Dietary Modifications

Reduction of salt consumption is important, as excess salt intake is coupled with increased excretion of urinary calcium.[2,10,12]

Decreased intake of dietary calcium implies increased intestinal absorption of oxalate, limiting its urinary excretion, and is detrimental for bone health and growth, as well as vitamin D deficiency;[2,29] therefore, no reduction of calcium intake should be planned.

Both excessive protein intake and protein restriction should be avoided. Vegetables and fruit should be well represented within the diet, being excellent sources of citrate and potassium, acting as kidney stone inhibitors.

Reducing food with high oxalate bioavailability (like chocolate and cola) and purines may be useful in case of secondary hyperoxaluria and hyperuricuria, respectively.[1,34]
