DASH Diet for Oxalate Kidney Stones

I believe excessive protein intake can increase urinary calcium excretion,
thus theoretically increasing the risk of calcium stone formation. Some
interventions I like to use for reducing the risk of stone formation are
lots of fluids, increase fruit, vegetables, moderately low oxalate legumes,
low-fat dairy (there was one trial showing DASH style diet reduced calcium
oxalate supersaturation better than a low oxalate diet), reduce sodium
intake if excessive, reduce protein intake if excessive, take calcium
citrate with meals (especially meals high in oxalate), incorporate
probiotic foods, swap high oxalate foods with similarly healthy lower
oxalate foods. Make sure total calcium intake at least meets current ASMBS
guidelines, but is not above the UL.
