Researchers at the University of California studied that extra Zinc content lead to formation of kidney stones & kidney stones arise out of crystallization of minerals that deposit as hard masses inside the kidney. According to the National Kidney Foundation in the U.S., lifestyle factors such as abundance or scarcity of physical exercise, dehydration, consumption of excess salt or sugar and weight loss surgery may contribute to the formation of kidney stones majorly.
Study findings show that interaction of zinc with calcium, oxalate and other minerals can form kidney stones. Zinc facilitates the calcification and mineralization process in the Kidneys.
Researchers concluded that increased dietary intake of zinc, the level of oxalate in the urine increased as well. Oxalate levels in urine are a known risk factor for kidney stones.
Researchers are still in findings of knowing the mechanism of Zinc relation in formation of kidney stones so as to reach the target to prevent kidney stones formation.
