This is how the food chain worked pre-agriculture:

grass grows -> animal eats grass -> human eats animal -> human is healthy

Post-agriculture the food chain looks like so:

human cultivates grain -> human feeds grain to barn animal -> human eats animal -> human gets fat and sick

Most people can accept that human evolution is inextricable from the food chain. The leap we need to make is to accept that human health is enmeshed with our place in the food chain.

This is hard to do because certain reductive thinkers have turned the paleolithic nutrition plan into a “meat” diet, or a “caveman” diet. Paleo is bigger than that. We don’t want to replicate the lifestyle of cavemen. We want to be healthy and we know we can’t be outside of an ordered and natural food chain.
