Does it not also say; "Never eat on an empty stomach, without
first having a large portion of food?"
The UB dosn't talk about how to eat but it does talk about hate filled people like you:
"(Jesus then directed his remarks to all present. He said: “But hearken to me, all of you. It is not that which enters into the mouth that spiritually defiles the man, but rather that which proceeds out of the mouth and from the heart.” But even the apostles failed fully to grasp the meaning of his words, for Simon Peter also asked him: “Lest some of your hearers be unnecessarily offended, would you explain to us the meaning of these words?” And then said Jesus to Peter: “Are you also hard of understanding? Know you not that every plant which my heavenly Father has not planted shall be rooted up? Turn now your attention to those who would know the truth. You cannot compel men to love the truth. Many of these teachers are blind guides. And you know that, if the blind lead the blind, both shall fall into the pit. But hearken while I tell you the truth concerning those things which morally defile and spiritually contaminate men. I declare it is not that which enters the body by the mouth or gains access to the mind through the eyes and ears, that defiles the man. Man is only defiled by that evil which may originate within the heart, and which finds expression in the words and deeds of such unholy persons. Do you not know it is from the heart that there come forth evil thoughts, wicked projects of murder, theft, and adulteries, together with jealousy, pride, anger, revenge, railings, and false witness? And it is just such things that defile men, and not that they eat bread with ceremonially unclean hands.”*
