I am amazed that I had to read more than 20 articles, including university studies, to get concrete information. The high majority of articles talk in terms of %. Percent has no meaning unless there is a hard figure to know what the % is of. I still haven’t found enough info, but I have found some.
It seems that the FDA has a recommended arsenic limit for children of 100 parts per billion. Even if we believe this, we still have to consider other sources of arsenic in our diet…such as the radish we pulled out of the ground, brushed off, and ate. Arsenic is a naturally occurring trace element.
Brown rice appears to have 154 parts per million. So there is substantially more arsenic than the FDA would like.
If washing can reduce arsenic 60%, then that takes the levels down to under the FDA threshold….in terms of parts per billion.
What I don’t know are the limits for an adult. And, I don’t know how much rice I would have to eat for that 154 parts per billion to amount to a problem. Do I need to eat a cup of rice for there to be a problem … or do I need to eat a 55 gallon barrel of rice?
Right now, to me, this is looking like the Cranberry findings of the late 1950s. I am sure I would rather than less arsenic than more. Other than that I can find very little out there.
