An excellent illustration of how medical science and science in general continuously questions and evaluates accepted practices and ideas, is exemplified by a study on cardiopulmonary resuscitation (CPR) recently published in Circulation: Journal of the American Heart Association. The results demonstrate that people have better chances to survive when more chest compressions are used.

As I have stated quite emphatically on recent editions of Sunday House Call, we consume too much salt and most of it is derived from food manufacturers and restaurants.

Cardiovascular disease is the number one cause of death in Canada with three out of four people having a lifetime risk of dying from it. An report published in the Canadian Medical Association Journal (CMAJ) looked at the effect excess sodium has on Canadians and how straightforward reductions in salt intake could have a positive impact on public health saving lives and reducing health care costs.
