Yes, I can eat the food.
The problem is, well, I make a stew, I store it, I make a cake, I store it, and when I click eat leftovers, I can't choose which leftovers from both, nor I have an option to throw one and eat the other.
It's more a feature request than a bug.
The game already has a system to let you choose which leftovers your Sim eats. Click Open on the refrigerator, which opens the Inventory panel with a section showing what's in the fridge. Click on the food you want to eat and Grab a Serving. You can use the same method to select foods to throw away.
