In reply to Justin. Thanks for letting me know. I updated the links that are still available and removed some that aren't.

The file, “Oxalate Content of Foods.xls” is given as a dead link. There are a few dead links on this page. Using IPFS, these resources can be saved in a more robust way.

Just wanted to thank you for this excellent article. I stopped my very enjoyable vegan diet due to a number of non-stone health problems that I discovered (proved) were due to oxalates. It was awful to give up spinach, quinoa, brown rice, soy, beans and nuts, etc and to incorporate dairy into my diet but I literally felt like I was dying from oxalate overload.
Doctors have been useless since I don’t have stones.
My main oxalate issues were severe muscle and joint pain (fibromyalgi and arthritis), profusely and spontaneously bleeding gums and inability to empty my bladder/ having to pee every 15 minutes. There were others. The symptoms return when I eat any moderate to high oxalate foods; like eating more than 2 dates on my oatmeal or more than 1 serving of beans causes symptoms. Eating lots causes disability.
Anyhow, I will experiment with adding potassium citrate, grapefruit juice and/or lemonade. I tried calcium citrate and dont think it helped but may have been taking it wrong, or with wrong expectations.
Your post is helping me to sort it out and I’m encouraged to learn that animal products don’t help in any way because I thought veganism was the issue.

In reply to Kj. Hi KJ I wondered if you were still online and if you had been stone free since taking the two supplements you mentioned?

Thank you so much for this valuable information on Oxalates in foods. There is a well-know Doctor who has
written a book and capitalized on the fear and potential health problems in foods high in “anti-nutrients”. He has exposed that
yes, many plant foods have lectins, goitrogens, phytates, and oxalates in them. But also scared so many humans
away from consuming plant foods as they are “dangerous”, in the process of making millions $$$ and selling supplements
to cure related problems, and, promoting that “healthy” pastured animal products are okay to consume. On the flip side,
however, are multiple studies that show that vegans (and vegetarians) have lower rates of kidney stones, obesity,
diabetes, and many types of cancers, etcetera. Plants are good for us but some have sensitivities/allergies, and, some of us
also need to choose carefully. I consume green smoothies every day, but do not add swiss chard or handfulls of spinach.

In reply to Georgina Cook. While it is best not to take a calcium supplement at the same time as eating iron-rich foods or taking an iron supplement (because there is evidence that calcium supplements can inhibit absorption of iron), the same may not be true for calcium-rich and calcium-fortified foods. This small study found that calcium-fortified foods did not inhibit iron absorption. It's best to eat a variety of sources of iron and calcium throughout the day.

I found this article as I am trying to do the best with respect to maximising absorption of iron and calcium from my daily green smoothie. I typically would have 3oz spinach and 3 oz kale, 100ml calcium fortified soy milk (calcium carbonate providing 120g calcium per 100ml). Is some of the iron bound up with oxalate, so would the calcium bind with oxalate and so help with iron absorption? Would the calcium inhibit absorption of iron? THere are some research papers suggesting calcium supplements can inhibit iron absorption. What is best to do when both calcium and iron are priorities?

In reply to Hazel. I, too, am a vegan with kidney stones and all my favorite foods are high in oxalate! I suggest you look at the work of Dr. Fredric Coe, U of Chicago, who has found that consuming citrate prevents the binding of CA with oxalate. I get my citrate through magnesium citrate and zinc citrate supplements, since I need those elements, anyway, and some through lemon water.

In reply to Hazel. Hazel, Yes, under certain conditions for some people explained in the section Hyperoxaluria. But there are no known exact amounts that we can say are going to do this for every person. The point to understand is that with every very high-oxalate food you eat, you're slightly raising your risk.

I cant remember whether I posted this link here, but anyway http://oxalate.org/ — good database online with sources for each data item
