With regard to the nutrients you identified, trans fat and sodium, excess sodium intake is responsible for about four times as many deaths as trans fat by some estimates. However, we're still talking about thousands of premature deaths per year. The World Health Organization, in May of this year, issued a scientific update on trans fat, indicating that the scientific case is even stronger for getting it out of the food supply. But we still have this voluntary program, and we're waiting to find out if the Minister of Health is going to make good on Health Canada's call for regulations in the absence of strong action from industry.
There are other factors to consider too. Canadians get inadequate intakes of fruits and vegetables and whole grains and legumes, and those are all important risk factors. They're just not as well studied in terms of the actual population level implications in terms of premature deaths, but they are important too.
