The Food of The Gods varies depending on the location and the religion. In Christianity, it is Ambrosia or Manna. In India and Hindu writings, it is usually butter. In other religions, it might be Sacramental Cakes. All of these are said to represent truth, love, divine knowledge, and spiritual nourishment for the soul. In other words, it represents God's Grace or God's Light which awakens the soul from it com-like sleep and give it nourishment so you can grow spiritually and eventually become fully enlightened.

“O Heavenly Springtime! I have come into Thee; I have eaten my sacramental cakes; I have power over the sacrificial portions of my beasts and birds; the feathered foul of the light are given unto me, for I have followed the gods when the divine forms come.” The Book of the Dead.

    What this quote is saying symbolically is that the Ambrosia, or Food of the Gods, gives one power over the lower self and the ego by nourishing the soul and spirit and giving it strength and knowledge. That lower forms of worship such as sacrificing animals is no longer necessary or desirable because one has risen above such primitive forms of faith and the self becomes truly actualized.
