Dietary guidelines for sodium
Avoid excess sodium
Excess dietary sodium may increase the risk of stone formation because high levels of sodium (“salt”) increase the amount of calcium excreted into the urine. But how much sodium is too much? The Dietary Reference Intakes (DRIs) recommend no more than 1500 mg daily for most adults.
Keep in mind that salt from the salt shaker typically accounts for only 10% to 15% of daily sodium intake. The rest comes from the foods we eat—so monitoring nutrient labels, and limiting processed, convenience, and restaurant/takeout foods, as well as other high-sodium food choices (see table below), is key to successfully managing your daily sodium consumption.
