Re:muchos gracias, compadre

Hi Trapper, you mean the leaves, not the cow, right? :). I do eat a fair amount of greens, but possibly need more. My naturopath often finds me calcium deficient, though she's using kinesiology to test me, and I'm always unsure about whether there's room for a certain amount of practioner error/influence with that testing.

I just googled sources of calcium, and seaweeds came up right at the top (on this list, anyway) - hijiki, wakame, kelp and kombu were #'s 1-4. at 1,400-800mg of calcium per 100g portion. Oddly, spinach isn't on this list, but turnip greens are 191 , watercress 151, spirulina 131. Sardines are 443. Hmm....

Good think I like sea vegetables, anyway. I wonder if the dried norwegian kelp powder is a good source? I guess that's the least likely to be contaminated.
