greatest decrease in luciferase following CKJ treatment, but the level increased after PA treatment. Furthermore, the CKJ-treated group showed improvement of common allergic responses including decreased ear thickness, dermis thickness, auricular lymph node (ALN) weight and infiltrating mast cells. However, IgE concentration and epidermis thickness were maintained a constant level. These results indicated that the luciferase signal may successfully reflect the therapeutic effects of CKJ in IL-4/Luc/CNS-1 Tg mice. The results also suggested that CKJ may be considered an effective substance for the treatment of AD.

Abstract
Inflammation plays a crucial role in the pathogenesis of obesity. Purple sweet potato color (PSPC) has potential anti-inflammation efficacy. We evaluated the effect of PSPC on kidney injury induced by high fat diet (HFD) and explored the mechanism underlying these effects. The results showed that PSPC (700 mg/kg per day) reduced body weight, ratio of urine albumin to creatinine, inflammatory cell infiltration, and Collagen IV accumulation in mice fed an HFD (60% fat food) for 20 weeks. PSPC significantly reduced the expression level of kidney NLRP3 inflammasome including NLRP3 and ASC and Caspase-1, and resulted in decline of IL-1β. Moreover, PSPC inhibited the activation of I kappa B kinase β (IKKβ) and the nuclear translocation of nuclear factor kappa beta (NF-κB). Additionally, PSPC decreased the expression level of oxidative stress-associated AGE receptor (RAGE) and thioredoxin interacting protein (TXNIP) in the upstream of NLRP3 inflammasome. These data imply that the beneficial effects of PSPC on HFD-induced kidney dysfunction and damage are mediated through NLRP3 signaling pathways, suggesting a potential target for the prevention of obesity.

Abstract
Doenjang has been reported to exhibit antioxidant, fibrinolytic, antimutagenic, anticancer, and antiobesity effects. In our preliminary study, doenjang decreased fecal lipopolysaccharide (LPS) levels in mice. Therefore, we investigated the effect of doenjang on the composition of gut microbiota in mice. Treatment with doenjang significantly increased the number of bifidobacteria cultured in BL media, compared with mice not treated with doenjang. However, doenjang decreased the number of Enterobacteriaceae cultured in DHL media. Doenjang significantly suppressed the β-glucuronidase activity, but did not influence α-/β-glucosaminidase and α-/β-glucosidase activities. When gut microbiota in mice treated with or without doenjang was analyzed by pyrosequencing, doenjang induced a significant modulation of the populations of the dominant gut microbiota. At the phylum level, doenjang treatment resulted in a significant decrease of Firmicutes and an increase of Bacteroidetes, which led to a decrease in the Firmicutes to Bacteroidetes ratio in gut microbiota. At the family level, the number of Ruminococcaceae and Lachnospiraceae were significantly decreased, while the number of Odoribacter_f was increased in doenjang-treated mice. Of colonic tight junction proteins, occludin, ZO-1, and claudin-1 in mice, occludin alone was significantly increased by treatment with doenjang. Although treatment with doenjang seemed to suppress NF-κB activation, it was not significant. Doenjang significantly suppressed tumor necrosis factor-α expression, whereas it did not influence interleukin (IL)-1β and IL-6 expression. However, doenjang increased IL-10 expression. Based on these findings, doenjang may promote gut health by regulating gut microbiota and its LPS concentrations and suppressing harmful enzyme production.

Abstract
OBJECTIVE Cardiovascular disease (CVD) is a leading cause of morbidity and mortality in postmenopausal women. Danshen, the dried root of Salvia miltiorrhiza Bunge, has been used clinically in China to treat CVD and dyslipidemia in postmenopausal women, and its major active ingredients have been found to have an estrogenic effect. The aim of this study was to elucidate the underlying mechanism of danshen's protective effects on vascular function in an ovariectomized (OVX) hyperlipidemic rat model. METHODS Thirty-five 6-month-old female Sprague-Dawley rats were randomly divided into five groups: sham-operated rats with low-fat control diet + vehicle, sham-operated rats with high-fat diet (HFD) + vehicle, OVX rats with HFD + vehicle, OVX rats with HFD + 17β-estradiol (1 mg kg d, PO), and OVX rats with HFD + danshen aqueous extract (600 mg kg d, PO). After 12 weeks of treatment, gains in body weight and serum lipid profile levels in rats were measured and histological examination of livers was carried out. Vascular function was evaluated by measuring relaxation responses. Molecular mechanisms were also analyzed in isolated aorta. RESULTS Treatment with danshen aqueous extract reduced body weight gain, improved serum lipid profiles, and prevented formation of fatty liver induced by HFD and OVX. In addition, danshen could increase endothelial-dependent vasorelaxation and displayed vasoprotection in OVX rats fed with HFD, primarily by stimulating nitric oxide (NO) production, up-regulating the mRNA expression of endothelial NO synthase, and down-regulating the mRNA expression of tumor necrosis factor α, intercellular cell adhesion molecule-1, and vascular cell adhesion molecule-1 in the isolated aortas. CONCLUSIONS We conclude for the first time that danshen aqueous extract could protect OVX rats fed with HFD from endothelial dysfunction. Its effect may be related to its abilities to normalize serum lipid profiles and enhance NO availability in the vascular system. Our findings indicate that danshen aqueous extract could be a promising natural supplement for postmenopausal women for preventing CVD.

Abstract
Various forms of fermented soybean products are well documented for their health benefits. The efficacy of anti-obesogenic effect of Doenjang, one of the most commonly used seasonings in Korean cuisine, has been reported only in animal models; thus, an evaluation of Doenjang needs to be conducted in human studies. We aimed to test the hypothesis that Doenjang supplementation reduces body weight and changes body composition in overweight adults. A total of 51 overweight adults participated in this study. A group of males with BMI ≥ 23 kg/m2 and waist to hip ratio (WHR) ≥ 0.90, and a group of females with BMI ≥ 23 kg/m2 and WHR ≥ 0.85 were randomly assigned to either a Doenjang supplement (9.9 g dry/day) group or a placebo group for a 12-week randomized, double-blind and placebo-controlled study. Anthropometric parameters, abdominal fat distribution by computerized tomography (CT) and blood components were measured before and after the intervention period. After the 12-week study, the Doenjang supplementation group had significant reductions in body weight (kg), body fat mass (kg) and body fat (%) compared to the placebo group, the supplementation of Doenjang resulted in a significant reduction in visceral fat (cm2), although no changes were observed in total and subcutaneous fat are as (cm2), serum lipid profiles and dietary intakes. The present study demonstrated that daily supplementation of 9.9 g dry/day of Doenjang for 12 weeks reduces body weight and visceral fat in overweight adults.
