What is the kidney stone diet?
To avoid a recurrence of kidney stones, or to prevent them developing in the first place, people should drink plenty of water, limit salt and animal protein, limit foods high in oxalates, and be cautious about taking too much calcium in supplements.
Foods that may prevent kidney stones
The following are some suggestions on what to contain in a diet to avoid the formation of stones.
Calcium and oxalate-rich foods
A person should contain foods rich in calcium, particularly if consuming foods that are higher in oxalate such as spinach. The calcium and oxalate bind together in the intestines, reducing the formation of stones.
Fruits and vegetables
Fruits and vegetables are an essential part of any diet. Increasing the number of vegetables in their diet can help a person prevent stone formation. Fruits can be dried, frozen, or fresh. Fruits rich in citric acid have also been shown to have a positive effect in preventing kidneys stones.
Including extra water in the diet can help prevent the formation of both uric acid and cystine stones. Including other liquids in addition to water is acceptable; however, it is significant to check sodium levels in the beverage.
Small amounts of animal-based proteins are fine. However, too much animal protein can raise the risk of developing kidney stones. Plant-based protein sources, however, are encouraged. Examples include beans, peas, and lentils. People should discuss their individual protein needs with a doctor or a dietitian, as wants will vary from person to person.
