Inspired by Tatuichiro Akizuki's experiences post atomic bomb Nagasaki and European historical accounts from Ukraine nuclear power accident. Hiromitsu Watanab's study* in Journal of Toxicologic Pathology points to solid findings not only for radiation exposure victims but also for sufferers with colon cancers, gastric and lung tumours.
Hiromitsu has published a number of studies on the therapeutic efficacy of Miso* ** ***. Via the monitoring of the number of surviving intestinal crypts (glands) post irradiation, Mr Hiromitsu was able to establish that Miso has a significant beneficial effect.
It further point out that the longer fermentation for Miso being an important factor (Miso is a paste traditionally to Japan and parts of Asia. It is a fermented paste made from soy beans and is often combined with other ingredients such as barley, rice, oats, wheat each making a specific variety) with 180 day ferment being seen as ideal.
The study also points out that consumption of miro needs to take place very close to the exposure event with the protective element declining to 0 after 2 days.
Miso paste is a main ingredient in Miso soup, a staple food in Japan which is made in combination with wakame and other seaweeds such as commonly available nori. The recipe can be as simple as a little spring onion, tofu, miso paste, seaweed and some hot water. I will however add at this point that in Australia many miso pastes are actually subjected to pasteurization, a process that would kill the active ferment agents. I would say that it is important the a miso that is active would be necessary. One product that I am aware of is Muso brand of Barley Miso. It comes in a little tub labeled as unpasteurized and certified organic. It is available from many health food retailers such as these Link.
Given that the Fukushima disaster continues to dump huge volumes of radiation into the ocean it would be prudent to review the studies below with a view to preventative diets.
Should you have concerns about your digestion, liver or other ailments please raise it at your next shiatsu consultation where I am happy to answer any questions.
