I didn't include most grains or starches in my original post about oxalate levels of foods, as I don't tend to eat them (I follow essentially a low oxalate paleo type diet). However, a number of other people have asked about this so I thought I'd pass along the numbers. This information is taken from the main spreadsheet in the files section of the Trying_Low_Oxalates yahoo group. I highly recommend that anyone who really wants to know about oxalates and to reduce their load in the diet should join the group and get access to this document. It is based on the most up-to-date information available. Be aware that almost all the information that you find online is outdated and often very, very wrong. This list only includes GF grains and no soy products.
This is the total oxalate per serving info in mg per 1/2 cup unless otherwise noted. Some of the info may seem confusing (such as the two entries for cooked quinoa) but that is how it was in the original document, so I included it. Oxalate content will vary sometimes depending on where it was grown, and many other factors, so this is always a bit of an approximation anyway.
