Re: Nitrates in Greens




Michelle / Suzy -

This is something I've been concerned with for some time after running
across the old New Alechemy information regarding dangerous levels of
nitrates in winter greens. My own subsequent research  revealed that
actually a fair amount of literature has been written on this topic. I have
a rather large stack of information here from Woods End (the lab which did
the analysis for New Alchemy) which I have not had a chance to fully
analyze. After  I do, I'll put up a page on my findings, but I can pass on
the paraphrase of the study:

In the summer, eat salad, in the winter, drink soup

or

even natural people can't get away with fooling Mother Nature.


It's these little quirks where logic fails and common sense is not
realiable enough for us to be certain that our product is not detrimental
to the people who eat it that draws to my attention how necessary it is for
all of us who are working to produce healthy food for healthy families to
find associations such as this one where we can share and discuss   both
the front and the backsides of novel, and seemingly harmless,  methods of
increasing our productivity and yields.
