The paleo diet is relatively low in calcium content. So is that a reason to take a calcium supplement? Probably not. Calcium supplements are problematic. They may increase the risk of heart attacks. They may raise the odds of premature cardiac death in men. High calcium consumption increased the risk of death in Swedish women.
MedicalNewsToday has a brief report on dementia in women with cerebrovascular disease and calcium supplements:
“Calcium supplements may increase the risk of developing dementia in senior women with cerebrovascular disease, finds a study published in Neurology, the medical journal of the American Academy of Neurology.
Women who took calcium supplements were twice as likely to develop dementia.Cerebrovascular diseases are conditions caused by problems that affect the blood supply to the brain. The four most common types of cerebrovascular disease are stroke, transient ischemic attack (TIA), subarachnoid hemorrhage, and vascular dementia.”
