Are high-calcium diets related to kidney stones?
No. Recent research even indicates that consuming milk and milk products could help prevent some types of kidney stones. This means that people at risk of developing kidney stones do not need to eliminate milk products from their diets, as these products are a way to maintain bone health. However, calcium in the form of supplements does not seem to provide the same protection as the calcium from food. Moreover, people who take mega-doses of vitamin C supplements could also be at risk of developing certain kinds of kidney stones.
