I’m currently in the US staying with my girlfriend (we’re in a long-distance relationship) and her family. Been here for a month, have 2 more to go. Where I’m from (Romania) “breakfast foods” are not a thing. Breakfast is a full, proper meal just like lunch and dinner. Since being here, I haven’t been able to get accustomed to the concept of “breakfast foods”. Cereal, pancakes, waffles, bacon, eggs, toast, sandwiches, etc. These are like side dishes or snacks to me. I just don’t feel sated. Gave up on that. Now I’m back to eating what I normally do for breakfast: steak, pasta, rice, soup, stew, chicken, fish/seafood, etc.
As an older American from the deep south, it’s just a holdover from cheap high calorie/high carb foods to start the day back when America was mostly agrarian.
Then when the 50s rolled around it got combined with nutrition concepts of a “balanced breakfast” by cereal marketing firms and romanticized to sell even cheaper products to children/parents; sugared cereal.
For me, breakfast is bacon, eggs and biscuits or toast. And maybe grits if I’m feeling like it. I like hash browns but I don’t like making them.
It’s just leftover marketing. Eat what makes you happy.
