I shall look into this soon, as I am currently quite busy. I just realised that I put in ModItems when I meant ModFoods, so that part would be correct, it is just my mistake...
I'm guessing that's so people can implement their own custom animated models? I really don't know though, since I've never had to use that at all. I just know that you can have more control over a block entity model than over a standard block model, as well as use animations. I'm glad I could help, though!
