well, brassicas are a bit of a minefield too, in general, because of oxalic acid... cabbage, spinach, kale, etc, in the circumstances of me having what are clearly minor kidney stones (and yes i am guzzling water like a dog on a hot day)

lettuce is ok but it doesn't seem to work so well in helping the fat absorption - spinach is one of best, the baby leaves, because they are very low in oxalates and have good quality fibre, but here on madeira quite hard to find, and plenty of lettuce and brassicas tho, which is useless to me

gonna be checking the vegetables sections on my trip to the shops later today, try and find a good, low irritant, low carb fibre source
