[Prior Art] At present, various diseases in developed countries around the world have been considered to be mainly caused by an excessive increase in in vivo metabolism due to satiation. In other words, the increase in metabolic activity in vivo increases oxygen consumption, and as a result, the amount of active oxygen generated in the process of water being produced by four-electron reduction of oxygen in mitochondria is increased by the endogenous antioxidant enzymes. It has become clear that a variety of diseases can be caused by such cases, and it is now an important issue (renal and dialysis 24
