Stephen Seely, MD, cardiologist and researcher, wrote in his 1991 article "Is Calcium Excess in Western Diet a Major Cause of Arterial Disease?" published in the International Journal of Cardiology:

“The general observation can be made that, in countries where the daily calcium intake is 200-400 mg, arterial diseases are non-existent. Blood pressure does not increase with age. In countries where the daily intake is 800 mg, arterial disease is the leading cause of mortality. A more specific indicator is the strong positive correlation between consumption of milk and mortality from coronary arterial disease.”
