Symptoms of kidney stones are pain in the back (slightly lower) or pelvic area and possibly blood in the urine. Often this condition is hereditary and can also be caused by infections or drugs.
By testing for kidney stones, it is possible to determine which foods should be limited in the diet.
Stones are usually calcium and oxalate. Excessive excretion of calcium may be related to parathyroid abnormalities, but may also occur due to excess protein in the diet.
Hence, it is recommended to limit daily protein intake to 8 or 7 ounces (198-226 grams) from meat, poultry, and fish.
Oxalates are found in a number of foods. But according to one study, only a few foods, other than protein, actually raise urinary oxalate levels, including spinach, rhubarb, beets, chocolate, tea, wheat bran, seed kernels, almonds, peanuts, and berries. are.
It is better not to limit calcium intake through diet, because less calcium intake increases the risk of stone formation.
Calcium binds with oxalate in the intestine and is excreted. Sodium stimulates the excretion of calcium and it is better to limit it to 2500 mg per day.
Caffeine increases the excretion of calcium. Very sweet drinks and citrus juice are known risk factors for the formation of stones.
Drinking water throughout the day is very important in diluting the minerals in the urine, drinking one to two glasses of water every 4 hours is recommended.
A high-fiber diet reduces urinary excretion of calcium.
However, some people do not absorb calcium well, so consuming too much fiber can lead to an overall calcium deficiency.
