I haven't heard of an epidemic among Paleo eaters.
I was wondering if anyone has any thoughts on the relationship between eating Primal foods and the potential risk of developing kidney stones? I know calcium oxalate stones are the most common but that stones can develop in people in different ways. However, I have found a common reason for someone developing them can be by consuming foods high in oxalates (ie. meat, green leafy veggies, nuts, beets, tea etc.) that are basically staples in a Primal person's diet. I know a lot of these foods are in mine.
I don't have a history of stones (or anyone else in my family) and it has only been brought to my attention over the last couple months that I have some. Thankfully, no painfull stone-passing to date. I have been Primal for over a year now and it has changed my life.
Wondering if this is in fact potentially diet-based (consuming too much high-oxalate foods in the form of meat, veggies and nuts primarily) if so, I can't be the only Primal person developing stones, as I'm not sure what else could be causing them? I have already had urine and blood work done and everything is normal. I know staying hydrated is key. As Mark suggests, I drink water throughout the day as required and as I get thirsty.
This is a puzzling one for me...
Even experts can't agree on this one. I'd definitely steer clear of the tea and greens in excess if they are oxalate stones. Some say eating more acid things can help, others say alkaline. I've even seen ACV recommended.

Wrong. Meats are low-oxalate food. However, there might be another problem - uric acid, but I admit I know very little.
Anna's right about animal products. Plants are the only thing that have oxalates.

Also, there is some evidence that taking excessive supplements can lead to kidney stones.
Can calcium supplements cause kidney stones? - Washington Post
Washington Post and Livestrong? For fuck sake, I thought people on this forum would be beyond that.
"It is extremely important to realize that calcium deposits in soft tissues become worse when the diet is low in calcium. Persons suffering from arthritis, bursitis, scleroderma, hardening of the arteries and any abnormality where calcium deposits or spurs may cause pain are often afraid to eat foods rich in calcium. Actually they can never improve until their calcium and magnesium intakes are adequate. Not infrequently physicians tell individuals with kidney stones to avoid all milk, thereby causing stones to form even more rapidly. Such calcium deposits can also occur when vitamin E is undersupplied. After open-heart surgery, when both magnesium and vitamin E are drastically needed and could easily be given, the calcification of heart muscles often becomes so severe that it can cause death within a few days. Pages 171-172, Lets Eat Right to Keep Fit, Adelle Davis, Signet, 1970."

I thought there was a proposed mechanism whereby kidney stones occur as a result of fructose consumption, but I don't have a cite handy.
And WTF is wrong with Livestrong and the Washington post as sources? I just picked those two from the long google fu list that said the same things.
Have you not had enough coffee yet today Derp? You seem a little pissy.
Personally, I did have kidney stones after starting a primal diet. I suspect that it is either from taking a lot of Vitamin D3 without any K2 or from being in Ketosis too frequently/long. My understanding is that children on a ketogenic diet long term have a pretty high rate of developing kidney stones.
It is also possible that they formed before I was primal and passed then, but I have no way of knowing for sure.
