The Gemara [Brachos 35a] says that if you eat without a bracha it is like stealing [the food - Maharsha] from Hashem.
If so, Goyim should not be allowed to eat without a bracha just as they may not steal?!
It should also be אסור to give food to a Goy lest he eat w/o a bracha and the giver will transgress לפני עוור?!
