One of the most amazing chapters in the true history of healing foods comes from the final chapter of World War II, in the aftermath of the United States' dropping of two atomic bombs on civilian populations in Japan. Millions of innocent civilians were exposed to extreme levels of ionizing radiation, and rates of cancer immediately skyrocketed thereafter.


Yet some people seemed to be immune to the effects of harmful radiation... even people who were less than a mile from the epicenter of the atomic bombs. What was different about these people? As you'll learn here, they were all consuming a special kind of miso, a staple of the Japanese diet made from fermented soybeans, rice and salt.

Miso, as you'll see here, winds its way through the history of nuclear accidents and atomic bombs, always serving as a healing food with extraordinary properties that come from the fermentation process, not the soy itself. (Fermenting soy radically alters its chemical properties, changing it from an estrogen-mimicking food to an anti-estrogenic food.)



A study published in the journal Toxicologic Pathology entitled "Beneficial Biological Effects of Miso with Reference to Radiation Injury, Cancer and Hypertension   " details some of this enlightening history:


What Dr. Akizuki concluded is that drinking wakame miso soup before radiation exposure offered a significant radioprotective effect, effectively blocking the negative effects of radiation poisoning for those he studied.*

When the 2nd atomic bomb was dropped in Nagasaki on August 9th, 1945, physician Tatuichiro Akizuki, along with 20 employees, was taking care of 70 tuberculosis patients at "Uragami Daiichi Hospital" (St. Francis Hospital) about 1.4 km away from the hypocenter. However, these people including Dr. Akizuki did not have any acute radiation disease. Dr. Akizuki considered that this was the result of consuming cups of wakame miso soup (miso soup with garnish of wakame seaweed) every day. Later, this was translated into English and became known in the West. In the Chernobyl of nuclear power plant accident on April 26, 1986, in the Ukraine, many Europeans consumed miso soup as a preventive measure for radiation diseases. Therefore, Dr. Akizuki can be considered to be the first person in Japan to point out radioprotective effects of miso for maintaining health.


A simple, 10-minute miso soup recipe Ingredients:


  • 1/2 cup Health Ranger Select Organic Freeze-Dried Peas
  • 1/2 cup Health Ranger Select Organic Freeze-Dried Corn
  • 2 tbs Health Ranger Select Freeze-Dried Miso Powder (yellow or red)
  • 2 cups filtered water
  • Some chopped scallion.
  • 1 poached egg (optional)


    1. Add two cups of water into the pot. Bring it to a boil.
    2. Throw in corn and peas. Let it boil for another 3 minutes.
    3. Add Miso powder. Stir well.
    4. Sprinkle soup with scallion slices. Enjoy!


    The study mentioned here, published in 2013, was conducted by Japanese researcher Hiromitsu Watanabe. In it, he tested various types of miso on mice exposed to ionizing radiation. He was looking to answer the question of whether soybeans themselves have a radioprotective effect, or if the protection comes from something created by bacteria during the fermentation process (miso is made from fermented soy).

    The answer was clear: "The mechanism of the radioprotective effect of miso is considered to be closely related to substances produced during fermentation stage," Watanabe explains.

    Miso comes in different grades based on fermentation duration. The longer the fermentation time, the higher the grade and the more expensive the product. There's obviously a point of diminishing returns on this, too: beyond 180 days of fermentation, there's unlikely to be any additional measurable benefit to the miso. Even fermentation of just 3-4 days produces significant beneficial properties.


    If you eat miso, make sure it's made from organic, non-GMO soybeans. Soy is one of the most commonly genetically modified crops, so you have to choose organic to avoid the GMOs. You also have to be careful not to over-consume miso. The fermentation process can create glutamic acid as one of its products, and for those who are highly sensitive, even a little glutamic acid can cause a headache. Tomatoes and seaweed also contain glutamic acid, so if you're able to eat those without any problem, then you're probably not sensitive to it.

    Personally, I don't eat soy. No soy burgers, no soy protein, no soybean oil and not even steamed edemame. But I do eat small quantities of miso from time to time because fermented soy is unique. It's not the same food as unfermented soy.

    We cannot claim that this miso will have the same radioprotective effects of the miso products described in the studies listed above. They are not from the same manufacturers of miso, and they may differ somewhat in their molecular composition. So we are offering our miso purely as a health-promoting FOOD, and not as some sort of magic bullet defense against nuclear accidents or nuclear war.

    KOSHER icon

    Nevertheless, if you wish to enjoy a delicious source of organic miso, which is part of the health-promoting macrobiotic diet, we offer this honest, lab-verified miso in a convenient freeze-dried format. At the very least, you'll enjoy a nutritious source of health-supporting nutrients found in organic miso.
