Traditional fermented soybean foods, acting as potential synbiotics, may help mitigate cognitive impairment associated with amnesia. This study investigated the neuroprotective effects of four kanjang (Korean fermented soy sauce) varieties and their underlying mechanisms. Male Sprague Dawley rats (n = 70) were divided into seven groups: normal control, scopolamine control, positive control (1 mg/kg bw/day of donepezil), and four scopolamine-treated groups receiving different kanjang varieties (0.

This study investigated associations among gut microbiota profiles, diet, lifestyles, and CTT in individuals with subjective constipation.
Methods: We conducted a secondary analysis of data from our randomized clinical trial, examining gut microbiota composition, CTT, and dietary intake in baseline and final assessments of 94 participants with subjective constipation.
Cheonggukjang () is a traditional food, made by the fermentation of beans, and it has different recipes for different regions in Korea. However, it has anti-inflammatory, anti-cancer, and anti-obesity effects, and is known to affect changes in the intestinal microbiota. In this study, we investigated the immune-enhancing effects of four type s (one commercial and three transitional s).

This study investigated the efficacy and mechanism of traditionally made kochujang(TMK) with different capsaicin levels to alleviate memory impairment in rats with scopolamine-induced amnesia. Sprague-Dawley male rats were administered scopolamine (2 mg/kg bw/day) intraperitoneally to suppress the parasympathetic nervous system(PNS) and induce memory impairment. The rats were divided into four experimental groups, each consuming a diet containing 1 % kochujang in a 43-energy% high-fat diet(HFD) for 8 weeks.

The rats were categorized into six groups: Control, cooked unfermented soybeans (CSB), and four TMDs based on () and biogenic amine contents analyzed previously: high (HS) and high biogenic amines (HA; HSHA), low (LS) and HA (LSHA), HS and low biogenic amines (LA; HSLA), and LS and LA (LSLA). The rats in the CSB and TMD groups fed orally had a 4% high-fat diet for 12 weeks.

It has been speculated that regular consumption of Jang may lower the risk of metabolic syndrome (MetS). We hypothesized that Jang intake was associated with the risk of MetS and its components after adjusting for potential confounders, including sodium intake.

We aimed to evaluate the effects of four TMD types, containing low and high amounts of species and biogenic amines (HBHA, HBLA, LBHA, and LBLA), on energy, glucose, and lipid metabolism, by altering the gut microbiota in estrogen-deficient ovariectomized (OVX) rats. Their mechanisms were also examined.
