I'm never usually for intrusive regulation, but I'm going to side with Croc on this one.
My country is mulling a similar ban, and already many snack foods (such as Lays) up here have had their trans fats eliminated, which helps to prove that changing the recipe isn't that hard. One of our cookie companies, spent almost half a million dollars changing their recipe and eliminated Trans Fats. Their sales have increased because many of Nabisco's offerings still contain these fats.
Eateries should follow suit because Trans Fats are becoming a major factor in heart disease and obesity in general. These fats have a tendency to go straight around your abdominal muscles, thus poorly affecting your health.
However, people will instantly think McDonalds is the culprit for all this. In fact, McDonalds, at least in Canada, has the lowest average Trans Fat amounts in their food, because the company is actively trying to reduce the amounts of partially hydrogenated fats.
You'd be surprised to realize that Starbucks had the highest average of Trans Fats in it's foods. CTV News Link and that some of its beverages have more fat than a Big Mac...
For the sake of our well being, these fats should be banned.
