our biological hunger imperative doesn’t imply eating animal products. Roadkill, freshly killed animals, dairy, eggs are not inherently appetizing to humans. If anything it’s the opposite, a dead body is repulsize to most people. A huge percentage of humans are lactose intolerant. Raw eggs are gross. Fruits are about as close as you can get to biological hunger imperative, the other stuff we learn to like and/or cook to make it taste good
