I've noticed my taste for things changes every 10 years or so.
Things i enjoyed eating 10 years ago i will not eat today.
This happen to me with milk. I used to drink it everyday and now i can't drink it at all.
Maybe try mixing them with some ham, onions, garlic and bell peppers; spice them up a bit.
I cannot eat plain eggs anymore, they have to be spiced up with something.
I used to eat 5-6 plain boiled eggs everyday no problem, not anymore.
