Fern Bracken (Go Sa Ri) and Cancer?

  • 3
  • Share

I've never eaten too much fern bracken because I've read about its possible carcinogenic properties. I've read several reports about fern bracken being carcinogenic and toxic to some animals. I've also read some stuff about it being implicated with some cancers in human beings. Fern Bracken is eaten in Korean and Japanese cultures (and perhaps some others as well), and they've got one of the highest rates of stomach cancer in the world. Of course, there could be other explanations -- genes, high sodium, etc. And it is very difficult to prove causation in these cases. Does anybody have more information about fern bracken? Any botanists out there?

    1. re: mlgb

      Thanks for the review. That was helpful. I guess it's still not widely understood. With my huge family background of cancer, I think I will pass on this item. Too bad -- I was thinking of attempting to make "ropa vieja" with fern bracken.

    2. Oh dear. This is terrible news for me. I love kosari, and was planning to make a huge batch soon. I looked at the study, and certainly the evidence is not conclusive. But the animal studies are concerning.

      What to do, what to do. I am having a tizzy of a time, what with Listeria and deli meats, and cheese and Salmonella. Seems like there is a new thing not to eat every week... :(
