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.

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.
