TORONTO - New Canadian research provides some bad news for lovers of fast-food breakfast sandwiches.
A study done at the University of Calgary shows that even in young healthy volunteers, these high fat meals have an almost immediate, though temporary, effect on the functioning of blood vessels.
Scientists at the Libin Cardiovascular Institute tested what they call the "happiness" of blood vessels after volunteers ate two breakfast sandwiches, comparing the results to controls who didn't have the meal.
They measured the velocity of blood flow to the subjects' arms, and found it was significantly reduced after the breakfast sandwich meal.
Senior author Dr. Todd Anderson says the study doesn't mean people should never eat a breakfast sandwich.
But he suggests it shows that every choice has an impact, and that too much of a diet like that could lead to a build up of fat in the walls of one's arteries.
The results of the study were presented Tuesday to the Canadian Cardiovascular Congress.
