I wonder if it's also the preparation method. Steamed veggies are of course not appealing vs ones flash fried in a little oil/butter plus salt.
My parents always steamed them to hell and put almost no salt on

I don’t buy the saturated fats thing either, except to the extent that they are a source of calories. If you have links to some studies that indicate negative outcomes vs the same caloric intake from other sources I am willing to read them.
