Calcium Supplements May Raise Women's Heart Risk
Taylor Wallace, a representative of the supplement industry, faults this study because, he said, it was not specifically meant to address calcium supplements and heart disease.
"We are comparing apples and oranges," said Wallace, who is senior director for Scientific & Regulatory Affairs at the Council for Responsible Nutrition. He noted that in the new study, the data that researchers used to draw their conclusions looked at diet and cancer, not whether calcium supplements were bad for the heart.
"Still, there is not a single human cause-and-effect study that demonstrates a hazard for calcium either from the diet or supplements and cardiovascular disease," he said.
Although the new study tied total calcium intake to increased risk of death from heart disease in women, it didn't establish a cause-and-effect relationship.
Wallace did say it's important to know how much calcium a person is getting from diet and supplements. "It is important to talk with your doctor to make sure you are getting the right amount for you," he said.
For his part, heart association spokesman Fonarow said: "While further studies are needed, calcium supplements should be used only after careful consideration of whether the potential benefits in terms of bone health outweigh the potential cardiovascular risks."
