I never really liked Angel Delight either - or Instant Whip. Anyone remember that? I think those things really were the beginning of processed food (including boil in the bag, Vesta and pot noodles).
And yes, I remember a bag of crisps as a Friday evening treat, when I was about 4 (this would be in maybe 1965/6). That would be a regular size bag of Golden Wonder shared amongst three sisters...
I think as well as our portion sizes, our expectations were a lot lower in those days!
I also think there is much more pressure from society to "indulge" these days. In the 60s, most people ate in their own homes, not out so much. Things like taking cakes into work was almost unknown. Nowadays it's normal to bring cakes into work/school etc, and if you don't join in you are seen as being boring or different or weird (unless you can claim a medical reason not to eat the stuff).
I was interested to read StuntNun's post on the previous thread about SOS (Socially Obligated Sugar). That really made me think. Why should we be socially obligated to eat sugar we neither want nor need? There's something wrong with society isn't there?
Sorry, just my musings after coming home from a concert my ds was playing in and realising that no, I'm not even thinking I want a snack, after last eating at around 6 pm.
