Unveiling the ban last year, but giving industries a year to change, Canada's ban on artificial trans fats is now in effect.

The main target will be products that include partially hydrogenated oils, which is the main source of industrially made trans fats throughout Canada.

It's expected to lower the number of heart attacks throughout the country, as businesses rid their food of the additive which adds taste and texture to food, instead of using butter. The problem, however, comes from the levels of harmful cholesterol that comes with the fats.

Products that were manufactured before this week are still allowed to be sold while containing trans fats, but only for the next 2 years.
