"food" references in the book of John

I have been reading through the gospel of John and there are a couple of verses related to food.

In 4:34, "My food," said Jesus, "is to do the will of Him who sent me and to finish His work."

6:27, "Do not work for food that spoils, but for food that endures to eternal life, which the Son of Man will give you."

6:35 "I am the bread of life. He who comes to me will never go hungry and he who believes in me will never be thirsty."

The message to feast on Jesus is quite evident here. I am often convicted that when I am bingeing, I have a "wrong focus" and that if I were truly seeking "the bread of life," my desire for food that spoils would disappear.
