Isn't that always going to be the case, regardless of ingredient adjustment? It feels like people who have had very little food will tend towards over-compensating during times of glut - perhaps not so much the generation directly affected, but the care they give to next generations.

As an example vaguely related but less extreme; I was born in 1970 in England to a lower middle-class family. My parents were wartime and post-war babies who had experienced rationing and as a result, I have very strong recollections of being made to "clear your plate" before I could leave the table. (Ironically given this topic, the "there are starving children in Africa who would like that" line was given quite often)

Wasting food was the absolute highest sin I could commit and that's stayed with me to this day.
