The author begins with the extremely simple question of "what we should have for dinner?"

Confused ? Yes, we all are. All the time. Because we have choices. Because we are omnivores. Omnivores are unselective eaters - we eat anything and everything. So, what to eat will essentially be the question that'll always rattle us. 

In the first section, he talks about corn - a staple diet of the US. He underlines how it has changed the dietary habits of the Americans. He talks about a calf which is fed corn and then becomes sick but firms look at it as a cost of business. 

In the second part, he talks about food processing units that advertise and thus, increase the demand for organic food. He posits that organic farming industry makes people hallucinate that food comes from lush green vegetations while it actually comes from science operated and technology driven factories.

In the third part, he talks about a farmer who's engaged in mixed farming. How cultivating and animal husbandry go hand in hand remain the main themes here. 

In the final part, he starts preparing a meal from the animals he has hunted and the plants he has gathered. He concludes that fast food and hunter gatherer food are equally unreal and unsustainable. We eat by the grace of nature, not industry.
