CALCIUM INTAKE LOWERS THYROID RISK IN WOMEN

A small dose of calcium can significantly decrease a woman’s risk of developing primary hyperparathyroidism, American researchers say.
In a study of 58,354 women, aged 39-66, over 22 years, researchers from the Harvard Medical School found a daily supplement of at least 500 milligrams of calcium more than halved the risk of developing hyperthyroidism, and low calcium diets were associated with a higher incidence of benign parathyroid adenoma formation.
Calcium intake could influence production of the parathyroid hormone, they report in the BMJ.
When women were divided into five groups according to their level of calcium intake, those who had the highest intake of calcium had around half the risk (0.56) of developing primary hyperparathyroidism, compared to women with the lowest intake, and women who took more than 500mg of calcium a day had a 40% lower risk than those who had no calcium supplements.
In an accompanying editorial, James Norman, chief of surgery at the Norman Parathyroid Centre in Florida, said daily calcium supplements “are likely to provide more benefits than risks given that even mild primary hyperparathyroidism has important clinical associations,” he said.
