Re: the oxalate and calcium content of vegetables. The first column of
the table below is from
         http://magpage.com/~laurat/petbunny/oxveggie.html

The second and fourth column are from
         http://www.nal.usda.gov/fnic/cgi-bin/nut_search.pl

The third column is the ratio calcium/oxalate. High numbers correspond
to high calcium availability. For instance, the ratio is 0.10 for
spinach and 6.75 for kale. The fifth column is the ratio calcium/phosphorus.

We see that coriander, kale and turnip greens are excellent sources of
calcium (high in Ca, low in oxalate).

Of course, the information below is of limited value because the
oxalate and calcium content of vegetables may vary according to
variety, origin, soil fertilization, etc. but they nevertheless give
an idea about which vegetables are good sources of calcium.

P.S. Does anyone know the French word for "collards"? I can't find it
in my dictionary ("Robert and Collins" has 220,000 words and
locutions), and that vegetable is not sold in groceries here!
