Three or more servings of dairy each day may help younger women reduce their risk of kidney stones.
Researchers from Brigham and Womens’ Hospital in Boston, Mass., and the Harvard Medical School examined the relationship between dietary factors — like calcium intake from food — and the risk of kidney-stone formation among 96,245 women who participated in the Nurses’ Health Study II. Participants ranged in age from 27 to 44 years old and had no history of kidney stones.
The results show women who ate the most dietary calcium — the equivalent of three or more servings of dairy per day — had the lowest risk of forming kidney stones during the eight-year study period.
In contrast, calcium supplements did not have an impact on the risk of kidney-stone formation.
The research was published in the April 26 Archives of Internal Medicine.
