Thank you
@Asklipia for starting this thread. My duties are finally over and I can get back to thinking about interesting things. I am pleased to note that the gain of PEM reduction which I have made over the past 6 months or so seems to be holding. Despite really pushing myself at times I have just been a bit tired today - no crash. And even better, my improved alcohol tolerance is continuing. Wine is one of life's great pleasures but I was worried I had really gone too far last night. Today though just a little tiredness.
Anyhow I have attached a list I made for myself of the oxalate content of various foods. It is not meant to be exhaustive - just foods I might want to eat. I didn't list actual content for all foods, but tried to illustrate things like how cooking method can make a difference. I simplified the categories also, aiming for a quick guide that would result in a medium oxalate diet without fussing too much.
As noted above, cooking method can affect soluble oxalate content. Boiling is not a method I prefer but it can make a big difference so now I use it sometimes. Fermentation doesn't seem to make much difference.
Variety can make a big difference and I have listed several examples of this - see particularly legumes.
Finally since greens seem to be a big problem area I will just list again some good choices - all types lettuce, rocket (arugula), basil, coriander (cilantro), watercress, all kinds of cabbage, bok choy, turnip and mustard greens, cavallo nero and purple kale.
While bok choy is the only chinese green tested, I think any of them are likely to be safe since they are of the cabbage family which seems to be universally low. I regularly eat choi sum, gao choi and chinese broccoli and have never had any problems with them.
