Experts believe that there are other various factors, such as obesity, excessive consuming the meals that contain sugar level and salt, age effect, lack of drinking some water.
A study published by Journal of Urology, A team of researcher has measured the calcium level of some meals from dairy products and non-dairy related decreasing the risk of kidney stones.
In Portland, Dr. Eric Taylor from the Maine Medical Center led the research in order analyzing three separate studies, its scope are Nurses Health Study I, Nurses Health Study II and Health Professionals Follow-up Study. The study engage more than 1 million healthy men and women aged less than 60 years old during 20 years. Surveys conducted every 4 years, which the participants were required to fill out the survey forms as a part for knowing the intake frequency of meals to determine its calcium intake. They were separated into five groups adjusted on level of calcium intake.
Twenty years of surveys period have been achieved and the result was obtained that participant groups with high calcium intake about 77 percents showed lower risk of kidney stones than the low calcium groups.
The groups are meet 450 milligrams of calcium intake each day from non-dairy products show better risk to be spared from the kidney stones while other groups are meet 800 milligrams of calcium intake from dairy products only show about 30 percents risk of kidney stones compared those groups who meet 150 milligrams calcium intake.
Other data declared that you should not restrict the calcium intake for preventing kidney stones. But most stones formed from calcium oxalate. Nevertheless, you don’t be afraid to keep taking calcium intake for your body. (Dr. Eric Taylor's quote)
