I love looking at the really old cookbooks and then the revised versions. You can be amazed at how much the "fat" contents of alot dishes are adapted to todays standards.
I have the really old Purity Cookbook...it was a wedding gift from my former MIL and is around 40+ years old. Alot of pages are missing from the cover falling off and the binding letting go, but the difference between that one and the newer version one of my girls got me about 10 years ago is amazing. The recipe names are the same....only the ingredients have changed to protect the health conscious!
