What is the difference between の中に and の中で?


I have two sentences having の中に (no naka ni) and の中で (no naka de), and I want
to know if they are correctly framed.

If yes, then how does the meaning change?

> 日本{にほん}の食{た}べ物{もの}の中{なか} **に** 寿司{すし}が大好{だいす}きです。  
>  Nihon no tabemono no naka ni sushi ga daisuki desu.  
>  日本{にほん}の食{た}べ物{もの}の中{なか} **で** 寿司{すし}が大好{だいす}きです。  
>  Nihon no tabemono no naka de sushi ga daisuki desu.

Please let me know if there are any grammatical mistakes.
