Luckily for us, there are other ways to achieve the same effect as Pam in our cooking by using non-propellant oil misters that produce the same output. Oil misters aren't quite as slick as aerosol pans, because you have to manually pump them each time that you want to grease a pan. But, the benefit to using them is (1) the lack of propellant and (2) the ability to pick your own oil to grease your pans with!
There is one spray mister on Amazon that I personally use called the Norpro Stainless Steel Sprayer Mister. But, any manual spray mister that you find and buy at your local store should work as a sufficient Pam substitute.
I'll be referring to manually greasing pans in future recipes on Yummy Diet Food, so now you'll know what I mean. :)
