Women who consume too much calcium, via the food in their diet or calcium supplements, may be at a much higher risk of dying from heart disease, this according to a new study released in Sweden this week.
The study involved 61,443 Swedish women. The women were monitored for 19 years and, during this time period, there were almost 12,000 deaths. Of those 12,000 deaths, nearly 4,000 were the result of cardiovascular disease an nearly 1,900 from ischemic heart disease.
The participants in the study who consumed the lowest amounts of calcium took in about 72 milligrams a day. The participants who took the highest amounts consumed 2,137 milligrams per day. The recommended amount of calcium for women over 19 years of age is 1,000 milligrams a day.
To put things into perspective, 1 cup of milk contains 300 milligrams of calcium. 2 slices of processed cheese contains approximately 265 milligrams of calcium. To see a chart of calcium amounts and popular foods, click here.
The results of the study showed that women taking calcium tablets with a dietary intake over 1,400 milligrams per day 1.5 times more likely to die from cardiovascular disease than those getting 600 to 999 milligrams a day.
“High intakes of calcium in women are associated with higher death rates from all causes and cardiovascular disease but not from stroke,” Dr. Karl Michaelsson, a clinical professor in the department of orthopedic surgical sciences at Uppsala University and co-authors concluded in this week’s issue of the British Medical Journal.
The study also notes that “Women taking calcium tablets with a dietary intake above 1,400 milligrams per day were 1.5 times as likely to die from cardiovascular disease than those getting 600 to 999 milligrams a day.”
