Bread is a staple of life. Therefore, Jesus said of Himself,

“I am the bread of life. Your fathers ate the manna in the wilderness, and are dead. This is the bread which comes down from heaven, that one may eat of it and not die. I am the living bread which came down from heaven. If anyone eats of this bread, he will live forever; and the bread that I shall give is My flesh, which I shall give for the life of the world” (John 6:48–51).

He is the staple of life. Therefore, we ingest Him, and live! When He explained that the bread He would give was His flesh, the Jews listening to Him should have noticed right away that He used “bread” symbolically, but they had trouble understanding Him.
