(KAIT/NBC) - Calcium is essential for our bodies and it's recommended that we all get 1,000 milligrams a day.
But that advice may be doing more harm than good in African American men.
Studies have linked too much calcium in the body to aggressive cancers.
Constance Hilliard of the University of North Texas says African Americans are consuming 400 times the calcium as their ancestors.
Men with West African ancestry have a different genetic makeup that prohibits calcium absorption.
And like their ancestors, their bodies are made up to safely consume just 200 milligrams of calcium a day.
"What I think is absolutely crucial at point is that there really has to be research directed at calcium intake but as it relates to different populations," Hilliard said.
It's too soon to say whether her research will result in dietary guideline changes.
