The process of kidney stone formation is a complex process, caused by many factors, not just excess calcium. Many people who eat a diet that is frugally low in calcium still get kidney stones, while many people who drink a lot of milk and eat a lot of shrimp and crab do not get kidney stones. So what is the diet for people who have had kidney stones to avoid recurrence? Below are 7 things to remember for people with kidney stones.

Drink plenty of water:This is the most important of the 7 things. Drink about 2.5 - 3 liters of filtered water every day (divided into several times a day) or eat and drink to have urine output of over 2.5 liters/day. Clear white urine shows that you drink enough water. Drinking plenty of water helps prevent kidney stones and helps expel small stones if any.

Eat less animal meat:Eat foods low in salt and low in meat. You can eat fish instead of meat. You can eat shrimp and crab in moderation.

People with kidney stones should avoid eating foods containing purines such as pork offal, sausages...

Eat foods containing calcium (milk, cheese) in moderation:You can drink about 3 glasses of fresh milk or an equivalent amount of dairy products such as butter and cheese (about 800-1,300mg of calcium) every day. You should not abstain from foods containing calcium too much because it will cause an imbalance in calcium absorption, causing the body to absorb more oxalate from the intestines and will create kidney stones. In addition, abstaining from foods containing calcium will cause osteoporosis.

In case of recurrent kidney stones, after testing there is evidence of polycalciuria due to increased calcium absorption from the intestine, it is necessary to abstain from calcium, but not completely abstain, but eat about 400mg/day, equivalent to 1.5 glasses of fresh milk.

Reduce foods high in oxalates:strong tea, coffee, chocolate, bran, cereals, spinach.

You should drink lots of fresh orange, lemon, and grapefruit juice:These drinks contain a lot of citrate which helps prevent stone formation.

Should eat lots of fresh vegetables:Helps digestion, reduces absorption of substances that cause kidney stones.

Avoid eating foods high in purinesCauses kidney stones such as: dried fish, dried meat, dried shrimp, sausage, fish sauce, pork intestines, beef intestines.

It should be noted that people with recurrent kidney stones should go for a check-up to find the cause of the recurrent stones in order to receive treatment and a specific diet appropriate for each group of causes.

There are many different groups of causes of recurrent stones such as malformations, urinary tract stenosis, urinary tract infections, renal tubular acidosis, polycalciuria due to increased calcium excretion from bones, increased calcium absorption from the intestines and kidneys, primary polyoxaluria or dietary polyuricemia, and polyuricemia.
