I used to eat huge amounts of spinach..at least a couple cups a day and after a while I wasn't recovering from my workouts and my muscles were always sore. Google searches turned my attention to oxalates. I stopped eating spinach for a couple days and my symptoms improved drastically. Now I'm addicted to sweet potatoes and I'm getting the symptoms again...I would guesstimate I'm eating an average of 400 sweet potatoes calories per day. I just found out that sweet potatoes are high in oxalate as well?
I'm desperate.. I'm okay with eating less spinach but I'm in love with sweet potatoes and I really don't want to give them up.
I've heard calcium supplementation can help neutralize oxalates?
Anecdotal, but I believe I killed off my oxalobacter after some antibiotics and was seriously unable to eat beets without severe pain. I've been trying to eat a bunch of probiotic foods, and don't seem to have trouble with them now. Perhaps I re-introduced it the bacteria? I don't know if I specifically had trouble with sweet potatoes, but I think beets are typically higher in oxalates. Could be worth a shot...good luck!
Here is a good starting site about oxalates. They affect some people, others not so much. I have found my symptoms improve greatly when I avoid them. http://www.lowoxalate.info/ Calcium citrate (without magnesium) is supposed to bind to oxalates in food, but it is usually best to avoid high oxalate foods altogether and stick to low or medium oxalate.
