Tom: I mention calcium/oxalic acid as an aside, make it very clear that I really don't have the time to cite refs (as I am super busy with other efforts), yet the questions on this topic simply won't stop. Folks, you can access Medline as easily as I can. Instead of asking me, please check Medline (available for free on the web, use search engine to find URL) or the Biosis database (not on the web; some University libraries have access). Thanks. PS this is an example of how threads tend to take on a life of their own. I never intended to start a discussion on exactly which veggies contain exactly how much oxalic acid, or how nuch it is decreased by cooking. It was and is my intent that folks seeking such details need to look up the information in the scientific literature. Signing off this thread... Tom Billings
