What exactly is propellant? According to the Times it includes “petroleum gas, propane, and butane.” How about a little side of that with your cookies? Do you want a propellent in your food that you serve to your family? You make the choice!
I looked at my can of cooking spray and yes there it was. Propellent was listed as one of the ingredients.
Another thing listed was 2000 calories. It was not from fat but still a lot of calories. So weight watchers be careful and read the label.
