This probiotic-rich food contains exceptionally high levels of vitamin K2 for bone health and nattokinase, an enzyme studied for cardiovascular benefits. Typically served over rice with condiments like mustard or soy sauce, it provides complete plant-based protein while offering a unique umami flavor profile central to Japanese breakfast cuisine.
