Diet Plan For Kidney Stones

A kidney stone is a hard and a solid lump that forms in your kidney. It is a painful condition if unchecked may become serious. The lump can be as small as a tiny pebble or it can be much bigger. It is made out of the waste products in your urine. People who are affected by kidney stones generally tend to have stones with the same composition each time. Since some dietary components contribute to stone formation, limiting intake of foods that contain these components is advised.

Root Causes of Kidney Stone

  1. Not drinking enough fluids, especially drinking water
  2. Hereditary/ Family history of kidney stones
  3. Eating a diet high in protein and sodium but low fiber
  4. Being a man between 20 to 70 years of age

The Foods to be Avoided In Kidney stones

A healthy kidney stone diet plan starts with simply drinking more water. One will need to reduce the amount of salt that you consume. This can be also because of purchasing fresh veggies instead of canned vegetables. Buying only reduced salt/sodium condiments and preparing meals instead of buying prepared meals will also help in the kidney stone diet plan. Most importantly avoiding salt and the usage of substitutes will add great value. Avoid consumption of beer, sweet potatoes, oranges, berries, cranberries, tofu, beets, beans and rhubarb items. Foods you should avoid at bare minimal limit are eggs, pork, red meats, fish and poultry.

Solid Diet Plan for Kidney Stones

I. Sodium, Calcium & Protein

Kidney stone patients should also be careful on their sodium intake as calcium can crystallize in the urine.  Not adding salt is a good way to decrease the daily sodium intake. Exercise caution when consuming foods like hot dogs, deli meats, sausage, canned food, dry soup mixes, sauerkraut and pickles as their ingredients are potential threats.


Too much protein in the diet can also cause kidney stones. Two to three servings of protein a day is sufficient. The National Kidney Foundation advises patients to see if they are eating the proper amount of protein when devising a diet as protein foods include meats, nuts, eggs soybeans and dairy products.


Doctors normally advise their patients to avoid calcium as many kidney stones are calcium-based. However, experts are now saying that not having enough calcium in the diet can actually form stones.

II. Water Consumption/Hydration

Kidney stone patients are advised to drink 6 glasses of water/fluids each day.  The reason is that to produce two quarts of urine to minimize the formation of calcium and other deposits in the kidneys. Sufficient water intake is necessary to flush out waste through urine. The more diluted the urine is, the less likely a stone will form. It is important to drink lots of fluids even after a stone has formed.
