A Kidney stone is a hard piece of material that forms in the kidneys when calcium, phosphorus or oxalate substances in the urine become concentrated. The Kidney stones are one of the most common urinary tract disorders and may be extremely painful to pass.
Identify the Kidney Stone
Diagnose the kidney stone first with the physician. Two types of kidney stones could be affected by the diet, such as the calcium stones, which include calcium oxalate and the calcium phosphate stones, and uric acid stones. The calcium oxalate stones are the most common and can be caused by the high calcium and oxalate excretion; whereas the calcium phosphate stones can be caused by both high calcium and high pH levels in urine. The uric acid kidney stones are formed, when the acidic urine that has a low pH becomes concentrated with the uric acid.
Researchs have found that certain minerals, foods and fluids may actually promote the kidney stone formation, especially in susceptible individuals. Learning what foods to avoid to helps to prevent the recurrence of these stones.
Limit Animal Protein
Animal protein may increase the risk for both calcium and uric acid stones. The Purine is a compound found in the animal protein that is broken down into uric acid in the urine and can lead to uric acid kidney stone formation. The foods highest in the purines include organ meats, such as the heart, liver and kidney; sardines; mackerel; anchovies; codfish; mussels; scallops; herring; shrimp; bacon; veal and gravy. Avoid these foods if one is at risk for the uric acid kidney stones. The acid in the animal protein can also increase the calcium and decrease the citrate excretion in urine, which may be associated with the increased risk for the calcium kidney stones. To prevent recurrence of the uric acid and the calcium stones, one should limit the animal protein to 6 ounces a day.
Avoid the Sodium
High salted foods like hot dogs should me avoided.
The sodium may increase the risk of the calcium oxalate and the phosphate kidney stones, causing the kidneys to excrete more calcium in urine. The calcium can combine with the oxalate and the phosphorus to create the stones. To limit sodium to 2,300 mgs a day, avoid the high-sodium foods, such as the fast foods, the canned soups and vegetables, the pickled foods, the processed frozen meals, the luncheon meats, the hot dogs and the snack foods. Look for hidden sources of sodium on the ingredients list, such as the monosodium glutamate, the sodium alginate, the sodium nitrate or nitrite, the baking powder, the baking soda and the disodium phosphate.
Avoid the Oxalate & Vitamin C
Limit the spinach intake.
Limit the quantity of the oxalate in the diet, if at risk for the calcium oxalate kidney stones. The foods that are high in oxalate can increase levels in urine. For e.g.; spinach, beets, nuts, chocolate, etc. When oxalate combines with calcium, the calcium oxalate kidney stones are formed. There is also some evidence that doses vitamin C or ascorbic acid supplements greater than two thousand mgs, may increase the kidney stone formation in those who are at risk.
The Stone-Promoting Fluids
The fluid intake is very important for those with the kidney stones. The fluids dilute the urine and reduce the concentration of minerals that form kidney stones. The choice of the right fluids is the key. Some research shows that certain fluids(e.g.; dark colas), contain the phosphoric acid and may increase your risk for the kidney stones. The Soda intake in general is associated with the weight increase, which is also increasing the risk for kidney stones. Avoid the soda altogether to help in reduce recurrence of the stones. Mostly drink water and aim to consume it between 8 – 12 cups a day, to help prevent all types of the kidney stones.
