Does diet play a role kidney stone?

Condition analysis:
Diet plays an important role in the development of kidney stones, especially in patients who are predisposed to the condition. A diet high in sodium, fats, meat, and sugar and low in fiber, vegetable protein, and unrefined carbohydrates increases the risk for renal stone disease. High doses of vitamin C (ie, more than 500 mg per day) can result in high levels of oxalate in the urine (hyperoxaluria) and increase the risk for kidney stones. Oxalate is found in berries, vegetables (eg, green beans, beets, spinach, squash, tomatoes), nuts, chocolate and tea. Stone formers should limit their intake of cranberries, which contain a moderate amount of oxalate.

Instructions:
Magnesium: Magnesium may be an effective natural remedy for kidney stones by preventing crystal formation of minerals, such as calcium. Research indicated that people who had recurrent stones had a 90 percent improvement rate when they took a magnesium supplement. The recommended daily dose to decrease kidney stone formation is 300 mg. If you prefer to get your magnesium from your diet, consider eating foods, such as black beans, broccoli and pumpkin seeds. Other good choices of magnesium-rich foods include oatmeal, nuts and spinach.
