Yes, the advice many of us received (e.g. super low fat) and the financial constraints many of us faced (or that our parents faced) do influence our food choices, for sure.
Eggs: I have had success getting my daughter to enjoy these by trying to make them different than the norm. So, sometimes I make a veggie omelet/frittata, into which I put a bit of ham or bacon or something...just a bit...because that's what she likes more than the veggies. But the veggie taste sort of disappears...
I also make "sweet" omelettes with sliced apple, or even leftover sweet potato and cinnamon and put a bit of maple syrup on that...she loves those. Sort of like a big protein pancake.
And I make Japanese Okonomi (or similar styled) with ginger, green onion, spinach or other veggies and okonomi sauce (which is salty/soy based and also a bit sweet).
And sometimes I give her devilled eggs with paprika and curry...she loves it because it is a change.
Oh - another way to sneak eggs in is to give French toast!
