We're not greedy for nutriment; we're greedy to avoid dying---we crave continued existence. Nutriment prevents death. It may also be the subject of other cravings (gluttony), but we need to eat to be able to practice. That our bodies are also nutriment for others is emblematic of this place called samsara; beings are programmed to kill other beings to survive, especially the ones you've mentioned. In most cases their bodies are literally configured to exist on a diet of sentient beings.
