Did you see the first season of Top Chef? It was hosted by someone widely criticized for not bringing insight to food. That person was quickly replaced by renowned chef Padma Lakshmi.

The host change in Top Chef and the emphasis on descriptive skills on Food Network Star demonstrate how vital it is for these shows to be able to not just make food, but describe it.
