Though there are separate blessings for fruit, vegetables, non-bread grain products, and meat, fish, and dairy products, a meal is not considered to be a meal in the formal sense unless bread is eaten. The duty of saying grace after the meal is derived from : "And thou shalt eat and be satisfied and shalt bless the Lord thy God for the goodly land which he has given thee." Verse 8 of the same chapter says: "The land of wheat and barley, of the vine, the fig and the pomegranate, the land of the oil olive and of syrup." Hence only bread made of wheat (which embraces spelt) or of barley (which for this purpose includes rye and oats) is deemed worthy of the blessing commanded in verse 10.
