Oddbean new post about login | logout I'll be eating kimchi and miso soup, because I don't think it is healthy to go without some plants and bacteria. Once I'm done with my keto period I will reintroduce things like cabbage and swedes.
i don't think there is any reason to leave them out entirely, though cabbage can be a problem with oxalates (and the whole brassica family) again, probably a kidney thing, since oxalic acid forms a highly insoluble solid with calcium
Spinach and rhubarb are oxalate heavy. So is tea. Anything that makes your teeth feel dry is probably oxalate heavy. But cabbage and brassicas aren't.
