Miso soup is a staple of the traditional Japanese diet and has long been anecdotally connected with Japanese people’s famously long life expectancy. Now, research has linked consumption of miso soup with a reduced risk of stomach and breast cancer.
Japan’s cancer rates are low compared to western countries, but the country’s relatively high rates of stomach cancer have often been blamed on the high sodium content of the traditional Japanese diet. However, research suggests that miso, the fermented soybean paste which makes the base of miso soup and many other Japanese dishes, could actually counter-act the harmful effects of sodium consumption and even smoking.
