Nonsense, Luthy. Valar are gods, but they're not eatible 'cause they have no substance.
Ulmo, for instance, the God of Waters, is the spirit that animates rivers and seas and so on, and he can show himself to you as rush of rain and such, or you can hear his whispering listening very carefully a river flowing, but you cannot roast him, or put any sauce on him, or whatever.
