Effects of Immature Soybeans on Lipid Metabolism in Rats Fed Normal and High-Fat High-Fructose NAFLD Diets.

Edamame and chamame (brown edamame) are immature soybeans that contain abundant protein, vitamins, and dietary fiber. Edamame has a different nutrient composition compared with mature soybeans, as evidenced by its higher content of vitamins and folic acid. Recent studies have shown that proteins in mature soybeans, such as β-conglycinin, and dietary fiber influence the metabolism of lipids such as triglyceride and cholesterol.

Combined Citrulline and Glutathione Supplementation Improves Endothelial Function and Blood Pressure Reactivity in Postmenopausal Women.

Postmenopausal women (PMW) may experience endothelial dysfunction associated with arginine (ARG) deficiency relative to asymmetric dimethylarginine (ADMA) caused by oxidative stress. Endothelial dysfunction contributes to increased blood pressure (BP) responsiveness to sympathoexcitation induced by the cold pressor test (CPT). We investigated the effects of citrulline alone (CIT) and combined with the antioxidant glutathione (CIT+GSH) on vascular function.

Prolyl-hydroxyproline, a collagen-derived dipeptide, enhances hippocampal cell proliferation, which leads to antidepressant-like effects in mice.

Depression has been a mental health issue worldwide. We previously reported that ginger-degraded collagen hydrolysate (GDCH) suppressed depression-like behavior in mice. Furthermore, prolyl-hydroxyproline (PO) and hydroxyprolyl-glycine (OG) were detected in the circulating blood after the oral administration of GDCH.

Ginger-Degraded Collagen Hydrolysate Exhibits Antidepressant Activity in Mice.

Collagen is the most abundant protein in animals. Collagen hydrolysate has been found to have multiple functions in the skin, bones, joints, muscles, and blood vessels. Recently, it has been reported that the low molecular weight fraction of collagen hydrolysate exhibited anxiolytic activity, suggesting that collagen peptides affect brain functions.
