btw, the film and book are based in an earlier generation, the current very old folks, pre 1980s industrial foods boom and SAD marketing (which happened later than in the US/UK I believe?).
IE, dessert usually only once a week on Sundays for regular folks, low meal frequency, pasta/bread as small saucer sides (miniscule servings compared to the “normal” American version at Mararoni Grill and Spaghetti Factory etc).
I found the interview with an Italian chef talking about his childhood customs within his intergenerational family compared to today’s customs really relevant - and tasty. The afternoon nap and eating only twice a day is another thing.
