It is now widely known that anti-cancer effects are expected from intake of miso on a regular basis. According to a decade-long survey from 1981 conducted by Dr. Takeshi Hirayama of the National Cancer Center, people who do not eat miso soup at all are at 50% higher risk of dying of stomach cancer than those who eat it every day. Scientists believe that ingredients contained in miso such as unsaturated fatty acid, isoflavon, yeast and lactic acid have a function to control variant substances that are closely related to generation of cancer. Also, miso has been proven to have effects of scavenging cancer-inducing radioactive substances. Another characteristic of miso is its anti-tumor effect. That is because soybeans , of which miso is made, contain trypsin inhibitor that has anti-tumor effects . Furthermore, vitamins and dietary fiber in vegetables used in miso soup are known to have anti-cancer effects as well. As mentioned above, you can prevent cancer before you know it by taking miso soup every day. These immeasurable effects of miso have attracted a worldwide attention, and studies are conducted in various industries.
