Dietary bacterial cellulose modulates gut microbiota and increases bile acid excretion in high-fat diet-induced obese mice Open
Bacterial cellulose (BC), with its unique and highly viscous nanofiber structure, was the focus of this study. We investigated BC supplementation's potential for body weight management and its effects on gut microbiota and bile acid metabo…

Wet Grinder-Treated Okara Improved Both Mechanical Properties and Intermolecular Forces of Soybean Protein Isolate Gels Open
The application of okara treated by a wet-type grinder (WG) is discussed in this paper. We examined the effect of WG-treated okara on the mechanical properties and intermolecular forces in soybean protein isolate (SPI) gels. SPI gels were …

Applying a Wet-Type Grinder to Wheat Bran for Developing Breads Open
Despite being rich in dietary fibers, wheat bran is scarcely used as a food source because these dietary fibers have adverse effects on the texture. In this study, bran was atomized using a wet-type grinder (WG) to improve its physicochemi…

Effect of a diet containing a mixture of soybean isoflavones and soyasaponins on contact hypersensitivity and gut microbiota in mice Open
Dietary soybean isoflavones (SIs) and soyasaponins (SSs) individually exert inhibitory effects on contact hypersensitivity (CHS), which is an animal model of allergic contact dermatitis (ACD); however, the beneficial effects of diets conta…

Developing Soybean Protein Gel-Based Foods from Okara Using the Wet-Type Grinder Method Open
Okara, a by-product of tofu or soymilk, is rich in dietary fibers (DFs) that are mostly insoluble. A wet-type grinder (WG) system was used to produce nanocellulose (NC). We hypothesized that the WG system would increase the dispersion perf…

Applying Nanotechnology to Okara for Developing Soy Protein Gel-Based Foods Open
Okara, which is used in the production of tofu and soy milk, is rich in dietary fibers (DFs) and phytochemicals such as soy isoflavones and soyasaponins. Despite its nutritive value, okara is scarcely used as a food source, as the DFs in o…

Effects of voluntary exercise on plasma and urinary metabolites and gut microbiota in mice fed with high-fat-diet Open
The aim of this study was to examine the effects of voluntary exercise on plasma and urinary metabolites and the changes in gut microbiota in mice fed with a high-fat-diet. Healthy male C57BL/6J mice (four-week-old, n = 27) were fed a norm…

Improved effects of okara atomized by a water jet system on α-amylase inhibition and butyrate production by <i>Roseburia intestinalis</i> Open
Improving the physicochemical properties of okara for various applications in foods is of great importance. Here, okara and microcrystalline cellulose (MCC) were atomized using a water jet (WJ) system. The WJ-treated okara and MCC disperse…
View article: Effect of dietary cellulose nanofiber and exercise on obesity and gut microbiota in mice fed a high-fat-diet
Effect of dietary cellulose nanofiber and exercise on obesity and gut microbiota in mice fed a high-fat-diet Open
Cellulose nanofiber (CN) consumption with exercise could be a potential strategy to control obesity. Here, we studied the effects of CN supplementation and voluntary exercise on obesity and gut microbiota in high-fat diet (HFD)-fed mice. C…

Diets containing pomegranate polyphenol and soy isoflavone attenuate contact hypersensitivity in mice Open
Contact hypersensitivity (CHS) is frequently used as an animal model for human allergic contact dermatitis (ACD). Diets of pomegranate polyphenols (PPs) or soy isoflavones (SIs) each alleviated CHS symptoms; however, the effect of diets co…

Dietary soyasaponin attenuates 2,4-dinitrofluorobenzene-induced contact hypersensitivity via gut microbiota in mice Open
Summary Soyasaponins (SSs) are abundant in soybeans and display inhibitory activity against contact hypersensitivity (CHS), which is often used as a mouse model for allergic contact dermatitis (ACD); however, their therapeutic mechanisms r…

The Inhibitory Effect of a Polyphenol Concentrate from Pomegranate Juice on 2,4-dinitrofluorobenzene-induced Contact Hypersensitivity in Mice Open
Pomegranate juice (PJ) has higher polyphenol content and antioxidative activity than any other fruit juice. We used a pomegranate polyphenol concentrate (PPC) from pomegranate juice and investigated its inhibitory effects and mechanism of …

The inhibitory effect of soybean and soybean isoflavone diets on 2,4-dinitrofluorobenzene-induced contact hypersensitivity in mice Open
Murine contact hypersensitivity (CHS) is one of the most frequently used animal models of human allergic contact dermatitis. We investigated the inhibitory effects of soybean and soy isoflavone (SI) diets on 2,4-dinitrofluorobenzene- (DNFB…
