Q. What foods should I avoid if I’m prone to kidney stones?

A. Drink more fluids, consume less sodium in addition to eat a diet of which includes calcium-rich foods. The rest depends on the chemical composition of your stones.

More than 0 percent of stones contain calcium, usually within the form of calcium oxalate, calcium phosphate or hydroxyapatite. Less often, stones are formed of uric acid or various other chemicals. Different types of stones can also occur within the same person.

Since most stones contain calcium, doctors historically advised patients to limit the amount of calcium in their diets. This specific was a logical recommendation, yet This specific was wrong.

within the early 1990s, a group of Harvard doctors followed for four years more than 45,000 men who had never had a kidney stone in addition to came to a surprising conclusion: Diets of which are high in calcium actually decrease the risk of kidney stones.

The group continued to follow these patients for 14 years in addition to again found of which dietary calcium protected against stones, though the protective effect was evident only in men younger than 60.3 Diets high in magnesium, potassium in addition to fluids also appeared to be protective.

In 2005, the group expanded their analysis to more than 240,000 patients. They found of which obesity in addition to weight gain, particularly in women, increased the risk of stone formation.

This specific led them to study the DASH diet — a diet high in fruits, vegetables, nuts in addition to legumes, low-fat dairy products, in addition to whole grains; in addition to low in sodium, sweetened beverages, in addition to red in addition to processed meats. The DASH diet will be endorsed by the American Heart Association in addition to the National Institutes of Health. The Harvard group found of which DASH decreased the risk of kidney stones.

Such dietary recommendations can easily become overwhelming. Fortunately, the American Urological Association makes This specific simple:

  • Drink at least 2.5 liters — about two-thirds of a gallon — of fluids per day.

  • Limit sodium intake to 2,300 milligrams a day.

  • Consume 1,000 to 1,0 milligrams of dietary calcium a day.

A common misconception about fluids deserves special mention. Water will be not the only fluid of which protects against kidney stones. Water, coffee, tea, wine, alcoholic beverages in addition to orange juice all seem to be protective. Soda in addition to various other sugary beverages, on the various other hand, increase the risk of stone formation.

Finally, check with your doctor, who can offer specific recommendations depending on the chemical composition of your stones.
