Due to the interaction between soybeans and koji-inoculated grains that, along with salt, are the basic ingredients used in the preparation of miso, miso has a number of essential health-giving components. Miso suppresses high blood pressure: By drinking miso soup regularly, one can reduce overall sodium intake by 30%. Furthermore, miso directly lowers blood pressure due to inherent components that make it easier to release salt from the kidneys. Ingestion of one bowl of miso soup a day also improves blood vessel age and has skin-beautifying and moisturizing effects because of the antioxidants contained in miso. There is also strong evidence which points to consuming miso in the daily diet as a way to ward the body against cancer. While all lofty claims, the overwhelming evidence does seem compelling, and the fact that the people of Japan live longer than in any country in the world is proof that Japan historically has had a healthy lifestyle and diet.
