    Why you should stop buying vitamins and get more sleep instead

    Almost half of all Canadians regularly take at least one nutritional supplement such as vitamins, minerals, fibre supplements, antacids and fish oils. Many of these individuals are healthy and hoping to improve general well-being or prevent chronic disease. Scientific evidence, however, suggests that some high-dose nutritional supplements — such as beta carotene, vitamin E and vitamin A — have little role to play in the prevention of chronic disease among healthy individuals, unless there is a diagnosed deficiency of specific micronutrients. Research suggests these supplements might actually do more harm than good. As a medical doctor and public health specialist, I have been [...]

    Toxic, long-lasting contaminants detected in people living in northern Canada

    Researchers have recently found that several long-lasting human-made contaminants have been building up in Arctic lakes, polar bears and ringed seals and other wildlife.

Metabolites are essential molecules that flow through the blood to keep the body functioning. Some of these hard-working metabolites are amino acids that are absorbed and converted into protein needed for muscle strength and endurance. During times of high demand, if nutrient intake is incomplete, nutritional supplements can help fill [...]
