Kidney stone patients should pay special attention to diet in daily life, some foods can aggravate the condition of kidney stones, the following is a list of foods that kidney stone patients should pay special attention to.
Control the intake of calcium
The majority of stones are formed by calcium or products containing calcium. If your last stone was mainly composed of calcium, you need to watch your calcium intake. If you are taking nutritional supplement crystals, the first thing you need to do is to consult your physician to see if it is necessary. The next step is to check your daily intake of foods high in calcium, including milk, cheese, cream and other dairy products. Milk and antacids may produce kidney stones.
Do not eat foods rich in oxalates
About 60% of stones are calcium oxalate stones. Therefore, limit your intake of oxalate-rich foods, including beans, beets, celery, chocolate, grapes, peppers, parsley, spinach, strawberries and vegetables from the kale family. Also avoid alcohol, caffeine, tea, chocolate, dried figs, lamb, drupes, green peppers, black tea, poppy seeds, etc.
Watch your protein intake
There is a direct correlation between kidney stones and the amount of protein intake. Protein tends to cause uric acid, calcium and phosphorus to appear in the urine, leading to the formation of stones. If you have had calcium stones, you should pay special attention to excessive protein intake, especially if you have a history of excessive uric acid or cysteine stones. Limit yourself to 180 grams of high-protein foods per day, which includes meat, cheese, chicken and fish.
Eat less salt
If you have calcium stones, you should reduce your salt intake. You should reduce your daily salt intake to 2-3 grams.
Avoid L-cystaminic acid
If you have a history of kidney stones or are currently suffering from kidney stones. Blood avoid L-cystaminic acid. The buildup of this amino acid can crystallize in the kidneys, creating large stones that clog the inside of the kidney.
Limit the amount of vitamin c
If you are prone to forming calcium oxalate stones, you should limit the amount of vitamin c you take. More than 3-4 grams a day may increase the production of oxalic acid, thus increasing the chance of stones. Do not consume high potency vitamin c supplements.
Do not take too much vitamin D
Excess vitamin D may lead to calcium buildup in various parts of the body. It is best to limit your daily intake of vitamin D to no more than the RDA limit of 400 IU.
Check your stomach medication
Some common acid preparations contain high levels of calcium. If you have calcium stones and you are also taking an acidulant, check the ingredients of the medication to see if it is high in calcium. If it contains high calcium, you should switch to another medicine.
Diet “Avoid” for kidney stones
There are several types of kidney stones. Once your doctor confirms the type of stone you have, changes in lifestyle can prevent and reduce the growth and development of stones. The following foods can help reduce the chance of recurrence
Drink more water
Regardless of the type of stone you have, the most important way to prevent them is to increase your intake of water. Water dilutes the urine and prevents high concentrations of salts and minerals from building up into stones. The proper amount of water to drink is 2 liters of urine a day, and that is enough. If you work in the hot sun all day, you need to drink 2 gallons of water.
Fiber supplementation
Adding rice bran will prevent stones from developing.
Eat foods rich in vitamin A
Vitamin A is necessary to maintain the health of the lining of the urinary tract, and it also helps to hinder the recurrence of stones. A cup of carrots provides 10,055 Iu of vitamin A. Other foods rich in vitamin A include green cauliflower, apricots, melon, pumpkin, and beef liver. (Vitamin A is toxic at high doses. Vitamin A supplementation should be approved by a physician before taking it.)
Supplementary nutrients
1, magnesium oxide or magnesium chloride
500 mg per day. Reduce the absorption of calcium. Research found that daily magnesium, can reduce the recurrence rate of 90%. Because magnesium and calcium – the same, both can be combined with oxalic acid. But with calcium oxalate is different, magnesium oxalate will not form painful stones.
2, vitamin B6
10 mg, 2 times a day. When used with magnesium, B6 can reduce the oxalate in the urine, which is a common mineral salt in kidney stones.
