Have been researching dairy substitutes and so far I have found that rice milk is lower in oxalates than my usual almond milk but higher in potassium and phosphorus. 1 C almond milk has 35 mg K or just under 2 % recommended intake for CKD patients and 20 mg P or 2 % of the recommended amount. On the other hand, 1 C rice milk has 64.8 mg K or about 3 % of the recommended intake and 144.4 mg P or 14 %. I'm thinking the lower-oxalate rice milk might be a better choice for someone with a history of kidney stones as long as the potassium and phosphorus intake from other food sources is reduced so the total daily limits aren't exceeded. I haven't counted calories or carbs here. I would appreciate others' opinions and feedback.
